ProjListProjTransDataContract object not initialized.

Stack trace

(C)\Classes\ProjListProjTransController\prePromptModifyContract - line 11
(C)\Classes\SrsReportRunController\startOperation - line 7
(C)\Classes\ProjListProjTransController\run - line 8
(C)\Classes\ProjListProjTransController\main - line 3
(C)\Classes\FormFunctionButtonControl\Clicked

I'm adding a button to a list page form that opens a ssrs report based on the selected value in the list page. There is an existing similar button on another list page so I basically copied all of the classes/menu items/tables and replaced certain info to work with the new button instead. I've went over it all many times and I can't seem to figure out why I am getting this error.

If I need to provide more information I can. Thanks in advance.

You see that the error is thrown at line 11 of ProjListProjTransController.prePromptModifyContract(), therefore go there and check what's going on.

If you copied this and it is report, check your report name in controller. It is common error when you copy report classes.

protected void prePromptModifyContract()

{

ProjTable projTable;

ProjListProjTransDataContract contract = this.parmReportContract().parmRdpContract() as ProjListProjTransDataContract;

super();

if (this.parmArgs() && (this.parmArgs().record() is ProjTable))

{

projTable = this.parmArgs().record();

contract.parmProjId(projTable.ProjId);

}

}

Line 11 is that last line of code. The code in this method is the exact same as the other controller class aside from names. Below is what the data contract class looks like.

class ProjListProjTransDataContract

{

ProjId projId;

}

[DataMemberAttribute]

public ProjId parmProjId(ProjId _projId = projId)

{

projId = _projId;

return projId;

}

If I comment out that line 11 code in the controller class the report opens with the button, but obviously doesn't fill in the selected project id.

That this.parmReportContract().parmRdpContract() as ProjListProjTransDataContract returns null can be caused by mean two things:

Either this.parmReportContract().parmRdpContract() returns null

Or it returns an object but it's not ProjListProjTransDataContract

Please debug your code to see which case it is.

Wondering if this has anything to do with it:

The report parameter form I copied the information from looks like this:

(notice the Project ID field has a dropdown to select the id from)

Where as the report parameter from that I am trying to use looks like this:

To fill in the parameters in this from you have to hit the select button first which then has this form pop up

After filling in the criteria information, clicking ok then fills in the parameter form.

So I'm wondering if this is the reason I'm getting these errors and if so is there a way to change the way my form/report works so it works more like the first form with the dropdown menu?
