nimo stephan [http://community.jboss.org/people/nimo22] created the discussion "Eclipse org.eclipse.swt.SWTError: Item not added" To view the discussion, visit: http://community.jboss.org/message/567406#567406 -------------------------------------------------------------- I am using the actual RFTools Version and the actual Eclipse (Galileo) and get sporadically failures within my gui which is really annoying: Sporadically, I cannot select any items of my taskbar when eclipse is running and there are other strange bugs when running eclipse, such as not viewing sub-menus. After making an update to the actual rf-plugins, I get this error which prevents me from opening eclipse. !ENTRY org.eclipse.osgi 4 0 2010-10-20 14:48:36.745 !MESSAGE Application error !STACK 1

I cannot work with Eclipse anymore. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/567406#567406] Start a new discussion in JBoss Tools at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
