Hello,
in some cases i need to hide some connections in my editor but i cant get it going...
i tried the following:

SetRequest setRequest = new SetRequest(getEditingDomain(), editPartView, NotationPackage.eINSTANCE.getView_Visible() , new Boolean(false));
this.getViewer().getEditDomain().getCommandStack().execute(n ew ICommandProxy(new SetValueCommand(setRequest)));

this seems correct to me but it still doesnt change the value of "visible:" to false.

any idea how can i deal with my issue?

help would be greatly appreciated!!
best regards,
spyro

Do you only need to hide connections or also the Editparts to that connections?

Because if you hide the nodes the connections in between or without source/target get hidden too.

Unfortunatelly I never tried your approach but I think I managed to hide connections (and edit Parts) like this:

new AbstractEmfOperation(editingDomain, title, options){

doExecute(monitor) {

//call getNotationView().setVisible(false)

}

}
However I only called this on connections that would have been hidden anyway, so I am not sure if this would hide ONLY connections without the according edit parts.

thank you for the reply Artur... my problem was that i could hide the nodes but then the connections were still there if either target or source node wasnt hidden. i fixed my error - i realized that i was asking the command stack to execute 2 concurrent commands which seems to be wrong.
i will try your way too .. is always good to have alternatives Smile

thank you and regards,
