Description nlstefan 2005-09-14 08:23:36 UTC 
I am currently working on a midlet and i am building my GUI with the MIDP visual
design component, however everytime when i close NetBeans, the visual designer
crashes. the Inspector window says i don't have any screens in my project. 

when i open the flow design, it gives the following error code:

Annotation: Exception occurred in Request Processor

i have also added some custom components to the visual designer and somehow i
have the feeling that is has some trouble with that.
Comment 1 nlstefan 2005-09-15 09:01:09 UTC 
i have some more information about this bug in netbeans IDE.

for my midlet i made a class that extends the javax.microedition.lcdui.List class.
i added this class to the component palette so that i could easilly use my own
List class. The problem is that when you use your own "custom components". the
visual designer cant find the appropriate class in the classpath. when i changed
the class to a normal List in the .mvd file the problem was solved and the
visual designer worked.
Comment 2 David Kaspar 2005-09-19 13:14:44 UTC 
The problem was that List Element expected to be attached to a List component.

Fixed. See next mobility q-build.
