with this code, you're trying to set a PersonnelrecordsDepartment Object
into the field called parentId of the object referred to by the
'selected' variable
that you're passing to the CompoundPropertyModel. The data types don't
match, that's why wicket trys to safe the day using conversion (which obviously
cannot succeed in this case...).
You can either:
a) change the data type of the parentId field of your 'selected' object
or
b) change your dropdown choice so only the id is propagated instead of the
whole PersonnelrecordsDepartment Object. you could do that e.g. by
setting the ids
as choices, and use a custom choicerenderer which retrieves and
renders the PersonnelrecordsDepartment Objects
I hope that helps...
