Re: Direclty using parent's compoundpropertymodel not possible ?
I think we're talking about two different things: I was talking about trying to access the model of a parent component, it sounds like you're talking about trying to access the model of a superclass. In the case I'm talking about, you can't access the inherited model in your constructor because your object hasn't been added to the parent component yet (it will be added after the constructor runs). Therefore you need to wait until onBeforeRender to do initialization that depends on inspecting the inherited model.

Re: Direclty using parent's compoundpropertymodel not possible ?
and that sub component must have the complete object?
or does the panel only have to have a property of that object?
If it has to have the complete object you can always make your own model
give the panel this kind of model:
public class SuperObjectModel implements IModel, IComponentAssignedModel
{
public Object getObject() {
return null;
}
public void setObject(Object object) { }
public void detach() { }
public IWrapModel wrapOnAssignment(final Component component)
{
return new IWrapModel()
{
public void detach(){ }
public void setObject(Object object){
}
public Object getObject() {
MarkupContainer parent = component.getParent();
while (parent != null !(parent.getModel() instanceof
IComponentInheritedModel))
{
return parent.getModelObject();
}
return null;
}
public IModel getWrappedModel() {
return SuperObjectModel.this;
}
};
}
}

Re: Direclty using parent's compoundpropertymodel not possible ?
oeps loop has to be something like this ofcourse
Component parent = component;
while ( (parent = parent.getParent()) != null
!(parent.getModel() instanceof IComponentInheritedModel))
{
return parent.getModelObject();
}
return null;

Re: Direclty using parent's compoundpropertymodel not possible ?
Thanks a lot for your answer. One question though : Johan Compagner wrote: CPM is used that child components can have sub objects/properties of that main object by using the child components id as the property how can I easily get the CPM in sub component ?

Direclty using parent's compoundpropertymodel not possible ?
Hi I have a compoundpropertymodel (cpm for the rest of the mail) set on my first level panel, then in one added second level panel I tried to do getModelObject(); which returned null. How comes ? I was expecting the cpm to be inherited in all my sub components... Is it possible to do so ? How should I do otherwise ? For the time being, I give a reference to the model at each sub component (panels, forms...) and directly access it, but I find it kind of not proper.

Re: Direclty using parent's compoundpropertymodel not possible ?
the second level panel does inherit it yet But it will not give you the object thats inside the first panel. CPM is used that child components can have sub objects/properties of that main object by using the child components id as the property if you want to inherited really the same component over all the childs you have to create your own InheritedModel johan On Wed, Jul 9, 2008 at 9:35 AM, ZedroS [EMAIL PROTECTED] wrote: Hi I have a compoundpropertymodel (cpm for the rest of the mail) set on my first level panel, then in one added second level panel I tried to do getModelObject(); which returned null.
