I think I'm getting a bit further now - sorry to spam this list by the
way...
If I pass the breadCrumb model in the Component class instead via the
Component Template something is happening.
So instead of:
<t:heading t:id="heading"
t:breadCrumbs="${basePage.breadCrumbHolder.model}" />
I do in .java
@Component(inheritInformalParameters = true, parameters =
{ "loginPage=inherit:loginPage","breadCrumbs=basePage.breadCrumbHolder.model" })
