Setting command Listener - java-me

I am trying to set a command listener on a particular list in J2ME. While other commands in other displayables in the application works fine, the commands on this particular list don't work. I dont seem to get where I am making a mistake. Below is the code for the List.
List menuList() {
if (mList == null) {
mList = new List("Services", List.IMPLICIT);
//............ the list items are appended
} else {
//............this will display the existing list
}
mList.addCommand(BACK_COMMAND);
mList.addCommand(EXIT_COMMAND);
mList.setCommandListener(this);
return mList;
}
Thanks for the assistance.

How do I transfer rich text attachments from one document to another

I have 2 documents which are supposed work in such a way to be able to transfer files between them. However, it doesn't work. The exception I get is Exception occurred calling method NotesDocument.save() Notes error: One or more of the source document's attachment are missing. Run Fixup to delete the document in the source database. This happens after I try to call save() function on the document to which I've just transfered files from the first.
The functions are below:
function transferFiles(docToGetFrom, docToTransferTo, fileFieldFromFirstName, fileFieldFromSecondName)
{
var rit1:NotesRichTextItem = getFirstNotesRichTextItem(docToGetFrom, fileFieldFromFirstName);
docToTransferTo.copyItem(rit1, fileFieldFromSecondName);
deleteAllFilesFromDocument(docToGetFrom, fileFieldFromFirstName);
docToTransferTo.save();
}
function getFirstNotesRichTextItem(documentToGetFrom, fileFieldName)
{
if (documentToGetFrom == null)
{
return(null);
}
if (!documentToGetFrom.hasItem(fileFieldName))
{
return(null);
}
var rit1:NotesRichTextItem = documentToGetFrom.getFirstItem(fileFieldName);
return rit1;
}
function deleteAllFilesFromDocument(documentToDeleteFrom, fileFieldName)
{
var arr = getAllEmbeddedObjects(documentToDeleteFrom, fileFieldName);
for(var i = 0; i < arr.length; i++)
{
arr[i].remove();
}
documentToDeleteFrom.save();
}
function getAllEmbeddedObjects(documentToGetFrom, fileFieldName)
{
var rit1:NotesRichTextItem = getFirstNotesRichTextItem(documentToGetFrom, fileFieldName);
if (rit1 == null)
{
return(null);
}
try
{
var arr=rit1.getEmbeddedObjects();
return arr;
}
catch(e)
{
return(null);
}
}
According to plain logic, I need to do the following in order to make it work:
Get attachments from the document A
Copy them to the document B
Remove attachments from the document A
Call save() on A
Call save() on B
I did exactly the same, but nevertheless get this nasty exception. Also, I've tried to solve the problem by setting OLEDisableFX to 1, but with no luck. I assume that something must be wrong with the method copyItem() (I guess it can only work properly with simple datatypes). What's the problem? Thanks in advance.
You'll probably need to detach the attachment from the source document and attach it to the target document. See the NotesEmbeddedObject class for examples.
Use the CopyItemToDocument method of the NotesItem class. The following is some code I used in a LotusScript agent but the CopyItemToDocument method is also available in Java and SSJS.
If doc.Hasitem("RTF1") Then
Set item = Nothing
Set item = doc.getFirstItem("RTF1")
Call item.Copyitemtodocument(targetdoc, "targetRTF")
Call item.Remove()
End If

in a civicrm webform, create multiple 'groups' fields

In CiviCRM webform, you can 'enable tag and groups'. Configuring those allows you to create option elements in the webform.
This creates one 'widget', one dropdown or set of checkboxes. I have two field instances where I want the user to select a group - say for example
which mailing lists do you want to receive (a,b,c)
what food are you interested in (d,e,f)
a,b,c,d,e and f are all groups. I can not change that.
How could I do that ?
A technical suggestion below, but first, I'd suggest that your real solution is to not use groups for the second question. Groups are set up nicely to handle mailing lists, but if it's to track interests, you'd be better off setting those up as custom fields. It'll solve this immediate issue, and it'll make it easier to deal with tandem searches and so forth (on list b and likes food d).
Now if you must have them as groups, you can create a fake field and move checkboxes into it using jQuery. Create the fake field with one option that you don't care about, but label it "What food are you interested in", or equivalent. Then, edit the Groups field that CiviCRM generated: label it more specifically as "which mailing lists...", and choose Static Options so it doesn't start offering up just any group for someone to choose.
Now, add the following javascript:
// first remove the dummy checkboxes in your fake field
$('#yourdummyfield .form-item').each( function() { $(this).remove(); });
// now move things into the dummy field
$('#yourdummyfield').append( $('#groupsfield .form-item-d');
$('#yourdummyfield').append( $('#groupsfield .form-item-e');
$('#yourdummyfield').append( $('#groupsfield .form-item-f');
From the form processing perspective, they'll all be evaluated as the "groups" field. However, they'll look separate. For better or worse, this will have to be adjusted as you add new groups fields.
After using Andrew Hunts suggestion for a while, I finally solved this on the server side, in a custom module, using webform logic as described here
http://www.webomelette.com/drupal-webform-submission-presave-hook
Basicly, on presave, I look for 2 custom fields containing group ids (mailing and food in the example). Then I add these to the CiviCRM groups field.
I'll add the code below, which has some more logic:
to make it flexible, I use one hidden field to contain the fieldkey
of the civicrm groups selector to add the other fields in. that
field is called 'the_groups_element' (but its not the groups element, it contains the key of the groups element)
there is only one foods group allowed, so before it adds you to a food group, it removes all other food groups from the groups selector.
You could probably make it even more generic, but since I had different logic for the different groups, this was suitable for me.
function getFoodGroups() {
// return foodgroups
}
function getMailGroups() {
// return mailgroups
}
function MYMODULE_webform_submission_presave($node, &$submission) {
$groupselm = '';
$groups_cid = false;
$foods_cid = false;
$mailings_cid = false;
// http://www.webomelette.com/drupal-webform-submission-presave-hook
foreach($node->webform['components'] as $cid=>$comp) {
if ($comp['form_key']=='the_groups_element') {
$groupselm = $comp['value'];
break;
}
}
if ($groupselm) {
foreach($node->webform['components'] as $cid=>$comp) {
if ($comp['form_key']==$groupselm) $groups_cid = $comp['cid'];
if ($comp['form_key']=='the_foods') $foods_cid = $comp['cid'];
if ($comp['form_key']=='the_mailings') $mailings_cid = $comp['cid'];
}
$group_gids = $submission->data[$groups_cid];
if (!$group_gids) $group_gids=array();
if ($foods_cid!==false && $submission->data[$foods_cid]) {
// remove all current foods
foreach ($group_gids as $gidx=>$group_gid) {
foreach (getFoodGroups() as $foodgroup) {
if ($group_gid==$foodgroup['gid']) {
if ($debug) drupal_set_message('removing foodgroup '.$foodgroup['gid']);
unset($group_gids[$gidx]);
}
}
}
// validate and add submitted regions
$foodsgids = $submission->data[$foods_cid];
if (!is_array($foodsgids)) $foodsgids = array($foodsgids);
foreach ($foodsgids as $foodsgid) {
foreach (getFoodGroups() as $foodgroup) {
if ($foodsgid==$foodgroup['gid']) {
$group_gids[]=$foodsgid;
break; // only one food allowed
}
}
}
}
if ($mailings_cid!==false && $submission->data[$mailings_cid]) {
// just add submitted mailings, dont remove any
$mailinggids = $submission->data[$mailings_cid];
if (!is_array($mailinggids)) $mailinggids = array($mailinggids);
foreach ($mailinggids as $mailinggid) {
foreach (getMailGroups() as $mailing) {
if ($mailinggid==$mailing['gid']) {
if ($debug) drupal_set_message('adding mailing '.$mailing['gid']);
$group_gids[]=$mailinggid;
}
}
}
}
$submission->data[$groups_cid] = array_unique($group_gids);
}

Remove parent div if duplicate words

I'm using a service called Embedly to style my RSS feeds from Google Feedburner. I have an example code over her: JsFiddle
If you look closely you will see the source (CNN) at the end of every title. This is called .provider I would like to get rid of the whole div (.embed) IF the the word CNN is located elsewere (meaning duplicate) in the div, either .description or a
I tried many things, this is one of them really straight forward code:
$('.embed').each(function() {
if($('.embed a:first **could also be .description**', this).text() == $('.provider', this).text())
$(this).remove();
});
I cant figure out why its not working. I also used it with on and live click with no luck.
I just realized the 'embeds' are not there on document tready. I added a button with click event which you can click after the embedly has loaded in: http://jsfiddle.net/2VBSX/37/
You can use success event to filter provider class from the data like this :
EDITED
$('div.newscontainer').embedly({
key: ':3eccf441bf0f43acbb076da9817af27d',
success: function(oembed, dict) {
output = $(oembed['code']);
description = $(oembed['code']).find(".description").text();
var regex =new RegExp(output.find('.provider').text(),"i");
if(regex.exec(description) == null ) {
$(dict["node"]).parent().html(output);
}
output.find("a:eq(0)").text(); // First
output.find("a:eq(1)").text(); // Provider
}
});
Checkout this jsfiddle demo
Is it that what you want?
var regex = /CNN/;
$('.embed').each(function(index, element) {
if (regex.exec($('.embed a:first').text()) != null
&& regex.exec($('.provider').text()) != null) {
element.remove();
}
});

How do I track whether a context menu item is already created by my Chrome Extension?

There are only four methods for chrome.contextMenus:
create
update
remove
removeAll
I am wondering how do I check whether one menu is already created?
I tried this:
try {
chrome.contextMenus.update("byname", {});
} catch (e) {
// doesn't exist
}
But it seems the error cannot be caught (but shown in the console).
Thanks for any kind of tips!
Each chrome.contextMenus.create call returns an unique identifier. Store these identifiers in an array or hash to keep track of them.
This is a direct solution to anyone having the op's problem, based on the suggestion by Rob W. The idea is to maintain your own list of existing context menu id's.
By using these wrapper functions to maintain context menu entries, also the removal and updates are being kept track of (addressing Fuzzyma's comment).
Usage works like Chrome's own methods, eg. createContextMenu({id: "something"}, onclick). It works for me.
let contextMenus = {}
// method to create context menu and keep track of its existence
function createContextMenu() {
if (arguments[0] && arguments[0].id) {
// TODO: not sure if this will work properly, is creation synchronous or asynchrounous?
// take in to account calll back and the runtime error?
chrome.contextMenus[arguments[0].id] = chrome.contextMenus.create.apply(null, arguments);
}
}
function updateContextMenu() {
if (arguments[0] && contextMenus[arguments[0]]) {
chrome.contextMenus.update.apply(mull, arguments);
}
}
function removeContextMenu() {
if (arguments[0] && contextMenus[arguments[0]]) {
chrome.contextMenus.remove.apply(null, arguments);
contextMenus[arguments[0]] = undefined;
}
}
function contextMenuExists(id) {
return !!contextMenus[id];
}

SharePoint: Make a list field hidden programmatically

I'm trying to hide the "Title" field in a list.
This doesn't seem to work:
SPList myList;
...
SPField titleField = myList.Fields.GetField("Title");
//titleField.PushChangesToLists = true; <-- doesn't seem to make a difference
titleField.ShowInEditForm = false;
titleField.ShowInDisplayForm = false;
titleField.ShowInNewForm = false;
titleField.Update();
//myList.Update(); <-- make no difference
What am I doing wrong?
Try this:
field.Hidden = true;
field.Update();
None of the above examples of setting Hidden true will work unless CanToggleHidden has a value of true. The problem is, CanToggleHidden only has a Get, not a Set, so you have to perform a radical "SharePoint programming gymnastics stunt" using reflection to first flip CanToggleHidden from false to true. Once you have done that, you can change Hidden to true (or back to false). There are plenty of examples out on the web (although not all of them are written correctly). If needed, I can probably dig up a PowerShell example that works.
if(field.CanToggleHidden) {
field.Hidden = false;
}
else
{
// display an error message or write to your favorite logging location
// explaining that there is no hope of changing the value of Hidden until
// CanToggleHidden changes to TRUE first.
}
Make sure you are grabbing a new SPWeb instance.
using (SPSite site = new SPSite(webUrl))
{
using (SPWeb web = site.OpenWeb())
{
try
{
//... Get SPList ...
}
}
}
I believe visibility of fields in lists are controlled by the default view that the user "gets". Don't you want to modify the view? I know you can get the Views for a list, as well as the default view.
I'm just spit-balling here...
There is a price you pay when you use Hidden property.
It's been discovered that setting a column hidden will remove the ability to delete it via code.
try this one this will work...
Title field is named as LinkTitle...
other fields can be hidden in the same way.
SPView view = list.DefaultView;
if(view.ViewFields.Exists("LinkTitle"))
{
view.ViewFields.Delete("LinkTitle");
view.Update();
}
The solution above is for hiding the field everywhere. It will also be hidden in the column overview of your list.
If you only want to hide the field in a particular list. Or if you still to manipulate the field (set back to visible) by using the list settings page. You need to set the "Hidden" property of the field in the "FieldLinks" property of the list.
myList.FieldLinks["SomeField"].Hidden = true;
