Hello,
I would like to provide a Vaadin-based form to edit a very extensive (50+ (nested) attributes) JPA entity (there will be lots of text input fields and combo boxes). Because of the numerous fields the form should display the fields divided into several tabs.
What is in this case the best way to bind the entity data to the input fields and to provide all the values for the combo boxes? Is the Bean(Item)Container advisable or should I use JPAContainer?
Does anyone have experience with a Vaadin form which is partitioned into tabs? What might be pitfalls (e.g. I can think of validation warnings happening on a tab which is not active)?
Thanks for your help.
Florian
