Standalone form? [message #1777826]

Hi again ;)

I'm trying to create a form to edit an EMF model element

@Inject FormFactory formFactory;
@Inject AdapterFactoryEditingDomain eddom;

I've tried to manually instantiate:

FormDetailComposite x = new FormDetailComposite(activeShell, SWT.NONE);
x.init(alias, eddom);

Got a nullpointer at org.eclipse.emf.parsley.composite.AbstractDetailComposite.init(AbstractDetailComposite.java:59)

Also tried this way and got a nullpointer again:
FormDetailComposite formComposite =
formFactory.createFormDetailComposite(activeShell, SWT.NONE);
x.init(alias, eddom);

also tried to leave out the eddom...in init, which gives me another nullpointer: at org.eclipse.emf.parsley.composite.AbstractDetailComposite.init(AbstractDetailComposite.java:47)

Do you have any examples of how a form for a model element could be instantiated and displayed in RAP?

Thanks!
Ulrich

Hi Ulrich,
sorry for the late reply.

Did you create the view with Parsley ExecutableExtensionFactory? It seems that injected attributes are not properly initialized.
It' s automagically managed by parsley it your plugin has the Parsley nature and you define your view in the dsl.

Let me know if this reply helps you.

Hi Francesco.

Sorry I didn't ask the question correctly. I am trying to reuse some of your widgets, esp. the dual list box. Not sure if this is possible? I tried something like this, with the hope of opening just the dialog as a standalone widget (like a popup).

DetailFormBasedDialog x = new DetailFormBasedDialog(shell, "test", eobject, null);
x.create();
shell.open();
x.setBlockOnOpen(true);
x.open();

I understand that this poking around in Parsley's internals isn't intended, but if it works it would be quite nice (consistent widgets everywhere)

Thanks
Ulrich

Hi Ulrich,
you can of course use Parsley for your goal, as long as you don't create explicitly (using new) the instance of DetailFormBasedDialog.
Always let a factory do this.
Your code may do something like this for example:

	@Inject DialogFactory dialogFactory;
	@Inject AdapterFactoryEditingDomain eddom;

	private Mail mail;

			...
			DetailFormBasedDialog x = dialogFactory.createDetailFormBasedDialog(
						getSite().getShell(), "Modify Mail message", mail, eddom);
			x.create();
			x.setBlockOnOpen(true);
			x.open();

(I just tried this in the Parsley Mail RCP Example)

Let us know if this works for you
Vincenzo
