I've got an issue where I made a formpanel in the Ext designer, but when I export it, only the first field is visible. Seems that something is going wrong when the ExtJS code is generated. I also attempted to recreate the issue with a separate test project, but was unable to. Heck, I'll post that (project.xds), too.
Initially, I thought this bug was related to the post by froamer, but maybe not. Sure seems similar, though.
