I am evaluating Window Builder/ Swign Designer for a client. I am running Eclipse Helios 32 bit SP1, but on a 64 bit machine running Windows 7. I followed the instructions for installing WindowBuilder Pro from the update site and I am using all default setting including L&F.I have not had the positive experience that I was expecting given what I have been reading about WindowBuilder. WindowBuilder would not parse the GUI that I had hand coded, even though there were no compilation errors or warnings and the code ran fine, so I started again from scratch. This worked until I made a hand written method that returned a configured text panel (code that was copied straight from the Swing Tutorial for JTabbedPane). At that point, when going to the design window, a parse error was thrown saying that a componet has "different parents for a double association." Again, there are no compilation errors in the hand-coded code and the application runs fine. I commented out the new code and was able to parse again. Now I have just defined a JPanel and when changing its variable name to "sectionPanel" in the properties dialog I got a message saying that WindowBuilder encountered an error and needed to close. After reparsing the code, the desiger opened again and the variable was renamed.
I am truely surprised at the number of problems and crashes I am having. (I have submitted these problem throught the program.) I keep hoping that the problems are related to the transition to Google, or Helios, and that updates will fix them soon, but I keep checking and there are none. Am I doing something wrong? Are others experiencing this?
