Hello Ling,

Sorry for the long overdue reply. Are you using by any chance the
dynamic proxy mode? It looks like it does not work yet well with the
SL (hope to get that fixed for 1.0). Could you in the meantime switch
to the lazy pojos?

[Ling Xu]

Hi George,

I have fixed the problem, you were right. I wish the online instruction/tutorial could be clearer, there are also some mistakes.

Thanks for the reply,

Ling

[George Georgovassilis]

Hello Ling,

In the meantime we released 1.0 which does contain support for the
dynamic proxy mode, so you might want to give it a try - but please be
advised that GWT itself makes using that hard, so you might want to read
the corresponding chapter in the SL documentation and evaluate the risks
before you switch to that.

The SL is a community driven project which lives from contributions of
its members; thus, if you have any concrete suggestions of how to
correct and improve the documentation please let us know.

Best regards,
G.
