My form has a multivaluewidget, it's values are retrieved from an Arraylist in the bean that is populated using Hibernate. The user then selects a few values and presses "next".
Now i would like to save these selected values into a different arraylist then the one where the values are retrieved from. Rationale: i don't want to destroy the original dataset because it's quite expensive to retrieve.
Is changing the setter method for the Arraylist the only option here? Or can i somehow in my javascript binding say "save the collection into a different location in the bean" ?
I would use two bindings, one for load, one for save. So you have also two contexts:
<fb:value id="widget" path="context1" direction="load"/> <fb:value id="widget" path="context2" direction="save"/>
I use this (with repeater bindings) when loading entries from a uploaded CSV file (transformed via Chaperon to DOM) and saving to a bean. Thw advantage is that the CForms binding framework does the handling of the contexts for you, you don't need to navigate in javascript binding using JXPath or in your Java code with non-standard setters.
