However now the designer is not drawing the UI anymore correctly, the only thing is shown is the outlined of the marked control. So my question, how can I solve the problem? I use jBuilder 2006 Foundation. Thanks in advance.

You can try by simplifying your UI code. Move some of your controls in separate classes. If I have a panel with lots of controls I create new class that descends from JPanel and move all related stuff there. Later on my bigger form I use that class. Also another approach is to try to comment parts of your code and then uncomment them one by one until designer crashes again. This will help you to see which code in your program triggers the error.

Back to top Doychin Bondzhev Guest Posted: Fri Mar 02, 2007 5:48 pm    Post subject: Re: UI is not displayed in jBuilder Designer JBuilder 2007 is based on Eclipse and uses for Swing design the Visual Editor from Eclipse project. Because of that use of Eclipse the project structure is different and also the way code for visual controls is handled differently. Can you try something else: Create a base class that descends from JInternalFrame. Put into this class all code that must be there for JInternalFrame to work. Make your class that descends from JInternalFrame to descend from this new class. For design you can change the base class to JFrame and then change it back to JInternalFrame when you make deployment build. Another option is to try to load your form into NetBeans 5.5 swing designer. Doychin pelle23 wrote: Quote: Doychin Bondzhev <doychin@dsoft-bg.com> wrote: There is one update for 2006.

Is it possible to get a bug fixed by borland when using the free foundation version? Should I try to download the jBuilder2007. Can somebody who has installed 2007 already try to force my problem, to see if it is fixed there?
