Hi again
I am trying to add a Filechooser to my EMF Parsley Project
I've tried it like this

configurator {
		resourceURI {
			TreeformSaveableTreeFormView -> {
				val fc = new FileChooser(null, SWT.NONE);
				return URI.createFileURI(sd.open() as String);
			}
		}
	}

and hoped it would just open the dialog, but that's not the case.
So now I don't realy know how I should implement it.

Hi

do you get any specific error?
you pass null as the shell to file chooser I guess, is that supposed to work in FileChooser?

Note that this use case hasn't been taken into consideration at the moment.

I don't get any Error
null should work with the FileChooser, but even if i pass a new Shell i don't get any responses

By the way, where does FileChooser come from?
Note that you assign it to "fc" but then you call open on "sd"...

I've just tried with org.eclipse.swt.widgets.FileDialog:

configurator {
		resourceURI {
			TreeformSaveableTreeFormView -> {
				val fc = new FileDialog(site.shell, SWT.OPEN);
				val result = fc.open();
				return URI.createFileURI(result);
			}
		}
...

and this works out of the box, as expected: the first time you open the view the dialog shows up

That is the syntactic sugar from Xbase (the Java-like expression language the Parsley DSL is based on): it stands for getSite().getShell() : the code block is passed a paremeter "it" of the same type of the type before the arrow (in this example, TreeformSaveableTreeFormView), that can be used in the block. "it" can always be used as an implicit receiver (like "this"). Summarizing, "site.shell" is the short form of "it.getSite().getShell()" (and getSite() comes from the fact that a View has such a method).
