B4J Question MainForm.RootPane.LoadLayout("frmMAIN") 'Load the layout file.

[claudio3g]

Hi all,
I use B4J version 5.90 and I'm getting crazy with this, all seems to be ok, I see the layout file in file manager BUT I always get this error:
java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast to java.lang.Class

These are the lines of code I'm working on:

#Region Project Attributes
#MainFormWidth: 600
#MainFormHeight: 400
#AdditionalJar: jtds-1.3.1.jar
#End Region

Sub Process_Globals
Private fx As JFX
Private MainForm As Form
Private Sql1 As SQL
Private Url As String
Private Driver As String
Private txtId As TextField
Private txtValue As TextField
Private btnUpdate As Button
Private tbView1 As TableView
End Sub

Sub AppStart (Form1 As Form, Args() As String)
MainForm = Form1
MainForm.SetFormStyle("UNIFIED")
MainForm.RootPane.LoadLayout("frmMAIN") 'Load the layout file.
MainForm.Title = "Stampe controllo produzione"
MainForm.Show

... many lines of code ...

End Sub

I'm new with B4J and Java, is there someone who can explain where is my error?

Bye

Claudio

I did a test with code and its seems ok. Maybe the problem is layout file. Try create a new layout file.

Sorry, this was my first post
Thank you for your explaination.

@Eme Fibonacci :
Great! It's solved. The problem was the layout file. I created a new one and it worked even if I didn't understand why there was the error, I redid it the same.
Thank you very much.
