CompoundPropertyModel binding direction
I'm trying to use CompoundPropertyModel in a form I dynamically create with a
RepeatingView. I use the CompoundPropertyModel#bind method to bind each input
tag to the corresponding java bean property.
Binding from java bean to html does work (the fields get filled), while the
other way around (onSubmit) does break... the reported error is "no get method
defined ... singlePanelForCurrentRow", where singlePanelForCurrentRow is the
wicket:id I use to attach the repeating input tags.
I don't know what to search for on Google, because searching obvious terms
(CompoundPropertyModel binding and the like) yelds trivial examples, but
nothing similar to my needs.
Here is a quickstart demonstrating the issue, try clicking submit:

Thanks in advance
Lucio.

Sure, that's perfectly fine.

Well, to be honest I don't understand the full meaning of the sentence (why my
design conflicts with Wicket serialization), but let's leave that to Google,
I'll have a look.
However I'm curious to know if a possible solution would be to create the
DetailPage instance inside the onClick method of the Link, so that it becomes
a local variable that gets collected asap.

Hi Lucio,
your LabelAndField and DetailFormComponentPanel both extend
FormComponentPanel. Thus they will take part in form processing and try
to push a value into their model.
Since there are no properties "singlePanelForCurrentRow" and
"detailEditorPanel" the model update will fail.
FormComponentPanels are an advanced concept and I'd recommend you extend
org.apache.wicket.markup.html.panel.Panel until you really need the
features of a FormComponentPanel.
BTW your HomePage shouldn't keep a reference to another page (i.e.
DetailPage), since Wicket serialized pages separately.
Hope this helps
