Hi Robert,
Working with osgIntrospection we have realized that
there is a problem with some methods (setName and addChild).
For example, if you create a Node and after that you call setName,
there isn't problems in the call.. but if you create a Group and then
you call the same method then crash.
The problem with the method addChild is similar. If you call it from
an instance of Group works perfectly but if you try to call it from
PositionAttitudeTransfom then it doesn't crash but the method doesn't
adds any child.
We are now working in a osgJava implementation, following the same
ideas of osgPython. Miguel(osgPython) and me have been debugging
and we have created a simple example in C++ showing the problem.
I would like to talk with Jose Luís(osgLua) to know if he finds the same
problem.
Notes:
- You can find attached the example and the line to compile it is
in the first line of the file ;).
- The example has been tested against osg 2.0 and with svn
version r7033 (few hours ago) and fails on both.
Rafa.
