GWT usage of Document.get().getElementById("main") vs RootPanel.get("main")

2014-12-10 Thread Jugunu 
Hi , I am using GWT in my project and i came across this issue.. I have the 
container structure as below in my main html... If i try to access main 
directly with

RootPanel.get("main")

, i get an error "A widget that has an existing parent widget may not be 
added to the detach list".. It works fine, if i try to get "container", but 
any child element...(all in dev mode, it works fine in production)


  
  
  
  




I don't want to add all above n code now, say with HTMLPanel (its working, 
if i add one by one each HTMLPanel to container)

Now i tried another approach of using this DOM parsing and adding a node..

Document.get().getElementById(GwtCnst.PANL_MAIN).appendChild(mainCanvas.
getElement());


Please advise me on whether it will create a performance issue or any thing 
that i am missing.

Thanks
Jugunu

Re: IncompatibleRemoteServiceException & SerializationException Issue.....

2011-07-29 Thread Jugunu 
I am not getting it always, after doing a gwtcompile i am getting it
sometimes even in dev server... I tried to deploy it in tomcat after
creating a war, that time the response returns from handler, but
doesn't reach the async call back ..

Previously i was getting serialization error in Arraylist , but now i
am getting only this, not sure what changed...

Note: I am not extending IsSerializable but just extending all my
objects with java.io.Serializable...

IncompatibleRemoteServiceException & SerializationException Issue.....

2011-07-28 Thread Jugunu 
Hi GWT Group,

I am getting a IncompatibleRemoteServiceException  & serialization
exception... But i have extended my class with
java.io.Serializable...  Also i have observed that I am having
duplicate entry in the gwt.rpc file..one starting with"[L" and the
other without...  Can you give me some guidance to solve this issue?

UserInfo extends AResponse
