Hi Obsega - my company has bought the licenses for Ext-GWT 1.0 - which is not compatible with GWT2.0. To upgrade to GWT2.0, we'd have to upgrade our ExtGWT licenses to ExtGWT3.0 - and since I am the only one using this toolkit now and need this upgrade only for the History functionality, I am not very optimistic if we'd be upgrading the ExtGWT licenses :-(
I know its annoying to ask questions about an older version - but I have no other option in this case. Anyone .. any clues what might be going on?? Thanks!
