i wrote a program to read data from json file to a tree, then manupulate
the data in the tree, currently i am working on displaying the data in a
grid panel(there will be further manipulation).

now the data can be correctly displayed on the gridpanel in the hosting
mode. but the build cann't went through to make it on the web mode.

the error is as follows:

Output will be written into
E:\eclipse-jee\workspace\com.jsk.ContextNote\build\gwtOutput\com.jsk.ContextNote.Note

There are a few posts on this topic. You should increase the gwt heap
size not the IDE heap size.

Hi simon

did you manage to resolve the problem? I kinda have the same one.
But I don't think this has anything to do with the heap space.
I believe there's a construct that is not understood by gwt compiler,
but I can't find out what.

Here is the error that I get :

Hi... perhaps your problem is that you're using java.util.TreeMap
somewhere, that implements Serializable. I think that Serializable is
not implemented by gwt 1.4.x....

Try to use another class...

I had this problem right now, fortunately I just made a few changes
before recompiling the stuff, so I could figure it out.

I have a frame Widget structure and a SimplePanel in it, which is
meant to contain the current working view of the application. A view
manager handles navigation and view presenting, by invoking setWidget
on the SimplePanel. First my Application module load code called
explicitly setWidget to present a Welcome page, to have something
there by default. I changed this, I wanted to present the Welcome page
by asking the view manager to present the view by the name
"Welcome" (they are stored in a HashMap). However, I forgot to
register the Welcome page by its name in the view manager, so the
execution would have resulted in something like nullpoinerexception.
At this point I got the compile time error quoted above. Then I
realized that I have this missing, and inserted the registering of the
Welcome view (they are registered in a static class initializer).
After that, it compiles and works fine.

So, somehow the GWT compiler detected that my SimplePanel would remain
without a Widget set.

I hope this helps.
