Hi Martin,
myContent is the id of the StatelessAjaxLazyLoadPanel which contains a
constant
private static final String LAZY_LOAD_COMPONENT_ID = "content";
which is used in getLazyLoadComponent(String markupId). 'myContent'
contains the lazy load component 'content'.
StatelessAjaxLazyLoadComponent is added to a WebMarkupContainer which
itself is added to MyPage.
If you look at the source of AjaxLazyLoadPanel the 'content' (added in
onBeforeRender) is replaced in the respond method of the Behavior. Could
that be the reason why it is not a container?
Regards,
Karsten

In the StatelessAjaxLazyLoadPanel I'm using this Behavior instead of the
usual AbstractDefaultAjaxBehavior
/// My Page ///
onInitialize()
{
add( new StatelessAjaxLazyLoadPanel("**myContent")
Here we see "myContent" id.
{
private static final long serialVersionUID = 1L;
@Override
public Component getLazyLoadComponent( String markupId )
{
return new MyContentPanel( markupId );
}
@Override
public PageParameters getPageParameters()
{
return pageParameters;
}
} );
}
/// MyContentPanel ///
Form form = new Form("myForm");
form.add( new DropDownChoice<Enum>("**enumChoice"));
add(form);
java.lang.**IllegalArgumentException: Component is not a container and so
does not contain the path myForm:enumChoice:
[Component id = content]
Here it complains about "content". What is the relation between 'myContent'
and 'content' component ?
Which component adds the StatelessAjaxLazyLoadPanel ?
at org.apache.wicket.Component.**get(Component.java:4500)
Put a breakpoint here and see what is in the context. What is 'this', what
in its 'children' member field.
'myForm' has children with 'enumChoice' inside, then 'enumChoce' becomes
'this and you need to see how to get to the lazy load panel and its lazy
load component.
at org.apache.wicket.**MarkupContainer.get(**
MarkupContainer.java:354)
at org.apache.wicket.**MarkupContainer.get(**MarkupContainer.java:354)
at org.apache.wicket.**MarkupContainer.get(**MarkupContainer.java:354)

at org.apache.wicket.**MarkupContainer.get(**MarkupContainer.java:354)
at org.apache.wicket.**MarkupContainer.get(**MarkupContainer.java:354)
Would that be sufficient?
Thanks,
Karsten

Hi guys,
I still have no clue. Any suggestions? A work-around would also be much
appreciated. I need to stay stateless but I definetely need this lazy
loading as I have to wait for a soap response every 10 mins and for user
experience issues need to display some loading component/icon as provided
by AjaxLazyLoadPanel.
Thanks,
Karsten

Hi,
I'm trying to use the functionality of an AjaxLazyLoadPanel in a
stateless page but this doesn't seem to work as the injected content is
not
a container and the following exception is thrown:
java.lang.****IllegalArgumentException: Component is not a container
and
so does not contain the path componentid:****containedcomponentid:
[Component id = content]
at org.apache.wicket.Component.****get(Component.java:4500)
at org.apache.wicket.****MarkupContainer.get(**
MarkupContainer.java:354)
I wrote a StatelessAbstractDefaultAjaxBe****havior overriding
geCallbackUrl which I use in my StatelessAjaxLazyLoadPanel.
This doesn't seem to be the way. Anyone have any hints?
Thanks,
Karsten
