I have generated a C# SharePoint Sequential Workflow project using the very handy STSDEV tool (it got me around the requirement to have access to a 32-bit SharePoint installation which is required for other tools such as VSeWSS 1.3).
I've added a simple 'modify the title' action to test my basic setup:
public sealed partial class CopyWorkflow : SharePointSequentialWorkflowActivity
{
public CopyWorkflow()
{
InitializeComponent();
workflowProperties = new SPWorkflowActivationProperties();
}
public SPWorkflowActivationProperties workflowProperties;
private void onWorkflowActivated1_Invoked_1(object sender, ExternalDataEventArgs e)
{
workflowProperties.Item["Title"] = workflowProperties.Item["Title"].ToString() + ": Processed by Workflow";
workflowProperties.Item.Update();
}
}
Whoever, after installing my workflow via WSP into an installation of WSS 3.0, activating the feature, and configuring the workflow to start whenever a new item is created for a particular list, I get my breakpoint in onWorkflowActivated1_Invoked_1 hit, but the workflowProperties.Item is always NULL instead of an SPListItem representing the item that was just added.
What do I need to do to get the Item to be filled when this callback is called?
Update: I've noticed that the thread executing the workflow is running anonymously rather than as the logged in user or the system user, and therefore won't have access to the list data. Furthermore, the SharePoint log file show the following exception:
Unexpected System.ArgumentNullException: Value cannot be null. Parameter name: uriString at System.Uri..ctor(String uriString) at Microsoft.SharePoint.SPSite..ctor(String requestUrl) at Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties.<get_Site>b__0() at Microsoft.SharePoint.SPSecurity.CodeToRunElevatedWrapper(Object state) at Microsoft.SharePoint.SPSecurity.<>c__DisplayClass4.<RunWithElevatedPrivileges>b__2() at Microsoft.SharePoint.Utilities.SecurityContext.RunAsProcess(CodeToRunElevated secureCode) at Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges(WaitCallback secureCode, Object param) at Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges(CodeToRunElevated secureCode) at Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties....

Have you bound WorkflowActivationProperties with Workflow designer?
WorkflowActivationProperties http://img718.imageshack.us/img718/9703/ss20100305091353.png
This issue occurs if the the InitialStateName of the designer in the workflow properties is not equal to "Initial state" or is pointed to other stage abruptly.
Once a state wherein we have the workflowProperties ,etc like the above image. Things start working as required.

I would like to override the standard method of the RowSelected event on the Service Orders screen. Specifically, the DocDesc field gets populated when you select a row item for the Labor tab. It will set the TranDesc to the DocDesc and I would like to keep this from happening. I am using Acumatica 6.1 which means that the Service Management Module is not standard in Acumatica during this time. I would like the method that populates this field to not run when the labor line is populated, so the DocDesc field would remain null or blank, this way the user can input their own description.
You should be able to customize the ServiceOrderEntry graph like any other graph :
protected virtual void FSServiceOrder_RowSelected(PXCache sender, PXRowSelectedEventArgs e, PXRowSelected bs)
{
...
}
See https://help.acumatica.com/(W(3))/Main?ScreenId=ShowWiki&pageid=4a05d4c2-cd8b-4131-bf3b-d05861de3ae6
You could override the method if it is virtual, like this :
public delegate void PersistDelegate();
[PXOverride]
public void Persist(PersistDelegate baseMethod)
{
...
baseMethod();
...
}
See https://help.acumatica.com/(W(3))/Main?ScreenId=ShowWiki&pageid=635c830e-4617-4d5c-9fa5-035952311aa9
You could also modify the base customization, but since you are not the owner it could get difficult to maintain and track the changes.
We're using the Run Project Billing screen to create records in AR / Invoice and Memo.
In the Invoice & Memo screen, we need the process to populate the header Customer Ord. number, along with a user field that has been added to the grid section on the 'Document Details' tab. At the moment, the process is not doing this.
I'd like to intercept the processing action on the screen using a technique I'm familiar with, namely using an 'AddHandler':
[PXOverride]
protected virtual IEnumerable Items (PXAdapter adapter)
{
PXGraph.InstanceCreated.AddHandler<BillingProcess>((graph) =>
{
graph.RowInserting.AddHandler<BillingProcess.ProjectsList>((sender, e) =>
{
//Custom logic goes here
});
});
return Base.action.Press(adapter);
}
I see no Base.Actions that remotely resembles 'Bill' or 'Bill All'.
This is obviously not exactly the code I need, but I would think this is the general place to start.
After reviewing the source business logic, I don't see any 'Bill' or 'Bill All' Actions - or any 'Actions' at all (baffling). I see an IEnumerable method called 'items', so that's what I started with above.
Is this the correct way to go about this?
Update: 2/14/2017
Using the answer provided re: the overridden method InsertTransaction(...) I've tried to set our ARTran user field (which is required) using the following logic:
PMProject pmproj = PXSelect<PMProject, Where<PMProject.contractID, Equal<Required<PMProject.contractID>>>>.Select(Base, tran.ProjectID);
if (pmproj == null) return;
PMProjectExt pmprojext = PXCache<PMProject>.GetExtension<PMProjectExt>(pmproj);
if (pmprojext == null) return;
ARTranExt tranext = PXCache<ARTran>.GetExtension<ARTranExt>(tran);
if (tranext == null) return;
tranext.UsrContractID = pmprojext.UsrContractID;
Even though this sets the user field to the correct value, it still gives me an error that the required field is empty when the process finishes. My limited knowledge prevents me from understanding why.
On the Run Project Billing screen, captions of Process and Process All buttons were changed to Bill and Bill All respectively in BLC constructor.
Process delegate is set for Items data view within the BillingFilter_RowSelected handler:
public class BillingProcess : PXGraph<BillingProcess>
{
...
public BillingProcess()
{
Items.SetProcessCaption(PM.Messages.ProcBill);
Items.SetProcessAllCaption(PM.Messages.ProcBillAll);
}
...
protected virtual void BillingFilter_RowSelected(PXCache cache, PXRowSelectedEventArgs e)
{
BillingFilter filter = Filter.Current;
Items.SetProcessDelegate<PMBillEngine>(
delegate (PMBillEngine engine, ProjectsList item)
{
if (!engine.Bill(item.ProjectID, filter.InvoiceDate, filter.InvFinPeriodID))
{
throw new PXSetPropertyException(Warnings.NothingToBill, PXErrorLevel.RowWarning);
}
});
}
...
}
As code snippet above confirms, all records in the AR Invoice and Memos screen are created by instance of the PMBillEngine class. Below is code snippet showing how to override InsertNewInvoiceDocument and InsertTransaction methods within the PMBillEngine BLC extension:
public class PMBillEngineExt : PXGraphExtension<PMBillEngine>
{
public delegate ARInvoice InsertNewInvoiceDocumentDel(string finPeriod, string docType, Customer customer,
PMProject project, DateTime billingDate, string docDesc);
[PXOverride]
public ARInvoice InsertNewInvoiceDocument(string finPeriod, string docType, Customer customer, PMProject project,
DateTime billingDate, string docDesc, InsertNewInvoiceDocumentDel del)
{
var result = del(finPeriod, docType, customer, project, billingDate, docDesc);
// custom logic goes here
return result;
}
[PXOverride]
public void InsertTransaction(ARTran tran, string subCD, string note, Guid[] files)
{
// the system will automatically invoke base method prior to the customized one
// custom logic goes here
}
}
Run Project Billing process invokes InsertNewInvoiceDocument method to create new record on the AR Invoice and Memos screen and InsertTransaction method to add new invoice transaction.
One important thing to mention: overridden InsertNewInvoiceDocument and InsertTransaction methods will be invoked when a user launches Run Project Billing operation either from the processing Run Project Billing screen or from the data entry Projects screen.

I’d like to use the liferay notification feature following the tutorial http://www.codeyouneed.com/liferay-custom-notifications/. And as many people before, I succeeded in increasing the number of notifications, but the notification message is not displayed.
I tried to check by adding log-output whether the methods (getBody, getLink, …) of the UserNotificationHandler are called, and they are not called at all, not even the constructor of the UserNotificationHandler is called.
So I conclude that my notification is written to the database, but my UserNotificationHandler class is not found.
In my project, I have put the
user-notification-definitions into
project/src/main/resources.
They look like:
<?xml version="1.0"?>
<!DOCTYPE user-notification-definitions PUBLIC "-//Liferay//DTD User Notification Definitions 6.2.0//EN" "http://www.liferay.com/dtd/liferay-user-notification-definitions_6_2_0.dtd">
<user-notification-definitions>
<definition>
<notification-type>${com.myproject.portal.notifications.UserNotificationHandler.PORTLET_ID}</notification-type>
<description>receive-a-notification-when-triggered</description>
<delivery-type>
<name>email</name>
<type>${com.liferay.portal.model.UserNotificationDeliveryConstants.TYPE_EMAIL}</type>
<default>true</default>
<modifiable>true</modifiable>
</delivery-type>
<delivery-type>
<name>website</name>
<type>${com.liferay.portal.model.UserNotificationDeliveryConstants.TYPE_WEBSITE}</type>
<default>true</default>
<modifiable>true</modifiable>
</delivery-type>
</definition>
</user-notification-definitions>
The liferay-portlet.xml is in
project/src/main/webapp/WEB-INF.
And the UserNotificationHandler in
project/src/main/java/com/myproject/portal/notifications
in the package com.myproject.portal.notifications.
I wrote something like that into the liferay-portlet.xml:
<portlet-name>example</portlet-name>
<icon>/icon.png</icon>
<user-notification-definitions>
user-notification-definitions.xml
</user-notification-definitions>
<user-notification-handler-class>
com.myproject.portal.notifications.UserNotificationHandler
</user-notification-handler-class>
</portlet>
This is my UserNotificationHandlerClass (so far, I am just trying to get it work before adding the actual content):
package com.myproject.portal.notifications;
import ...//all necessary imports
public class UserNotificationHandler extends
BaseUserNotificationHandler {
public static final String PORTLET_ID = "example_WAR_myprojectportlet";
private static final Logger log = Logger.getLogger(UserNotificationHandler.class);
public UserNotificationHandler() {
log.info("UserNotificationHandler - Constructor");
setPortletId(UserNotificationHandler.PORTLET_ID);
}
#Override
protected String getBody(UserNotificationEvent userNotificationEvent,
ServiceContext serviceContext) throws Exception {
log.info("in getBody");
return "";
}
#Override
protected String getLink(UserNotificationEvent userNotificationEvent,
ServiceContext serviceContext) throws Exception {
log.info("in getLink");
return "";
}
protected String getBodyTemplate() throws Exception {
log.info("in getBodyTemplate");
return "";
}
}
I trigger the notification in my portlet like this:
ServiceContext serviceContext = ServiceContextFactory.getInstance(request);
JSONObject payloadJSON = JSONFactoryUtil.createJSONObject();
payloadJSON.put("userId", userId);
payloadJSON.put("yourCustomEntityId", 12345);
payloadJSON.put("additionalData", "success");
UserNotificationEventLocalServiceUtil.addUserNotificationEvent(userId,
UserNotificationHandler.PORTLET_ID,
(new Date()).getTime(),
userId,
payloadJSON.toString(),
false,
serviceContext);
What is the problem here?
Do you literally have public static final String PORTLET_ID = "myportlet"; in your code? If so, note the extra information in the tutorial that you link:
NB Important Information: The com.example.notifications.ExampleUserNotificationHandler.PORTLET_ID string that you use as your notification type has to match an actual portlet ID. It doesn’t actually need to be YOUR portlet ID but that would be the right thing to have there. The reason being that Notifications display portlet uses it to display a small portlet icon next to your notification to help the user identify the source of the notification. Providing a bad Portlet ID or something like null leads to a hard-to-trace NullPointerException in the JSP. Took me an hour to track it down.
Most likely the portlet ID looks rather like "example_WAR_myportlet", this indicates that it's deployed in a plugin named example.war and the portlet id (in portlet.xml) is myportlet. Try if it works then - Liferay might need to find the portlet in order to find, instanciate and use its NotificationHandler. (Note: This is currently a guess - I didn't try the full code posted)
In your liferay-portlet.xml you wrote
<user-notification-handler-class>
UserNotificationHandler
</user-notification-handler-class>
It should be:
<user-notification-handler-class>
com.myproject.portal.notifications.UserNotificationHandler
</user-notification-handler-class>
You should also check if this part is good
<user-notification-definitions>
user-notification-definitions.xml
</user-notification-definitions>
"user-notification-definitions.xml" file should be on WEB-INF/classes in the final WAR
I want to disable Orchard Content Part buttons (Save and Publish Now) in the EDITOR template (when Content Item is created) based on some conditions. Can I do that ? How do I access the buttons in the EDITOR view.
Here are come examples,
To build a content fully from a Controller example, taken from the Blog Module
public ActionResult Create() {
if (!Services.Authorizer.Authorize(Permissions.ManageBlogs, T("Not allowed to create blogs")))
return new HttpUnauthorizedResult();
BlogPart blog = Services.ContentManager.New<BlogPart>("Blog");
if (blog == null)
return HttpNotFound();
dynamic model = Services.ContentManager.BuildEditor(blog);
// Casting to avoid invalid (under medium trust) reflection over the protected View method and force a static invocation.
return View((object)model);
}
[HttpPost, ActionName("Create")]
public ActionResult CreatePOST() {
if (!Services.Authorizer.Authorize(Permissions.ManageBlogs, T("Couldn't create blog")))
return new HttpUnauthorizedResult();
var blog = Services.ContentManager.New<BlogPart>("Blog");
_contentManager.Create(blog, VersionOptions.Draft);
dynamic model = _contentManager.UpdateEditor(blog, this);
if (!ModelState.IsValid) {
_transactionManager.Cancel();
// Casting to avoid invalid (under medium trust) reflection over the protected View method and force a static invocation.
return View((object)model);
}
_contentManager.Publish(blog.ContentItem);
return Redirect(Url.BlogForAdmin(blog));
}
BuidEditor does the work for you.
And you should use a alternative version of this template, but remove the edit link and publish link.
Note, you need a route for you custom create action, and a menu link on the dashboard may come in handy.
I have noticed that the custom properties of a webpart I developed return to their default values when I reboot my machine.
Is that a normal behavior? are the properties saved as far as the server is up, or there is some parameters I am missing.
Thank you.
EDIT: code:
namespace TestWebpart
{
[ToolboxItemAttribute(false)]
[XmlRoot(Namespace = "TestWebpart")]
public class GraphWebpart : Microsoft.SharePoint.WebPartPages.WebPart
{
// Visual Studio might automatically update this path when you change the Visual Web Part project item.
private const string _ascxPath = #"~/_CONTROLTEMPLATES/Test_Graph/TestWebpart/GraphWebpartUserControl.ascx";
protected override void CreateChildControls()
{
ReloadElements();
}
protected void ReloadElements()
{
Controls.Clear();
GraphWebpartUserControl control = (GraphWebpartUserControl)Page.LoadControl(_ascxPath);
control.xmlDataUrl = XMLFileUrl;
Controls.Add(control);
}
private static string _xmlFileUrl;
[WebBrowsable(true),
Personalizable(PersonalizationScope.Shared),
DefaultValue(""),

DisplayName("xml"),
WebDisplayName("xml")]
public string XMLFileUrl
{
get { return _xmlFileUrl; }
set {
_xmlFileUrl = value;
ReloadElements();
}
}
}
}
EDIT2:
Deleting static from the fields throws the flowing exception:
Web Part Error: An error occurred while setting the value of this property: TestWebpart:XMLFileUrl - Exception has been thrown by the target of an invocation.

First of all you should not have
private static string _xmlFileUrl;
it should be
private string _xmlFileUrl;
This static variable will be lost on IISRESET - won't work in a farm and has the potential to cause all sort of 'thread safe' issues if used multi-threaded environment (like a web server) so only use them if they are really needed.
When SharePoint loads a web part (or after you click Save/Apply in the toolpart) it uses reflection to find your properties (the [Browsable... attribute) and then serialization to load/save the value of the property to the database. One of these two is failing.
I would suspect that is some problem with the attribute - try this one and work backwards until it stops working ;)
