Hi greatness, The fact that you're using the Long type (which is now correctly emulated in GWT 1.5) tells me that it could be one of the causes of the migration issues you've been facing.
Specifically, check out the notes about using the emulated Long type in the Java compatibility docs linked below: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=DevGuideJavaCompatibility The thing to watch out for is that your code isn't accessing long types in JSNI code, which will break the emulation and likely crash in places where you code is still expecting a long. I have an even stronger suspicion that this is the main cause of the problem because you mentioned that your application works in hosted mode but breaks when deployed in web mode You also mentioned that you changed longs to doubles in your code during the migration but issues still occurred. It's possible that there is more than one issue getting in the way of your migration, although it will be hard to track since the issues you described aren't typical. Here is what I recommend trying: either change Long to double, especially if using Long isn't necessary (i.e. you could do with 32-bit representations). Next, make sure your code is complying with every other step required while migrating from GWT 1.4 to 1.5 in the documentation linked below: http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&s=google-web-toolkit-doc-1-5&t=ReleaseNotes_1_5_UpgradeGuide Finally, try building and running your application once more. If it still doesn't work, let us know the exact error message you're seeing. Hope that helps, -Sumit Chandel On Wed, Mar 25, 2009 at 4:03 PM, greatness <[email protected]> wrote: > > Hi, > Not changing the code at all, migrating to GWT 1.5.3 causes that > problem.
