Toolbar throws: IllegalArgumentException

Original issue 1306 created by codenameone on 2015-01-24T06:26:11.000Z:

What steps will reproduce the problem?

1. Add a Toolbar to a Form
2. Set a back command to the toolbar: tb.addCommandToLeftBar(cmdBack);
3. Add menu commands to the toolbar: tb.addCommandToOverflowMenu(cmd1);
4. Run the application in the simulator
5. Navigate to a form other than the original to which the toobar was added
6. Select the menu command.

What is the expected output? What do you see instead?
I expect the dialog for the menu command to display items, but instead I get an exception.

What version of the product are you using? On what operating system?
The most current. Windows 7.

Please provide any additional information below.

I rearranged the way in which I am using this control, and since then, I have not seen the error reappear. Please close this issue.
