i created a plugin for ext 2.0, it doesn't really have everything in it like samples and stuff, but it basically works in terms of copying ext files into a new project and integrating with content assist. i followed directions here: http://aptana.com/dev/index.php/Adding_support_for_a_new_Ajax_library i do have a slight issue in that when i copy the unzipped plugin folder into the aptana plugins folder it works as expected, but if i zip the folder (with the contents at the root) and copy the resultant jar file into the plugins directory, aptana recognizes the plugin in the sense that when i create a new ajax project "Ext 2.0" shows up as an option, but when i select it and click "finish" it returns right away and fails to copy the ext files into the created project. can anyone with experience provide some direction on where i may have went wrong? thanks, tony.
