Serialization Update

Hi,


So, when running the serializer, GWT will produce errors:

[ERROR] [web_final] - Errors in 'file:/C:/dev/Java/CS%20460%20Project/Web_Final/src/cs460/webdnd/client/utilities/serialization/serializer.java'
 [ERROR] [web_final] - Line 24: No source code is available for type java.io.ByteArrayOutputStream; did you forget to inherit a required module?
 [ERROR] [web_final] - Line 25: No source code is available for type java.io.ObjectOutputStream; did you forget to inherit a required module?
 [ERROR] [web_final] - Line 39: No source code is available for type java.io.InputStream; did you forget to inherit a required module?
 [ERROR] [web_final] - Line 39: No source code is available for type java.io.ByteArrayInputStream; did you forget to inherit a required module?

 [ERROR] [web_final] - Line 47: No source code is available for type java.lang.ClassNotFoundException; did you forget to inherit a required module?


In response to this, Nialls took over serialization/deserialization using code he found online.  This code produces tons of errors, as he writes here: http://niallsc.blogspot.com/2012/03/canvas-serialization-status-failed.html.


However, this misses something--my serializer worked.  It produces this output (if you add a print statement):

Now, this looks to me like taking a canvas and serializing it (and I can get a canvas back, deserializing it).  I'm not sure what the problem is with Nialls's code, but mine seemed to work.

I feel somewhat accused, but I submit the above as evidence that the code I wrote is working properly.  There were limited tests with more complex canvases (nested, with content, etc.) that were conducted some time ago, successfully.  It is possible that there is some new problem (like maybe a certain component can't be serialized) which can be solved in the same way as the canvas's serialization was.

Now, I don't know what to say.  Maybe there's something subtle going on that I'm missing.  Maybe I don't know what I'm talking about.  Maybe there's a fundamental flaw in this that really will somehow prevent this from working.  I welcome explanations.

Regardless, I think it's a good idea to meet Sunday as Nialls suggested to work this out.  For the good of the project, it needs to be solved sooner rather than later--and I had already thought it was solved.

Thanks,
Ian
