Ting Rung,
You can do this in two ways:
- use a Struts form bean to collect all the values over the requests
- submit the changes of each request to bc4j, but do not post and commit the changes to the database.
The latter is easiest. For this to work, you must set the doCommit property of all your save actions in the stuts-condig to false, except for the last save action in the chain of requests.
In addition, in your application module class, you need to overwrite method postChanges as follows:
* DO NOT post the changes to the database
public void postChanges() throws Exception
// do not post here
// posting will happen when the commitChanges
// method on the handler is invoked
