adding the following line did not change anything
renderers.current.unbindToElementId('renderercontainer');
and I do not know how to check the view id
Calling disconnect and connecting again would
indeed solve the problem but why would anyone
want to do that? I am already connected, all I want
to do is load some other data. You do not
connect/disconnect for every query you are going
to execute on database, so why do it here ?
Is there a paravievweb document I can read somewhere,
like the ITK or VTK books? That would help greatly.
Thank you,
Cagatay
