Cannot find some specific classes (problems removing components) [message #84596]

Hi!

I've read some emails describing this same problem.
When deleting an component from the diagram, also deletes the respective
view and semantic. If there's any links from/to this component, the
respective view is also deleted, but the semantic stays.

I´ve read something about editing the NotationViewDependentsAdvice and
XXXEditHelper classes but I'm not finding them in the project.

I hope there's someone who can help me.

Thanks, anyway!

^^

Do it in the EditHelper corresponding to the semantic element you are
removing:

/**
* Gets a command to destroy the connections incident to this block
*/
protected ICommand getDestroyDependentsCommand(
DestroyDependentsRequest request) {
End end = (End) request.getElementToDestroy();

Set ret = new HashSet();
ret.addAll(end.getOutgoingConnections());
ret.addAll(end.getIncomingConnections());

return request.getDestroyDependentsCommand(ret);
}

Hi, Vlad!

I´ve tried this and i've included this method in one EditHelper but,
when debugging, this method is never called.

What can I do?

I tried to find the NotationViewDependentsAdvice, as I've read in some
emails, but it dont exists in the project.

thanks!

I remember having the same problem with the generated code.

In the generated XXXBaseEditHelper remove this code:

/**
* @generated
*/
protected ICommand getDestroyElementCommand(DestroyElementRequest req) {
return null;
}

The implementation in AbstractEditHelper is responsible for calling
getDestroyDependentsCommand().

Thank you Vlad!! it worked =)

but it seems that this method overrides a method on the superclass.
deleting it make the thing works, ok, but what should i return, if i
wanted to put an "generated NOT" instead of deleting it?

thanks again!!
