formHasMethod not checking for form extension methods

(0) ShareShare
ReportReport
Posted on by Axaptus 10

Hi !

I have the following form extension class:

[ExtensionOf(formStr(EcoResProductDetailsExtended))]
public final class EcoResProductDetailsExtended_Extension
{
    public Set myMethod()
    {
        Set mySet;


        return mySet;
    }

}

Then I want to evaluate if that method exists before call it:

 if (formHasMethod(_formRun, 'myMethod'))
 {
 	localSet= _formRun.myMethod();
 }


The formHasMethod return false. It isn't being able to evaluate the extension method. If I call myMethod() without checking for it before hand, it is executed correctly.

I'm trying to use MetadataSupport helper class but I'm not succeeding.

Does anyone have some clue about it?

Thanks!

    As Martin pointed, this does work in 8.0!

    I was told that formHasMethod() has got this capability in PU18.

    It is generally the same solution as was suggested on 15 Nov 2017 by Axaptus.

    Thanks Zain for your prompt answer.

    Yes, I've verified calling formHasMethod method for a standard form method and it worked well.

    The method is called from an event handler class wich is in the same model where the Extension class.

    I'm looking for some metadata helper yet. Any clue will be appreciated.

    Have you tried to check this condition for a default method name from original form? Does the condition work then?
