No Collection found exception comes when the collection returned from
the property on the bean is null.
My guess would be in your Action, you might not be setting the
collection properly to the form.
I see this statement in your Action,
ListadoFormatosForm listadoFormatosForm = null;
How are you initializing your listadoFormatosForm, are you creating a
new ListadoFormatosForm?
If you create a new ActionForm bean, you have to set it to the request
under the name declared in the action mapping.
You can also cast the ActionForm form, that comes to the execute
method to your form, as in,
ListadoFormatosForm listadoFormatosForm = (ListadoFormatosForm) form;
then you don't have to set it to the request.
Thanks,
Kishore Senji.
