Hi

i Want to extend the VE palette with a custom one to contain my own
beans. I wrote a BeanInfo class for my Beans and configured them in the
plugin.xml file.

Whe i test the palette, my beans are shown in the custom palette but the
propertydescriptor from the BeanInfo class are not applied.

Can somenone tell me what went wrong?

Thanks for an answer.

Couple of things:

1) First, don't use the same package for MyPanelBeanInfo as for MyPanel.
Even though that should work, it causes other problems. Put them in a
different package.

2) In the <searchpath package="..." the package should be the package
that MyPanelBeanInfo is in. Also, MyPanelBeanInfo must be in the
beanInfo.jar, which should be a separate jar from where MyPanel is in.

3) Are you running a deployed plugin (i.e all built with beanInfo.jar in
the plugin root directory) or are you trying to do this from a
development environment? In development, unless you use the proxy.jars
file to point to the bin output directory where you have the beanInfo
being built into at development time it won't be able to find the
MyPanelBeanInfo.

4) Also what is in the override file for MyPanel?

After these are taken care you'll need to see if there are any .log
errors and fix those, and then finally you'll need to do some debugging
to see if the search path, classpath are set up correctly for the
beaninfo and if it returns that it found it.

Hi

I fugured out the problem. The classpath container was wrong and so the
beaninfo classes where not found. I put the beaininfo classes now in
another package.

The overrides directory is currently empty because i do not realy know
how define them. Is there any documentation on how to create override files.

My goal is to extend the swing components with an interface that defines
specific attribute. a user for example. for this user attribute i
want to writ a custom cell editor. how is this done.

thanks bakito
