B4J Question Call new form

[chrjak]

Hey guys.
I started to try B4J 6 minutes ago and i didnn't find a tutorial for calling another form. i get a null pointer exception with my try.
Can someone help me pls?

Regards

You probably didn't initialize the second form.

Example of a second modal dialog: http://www.b4x.com/android/forum/threads/modal-dialogs.34656/

Example of two forms:

Sub AppStart (Form1 As Form, Args() As String)
   MainForm = Form1
   MainForm.Show
   
   Dim frm2 As Form
   frm2.Initialize("frm2", 400, 400)
   frm2.Show
End Sub
