Try to use the "replaceWith" method on the dataTable component.
I'm attaching a piece of code where we use this method in (*another *but
similiar) situation where we need to replace the content of a modal window
when the selected line (of dataTable) is changed:
add(new AjaxLink<Campaign>("details")
{
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
selectedLine =
(Campaign)getParent().getDefaultModelObject();
ZoomCampaign tempZoomCampaign = new
ZoomCampaign("zoomCampaign", new PropertyModel<Campaign>(myModel,
"selectedLine"));
zoomCampaign.replaceWith(tempZoomCampaign);
zoomCampaign = tempZoomCampaign;
target.add(zoomCampaign);
zoomCampaign.show(target);
}
});
