I want to use the DefaultFromTemplate method on the PX.Objects.PM.ProjectEntry graph, but it is protected. (C#.net)
Is there a way I can make this public or extend the graph maybe. Or do I have to copy the code into my own class?
cheers
At this stage I'm just inheriting the project entry graph and calling it through a public method. cheers

I would like to override the bql query which is present in the appaymentlist dataview. shown in the screen shot below.
when i try to override appaymentlist in graph extension, I am unable to implement if() statement because of private "Cleared" field defined in the base graph.
My question are
How do I implement if() condition statement in the PXOverride dataview.
If I omit if() condition in pxoverride , will the base appaymentlist() implement if() condition statements. I mean , will the override "appamentlist" merges with the base "appaymentlist()"
What is the best way to override to implement such scenario?
any suggestions would be helpful.
You can't override a private field so what you need to do is:
Locate every location where the private field is used.
Copy paste/override all these location in your customization.
Sometimes these locations can be private too. In that case you need to find every location that calls into private elements and replace them.
Which series of XML namespaces will You use to serialize an object to XML using WCF?
For example, I have 4 types of Users (left to right) and they have data and references to members in my Users table. This way I could 1/2 have to remove functions and 2 methods because I do not have add/delete methods.
So to end up with code like
public void Save() {
microsoft.Office.Interop.Excel.Application, System.Application.Current.People, System.Runtime.Interop.Microsoft.Office.Interop.Outlook.Application,
Microsoft.Office.Interop.Outlook.Application,
Microsoft.Office.Interop.Excel.Application,
Microsoft.Office.Interop.Excel.Application,
Microsoft.Office.Interop.Outlook.
Microsoft.Office.Interop.Outlook,
Microsoft.Office.Interop.Contact,
Microsoft.Office.Interop.Outlook.
//General methods
}
It makes sense to me for someone to add the notes this method requires but that would allow me to have 2 methods.
Save a new class and create the form to save the new class
Write at least one file, Save or Open for reading?
Add a button about saving the file but then the form with some properties that the functionality should be saved to?
Is this the same? Or is there a better way?
Thanks!
i am using jaxb to generate code from an xsd.
The generated code contains a lot of annotations; for classes and fields.
I am trying to use com.sun.tools.internal.xjc.Plugin to modify the generated code.
In the plugin run() method we are given an Outline class from which we can get ClassOutline. ClassOutline has an JDefinedClass final member which has the info about actual class which will be generated.
If i want to add anything, there are apis in JDefinedClass which can be used. But if i want to remove something, there is no way.
e.g. i cannot clear annotations, because the JDefinedClass.annotations() method returns an UnmodifiableCollection. so i cannot clear it or remove anything from it.
i tried to create another JDefinedClass by invoking the _class method but the ClassOutline.implClass variable is final, so i cannot set it.
how to get a JDefinedClass which does not have any annotations?
is there another phase of code generation which i can trap into to really control the generation of JDefinedClass?
The code model is, indeed mostly "write only". But, speaking of annotations, you have probably missed the methods like com.sun.codemodel.JDefinedClass.removeAnnotation(JAnnotationUse) and com.sun.codemodel.JMethod.removeAnnotation(JAnnotationUse) (implemented from com.sun.codemodel.JAnnotatable.removeAnnotation(JAnnotationUse)).
So they're there. You can remove annotations with the normal CodeModel API.
As I can see, you can also remove fields and methods from classes. So what exactly are you missing?
JDefinedClass.annotations() It return an unmodifiable collection object and you cannot modify them.
So work around for this, you can restrict annotation addition/deletion at class and field level before building JCodeModel.
You need to create a custom Jackson2Annotator class which extends Jackson2Annotator and override their methods according to your requirement.
Following are few methods which are being used for specific type of annotation property:
propertyOrder(OTB JsonPropertyOrder)
propertyInclusion(OTB JsonInclude)
propertyField(can be used for custom defined annotation at field level)
More you can discover by looking Jackson2Annotator class what fit into your need.
I am implementing my own RequiredRole attribute called RequiredAnyRole, whereby I pass in a list but the user only has to be in 1 of the roles. I have implemented my own method called HasAnyRole which simply queries based on .Any() instead of .All().
I have then overridden the Execute method to use my method rather than HasAllRoles. The problem is im not sure what the method: AssertRequiredRoles is doing? It doesn't seem to be called?
Should I override that to use .Any() rather then .All() too? Here is the original code:
https://github.com/ServiceStack/ServiceStack/blob/82241fc96e187d12f9db2556aea37cf327813adc/src/ServiceStack.ServiceInterface/RequiredRoleAttribute.cs
AssertRequiredRoles is a static helper method that's can be used by other plugins like RequestLogsService to ensure access is only granted to users with the required roles. It's not called when used as a normal attribute filter.
Once you override Execute you retain full control of what gets executed, so you only need to override what you need.
I was under the impression that Force.com eliminated the necessity of object-relational mapping.
I can't create a an object that extends a custom object like this:
class Program extends Program__C() { public Program() { super(); } }
So to "add a method to the Program__c() object" I have been doing this:
class Program {
Program__c program;
public Program() {
program = new Program__c();
}
}
But then this leads to the same ERM problems that I thought Force was supposed to eliminate by virtue of the intercourse between APEX and the DB.
Is there any way to extend custom objects, or at least add methods to custom objects, in APEX? Am I incorrect in that developers don't have to do ORM?
Thank you,

As far as I know (and I'm pretty certain), there is no way to extend custom objects in the manner you wish.
What you're doing seems to be a reasonable solution to the problem.
You don't have to do ORM in the sense that any objects and fields you have in your DB are already accessible in your code with no extra effort. However, you can't do much (if anything) to affect your schema programmatically in your code. You're kinda stuck with it.
Hope this helps!
