Board index » jbuilder » UI is not displayed in jBuilder Designer

jbuilder19
Hello,
in my application I've created a quite complex UI derived from
jInternalFrame with 4 splitpanes, toolbars a lot
of buttons and jtabels...and so on ...
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.

There seems to be a problem with the designer, or what does this mean?
Is there an "unknown component" in my project (unknown source) or something?
 

{smallsort}

Unknown source means that the debug information was removed from classes
so JVM can't tell you where exactly in the source code this exception
was thrown.
In this case I suspect there is something wrong with JBuilder designer.

I need urgently to implement some bugfixes and cr's into
my application, depending on the use of the designer.
 

In such case I usually try to eliminate the code in my UI that causes
the error.
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.

The designer of jbuilder2006 is not able to show even this simple control.
I changed the superclass to JFrame and it was ok.
I think there is a major problem of the designer in version 2006 with JInternalFrame.
I have that problem since I've mirgrated to 2006 last month and can't solve it.
Is there somebody that can commit my experiences?
What can I do? (I don't want to go back to 2005)
There are any patches for jb2006?
 

There is one update for 2006. You can download it from Java Developers
section in CodeGear web site.

In the meantime I played and changed the superclass in my production- project to JFrame too and the UI is displayed correctly.
But I really need the JInternalFrame (MDI) functionallity.
It is also not possibble to change to JFrame, edit the UI and change back to JInternalFrame and complie, because there are to many lines to change if I do that.
What can I do now.
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?
 

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.
