Roman,
I'm afraid I don't have time to study this problem you are having in great
detail, and the problems aren't obvious to me from the code that you posted.
I know that these type of errors can be very frustrating, so I will try to
provide you some details that can help you solve the problem on your own. :]
We know that you are dealing with a NoSuchElementException. When you look at
the Javadoc for this class you can see that it is thrown when you try to
access the next element in a Java Collection object using an Enumeration. We
can determine from the stack trace you posted that the type of Collection
throwing the error is a Vector. The stack trace also tells us that the
Vector is related to or contained in the GeometryInfoTab class.
Look at the source code for the GeometryInfoTab class. Try to determine
where the class is using a Vector object, and why. Look for a method in the
GeometryInfoTab class that accesses this Vector trough an Enumeration. When
you've isolated this code, try and determine why the Vector would be empty
in your implementation.
I'm not sure why you are having the other problem with the display of
Feature attributes. Let me read over your e-mail and send a question to the
mailing list about that in a different thread. In the meantime, you can work
on the other problem I talked about in the first part of the e-mail.

Hei Roman,
just on the first part:
how to use your own code with jump:
please have a look on th openjump.org wiki
you can
- add your plugins by changing JumpConfiguration.java or
OpenJUMPConfiguration.java
- use a properties file (xml)
- build your own plugin extension
http://openjump.org/wiki/show/Documentation
i personally prefer for the development the properties file (is also a
commandline option). But for the distribution a plugin-extension should
be used (see here the plugins you can download from sourceforge)
