Upgrading and the mess it brings

Today i tried to update my GWT version to 1.6 m2 (a beta version), seems like this was not such a great plan. Cypal Studio doesn’t support that version yet. yeah, I should start by looking that up and not finding it out half way in.
After compiling I saw my loginbox pop up and I thought all was well. So I started to login, and this is where the mess started. The new version broke my RPC call’s. Thinking it would not be easy to fix that (well the fix was easy as mostly but finding out how to do it was not) I went back to the ‘old’ GWT version (1.5.3) and try to login again. But apparently running the project under the new GWT 1.6 changed some thing in my project files. Still got runtime error’s on the RPC call’s. Knowing not so much about the way those calls worked (the where copied from the gwt-ext project) it took me quite a long time to figure out what was going wrong. By the end of the day I finally noticed the 3 lines missing from tomcat’s web.xml file. I added them again and I was back @ the point I started this morning a gwt1.5.3 project :).
Ill just wait till Cypal studio and GWT bring out there final new versions.
