Hi
I've bin working with Parsely for quite a bit now and encountert a little probem.

I have a entylist of different literature types and want so search for a specific titel
I added a label and button, but now i'm unsure of how to address th specific entrylist to call my search method

formControlFactory {
control {
Entrylist : search -> {
val c = new Composite(parent, SWT.NONE)
c.layout = new GridLayout(2, false)
val t = createText(c, SWT.BORDER)
val b = new Button(c, SWT.PUSH)
b.^text = "Search Titel"
b.addListener(SWT.MouseDown) [
MessageDialog.openInformation(c.shell, "Event", Entrylist.search(search))
//I just don't know, how i reference the Entrylist, the button and label are linked to.

]
return t
} target {
observeText
}
}
}

Dear Dominik

The current EObject can be accessed in the block with the getter getOwner (or simply "owner"). That will have to be casted to Entrylist if you really need the Entrylist properties.
Please keep in mind that in the release 2.0 (scheduled in June together with Photon) we might rename that getter to a more intuitive name. We could also change the semantics of the DSL so that the current EObject (already casted) is automatically made available in the block; if you think that would be a valuable feature, please open a bug.

Please let us know if this fixes your problem.
cheers
Lorenzo
