DockLayoutPanel does not render correctly in a view. about mvp4g HOT 7 CLOSED

Could this message help you 
http://groups.google.com/group/mvp4g/browse_thread/thread/8ced7f667001afe4?

I will look at it and let you know.

The problem is by default Mvp4g add the RootView to GWT RootPanel. LayoutPanel 
(like 
DockLayoutPanel) doesn't work well with RootPanel. 

A workaround for this issue is to not use the default entry point of Mvp4g but 
uses 
your own and have the following lines of codes:
   Mvp4gModule module = (Mvp4gModule)GWT.create( Mvp4gModule.class );
   module.createAndStartModule();
   RootLayoutPanel.get().add((Widget) module.getStartView());

I had actually tried the second part of that message :

Mvp4gModule module = (Mvp4gModule)GWT.create 
( Mvp4gModule.class ); 
     module.createAndStartModule(); 
     RootPanel.get().add((Widget) module.getStartView()); 

with no luck (after, of course, changing the .xml etc. to load from a module.

I just tried adding the constructor mentioned in the first. It failed to create 
the 
Element, but by just using the .add it seems to work. Of course, I'm not sure 
that 
what it's generating is perfect, but at least the data is being displayed!

public RootTemplateView(){
        RootLayoutPanel.get().add(dock);
        /*Element element=DOM.createDiv();
        element.setClassName("hidden");
        setElement(element);*/

    }

With your demo I tried your method and it worked. However, with my actual 
project I've 
found I need the RootLayoutPanel.get().add(dock) line.

I'm not sure what's different, apart from the fact that I have an 
DockLayoutPanel 
embedded in the main DockLayoutPanel (a similar configuration to the GWT E-Mail 
sample).

Your RootView extends LazyPanel, right? Could this be the problem?
A DeckPanel can only have a LayoutPanel as a parent, but in the case your view 
extends a LazyPanel, then the parent of the DeckPanel is a SimplePanel, that 
could 
explain why the DeckPanel is not displayed.

Could you try to have your view extends Composite instead of LazyPanel?

I only know Mvp4g at the usage level but I don't think it is a bug with Mvp4g 
itself.  I am using Mvp4g 1.1

In addition to using RootLayoutPanel (and <!DOCTYPE>) as pointed out by 
plcoirier (Jan 2, 2010), it seems that the start view and its chain have to be 
layouts ... below is what I got ...

MainView.ui.xml ...
    <g:DockLayoutPanel unit="PX">
        <g:north size="25">
            <g:HorizontalPanel>
                <g:cell width="1200" horizontalAlignment="ALIGN_RIGHT">
                    <g:MenuBar ui:field="menu" width="140px" animationEnabled="true" autoOpen="true">
                        <g:MenuItem ui:field="settingMenuItem">
                            <g:MenuBar vertical="true" animationEnabled="true">
                                <g:MenuItem ui:field="preferenceMenuItem"/>
                            </g:MenuBar>
                        </g:MenuItem>
                        <g:MenuItem ui:field="loginMenuItem"/>
                    </g:MenuBar>
                </g:cell>
            </g:HorizontalPanel>
        </g:north>
        <g:north size="30">
            <g:DecoratedTabBar ui:field="tabBar"/>
        </g:north>
        <g:center>
            <g:LayoutPanel ui:field="body"/>
        </g:center>
    </g:DockLayoutPanel>

ContentListView.ui.xml ... content of "body" above ...
    <g:DockLayoutPanel unit="PX">
        <g:north size="30">
            <g:SimplePanel>
                <g:Label>Header</g:Label>
            </g:SimplePanel>
        </g:north>
        <g:south size="30">
            <g:SimplePanel>
                <g:Label>Footer</g:Label>
            </g:SimplePanel>
        </g:south>
        <g:center>
            <g:SimplePanel>
                <g:Label>Body</g:Label>
            </g:SimplePanel>
        </g:center>
    </g:DockLayoutPanel>

I'm closing this bug since Mvp4g can be used with any kind of layout.
