Select bean, component is red-marked in "Java Beans" pane. [message #89402]

Hi,

I want to add my panel to cardlayout panel. I click choose bean, find my
bean and click container pane in "Java Beans". Now it generates code
alright, even makes a getter. But somehow it always marks my bean with
little red icon (white cross in red background). Now did I miss something?
Something got wrong with the code? What does this icon mean?

My best regards,
Vladas

Hover over the bean and tell us what the error is.

Also see if there are errors in the .log file.

The hover is on the graphical bean, from the JavaBeans tree, select the
bean and look down in the status line.

Hi,

It's java.lang.NullPointerException(null). I failed to find a log file
anywhere.

Thank you for helping me,

Ok, first please append as a file the class that fails. Maybe we can see
if there is some syntax kind of error that we should be handling?

Second, attach the config info from Help->About Eclipse->Configuration.
This will tell us what you configuration is.

Sorry if code is messed up. This is under development. BridgePage tries to
put BridgePropertyPane and PortPropertyPane into cardlayout JPanel.

Hmm this is strange. "Java Beans" show switchPane has children
"(portPropertyPane)" and "bridgePropertyPane". Both marked with red icon. If
I add this line into source:

switchPane.add(new JPanel(), "test");

"Java Beans" does not show it as child.

Thanks!
Vladas

You're code in QuerySelectedSetting.getSetting() is throwing the
NullPointerException. Because of that we can't instantiate your
PortPropertyPane. That is why there is red-X on the PortPropertyPane, we
couldn't create one of them.
