We are working on a project that uses GWT-Ext, and want to move to GXT because of the recent ExtJS license change to GPL and the following abandon of the main developer. The new GXT/ExtJS license fee is acceptable for us, as GXT is going to be officialy supported.
But I am having too many problems to get started with GXT.
First of all, there is a lack of documentation about the requirements:
Which GWT version is needed? GWT 1.4? GWT 1.5M1? GWT 1.5M2? Maybe GWT from the SVN trunk? The GXT page (or Ext GWT as the product is named) doesn't give any information, neither the release notes. Since the release information talks about using GWT 1.5 features, I suppose I have to use an unreleased 1.5 version. Furthermore, there is no information about which JDK has to be used (only found in the forums).
Many people in this forum talk about having downloaded the code from the SVN repository. The question is, where is that repository? The website doesn't give any information although there is a page about licensing and open source, so, which is the repository URL?
Yes, there needs to be better documentation. You can take look at the new documentation center at http://extjs.com/gxt/helpcenter. It includes system requirements and a project setup guide. The help content is also available as a Eclipse plugin.
