AjaxTabbedPanel, AjaxLazyLoadPanel and back button

[Rodrigo De Castro]

Hey,

I've been using AjaxTabbedPanel successfully, but ran into the following
problem today:

1. Load page that has multiple tabs
2. Click on the second tab
3. Click on link on the tab panel that takes me to another page
4. Press back button

It fails with the following error:

WicketMessage: component
tabpanel:mytabpanel:panel:general_workflow_panel:graph_container not found
on page

The container (graph_container) is an AjaxLazyLoadPanel. If I don't load it
lazyly, it works fine. Is this a known bug? Or maybe I am not using
AjaxLazyLoadPanel properly? Let me know if you need more information.

AjaxLazyLoadPanel code:
        graphContainer = new AjaxLazyLoadPanel("graph_container") {
            @Override
            public Component getLazyLoadComponent(String markupId) {
                return new ChartPanel(markupId, new ChartModel());
            }
        };

This is where the panel is inserted:
<div style="float: left;" wicket:id="graph_container"></div>

And panel (ChartPanel) html:
<wicket:panel>
<div style="float: left; width: 650px; margin-top: 10px;"
wicket:id="graph_container">
    <img wicket:id="workflow_trend"></img>
</div>
</wicket:panel>

Thanks,
Rodrigo
