currentcontroller = null

Classic Servoy

I wanted to resize my main form after login

function backupRestore_onOpen(event) {
	application.output("onopen")
	
	currentcontroller.getWindow().setSize(400,200)
}

currentcontroller returns null

Are you using Servoy 6?

currentcontroller is on that place not yet there
because you execute the onSolutionOpen method… there is no form then yet.
