_extend48 - ring any bells?

Hi,

I've got a problem in production whereby our application home page
throws a :Unable to find component with id 'mainPanel' in
[MarkupContainer [Component id = _extend48]]

This only happens once or twice a week. We don't have any components
named '_extend48' or similar anywhere in the code. Whats odd is that
this page renders 99% of the time fine, but for the life of me I
cannot understand how this can happen.

Is the component id given a red herring? Any ideas on how I can find
out what causes this?

thanks

super panel:

	
1	<html>
2	    <body>
3	        <wicket:extend>
4	                        <div wicket:id="mainPanel"/>
5	        </wicket:extend>
6	    </body>
7	</html>


mainpanel:

the main panel can be one of 3 different panels depending on the
context of the request. However I'm 99.5% sure (looking at the logs)
its this panel:

1	<html>
2	
3	    <wicket:head>
4	    </wicket:head>
5	
6	    <body>
7	        <wicket:panel>

Would you show the html of this mainpanel and also its super panel?

Re: _extend48 - ring any bells?

Here's the code for the CompanyPage (the first panel)

public class CompanyPage extends DashboardMenuPage {
	
	public CompanyPage() {
		super(CompanySelected.dashboard);
		
		if (ContextUtil.get().getUser() instanceof ExternalUser) {
			TeamProject[] projs =
ContextUtil.get().getUser().getProjects().toArray(new TeamProject[0]);
			
			if (projs.length == 0) {
				User admin =
ServiceLocator.getUserService().getFirstAdmin(ContextUtil.get().getCompany());
				String body = getString("noworkspace.message.body");
				body = body.replace("{0}", admin.getEmail());
				setResponsePage(new
MessagePage(getString("noworkspace.message.title"), body));
			} else {
				setResponsePage(new ProjectPage(new
HibernateEntityModel<TeamProject>(projs[0])));
			}
			
			return;
		}
		
		// perhaps they have configured their look and feel not to have the dashboard
		// if not redirect to the All workspace page
		if (!ContextUtil.get().getCompany().getGeneralSettings().isShowMyDashboard())
{
			throw new RestartResponseException(new WorkspacesPage());
		}
		
    	add(new CompanyDashboardPanel("mainPanel"));
	}
	
    public CompanyPage(PageParameters params) {
    	super(CompanySelected.dashboard);
    	if (params.get(PostingLinkBuildingStrategy.POSTINGID) != null) {
	    	IModel<Posting> postingModel = new
HibernateEntityModel<Posting>(Posting.class,
params.getLong(PostingLinkBuildingStrategy.POSTINGID));
    		add(new PostingDetailPanel("mainPanel", postingModel));
    	} else {
    		add(new CompanyDashboardPanel("mainPanel"));
    	}
    }


}


The second depends on the context, so thats a lot fo code to copy and
paste . Something that looks wrong here is calling setResponsePage
directly in the constructor rather than using
RestartResponseException. However calling setResponsePage does seem to
work fine - could it cause this issue?

What could I look for here?
many thanks

Hi Jeremy,

> That is the id for the wicket extend tag in your markup

This might be a stupid question - but can I tell where in the page
this might be causing the problem from the _extend38? Is that the 38th
extend for example?
Any hints on how I can track this down?

thanks

Hi,

I've got a problem in production whereby our application home page
throws a :Unable to find component with id 'mainPanel' in
[MarkupContainer [Component id = _extend48]]

This only happens once or twice a week. We don't have any components
named '_extend48' or similar anywhere in the code. Whats odd is that
this page renders 99% of the time fine, but for the life of me I
cannot understand how this can happen.

Is the component id given a red herring? Any ideas on how I can find
out what causes this?

thanks
