Hi,
To debug a remote server you have to :
- start DevMode on your localhost,
- connect to your remote server with the normal url
- add gwt.codesvr=localhost:9997 parameter to the url where 9997 is the
port on witch DevMode is listening
As exemple if you have your app running on
getOffsetHeight() of an element which *display* property was set to *none*will
always return 0

You can either keep a reference to ctx2 and call persist() after the

you passed as an argument to edit(), so it's == ctx2).
Or you can enqueue the

Yes, you can control. In your RequestFactory fire operation, override
the OnConstraintViolation method in the receiver, like below.

Use firebug to analyze your problem.
If it's your display property then change this by
widget.getElement().getStyle().setDisplay(Display.BLOCK) (can be
little different).
By default the Display property is set to auto so if you aren't

The problem is that I call getOffsetHeight/Width on a panel which belongs
to a widget which has display property set to none. The display property is
set to none because that widget is not currently displayed by the

Hello,
I have got some Question concerning Serialization and persistence.
At First I have got a GWT project with Client code and a Servlet to
communicate with
my EJB Project.
In the EJB project there are some Persistent Entitie Classes with
references among each other and beans to manage them.
getOffsetHeight/Width only returns a value other than 0 if the element has
been successfully rendered by the browser (possibly including elements that
have visibility:hidden css).
When you call DeckLayoutPanel.setWidget(w) the DeckLayoutPanel schedules a
layout command which will be executed
You don't need getOffsetHeight to achieve what you want. There are two
solutions:
1. Use LayoutPanel instead of DockLayoutPanel. LayoutPanel allows you
to add two widgets that occupy the same space. If you don't specify
the position of each child widget, each child widget will occupy the
entire
I have the following hierarchy
User (entity)
- ListMember getMembers()
- ListProblem getProblems()
Member (value)
- User getUser()
Now, if I fetch a User using with(... members, members.user.problems),
I'm getting the problems only for the last member in the list. I verified
in the debugger
If you use GWT-RPC every class that goes over the wire has to implement
Serializable and must have a default constructor. Depending on your setup
it can occur that the RemoteServiceServlet from GWT does not find the
serialization policy file. So you should check your server logs to see if
