One solution is to make the increment of the array size a separate request so that your Bean can be expanded, i.e. insert rows, add record.

Hi all, I have a fairly involved problem surrounding token checking for request reload management. There are various methods available in the Action class such as saveToken, resetToken and isTokenValid which are all very useful in helping manage reload requests. All these methods operate off a token stored in the session, which these methods access directly from the request object. There is no dependence on the form object for these methods. A problem arises when, during the normal processing of a request, the form object is modified in such a way that array elements in the form are removed. For example, an array of transactions in the initial request has 10 elements in it, during action processing this array is resized due to some business rule down to 5 transactions. The array has only 5 elements in it now. The next screen is displayed. If a reload request is sent now, the number of transactions in the request is still 10 but the form object only has a transaction array with 5 elements in it. When the request processor attempts to populate the form object with the request data an ArrayIndexOutOfBoundsException occurs which is understandable but very undesirable. Should the token functions be moved into the org.apache.struts.util .RequestUtil class so that they are available to the RequestProcessor? We can then check for reloads prior to the form object being populated in the processPreprocess method in the RequestProcessor. Very interested in anyone's thoughts on this. It looks like we will have to set something up ourselves to do this but if Struts itself could change to accommodate this it would be very useful.
