This is how I need to do it: I have a form with two submit buttons. One should add the content of a text field to a Vector (which is therefore in the form bean) without leaving the page, and the other submit button should point to another page that has access to the Vector values. So I have two action classes, one for each submit button. Pressing one of them should therefore add one value to the Vector. I try to do this in my JSP, because I don't know how to call a specific bean method from the action class... Hope I could explain it clearly...

In your load() action, you hit the db and generate some object for each row and put them into your vector. Your jsp loops over all of the objects in the vector and displays <input>s for each object (row) Sometimes, you may generate a row without a serverside call (javascript) then post the form. In this case the set(index, object) of your vector will cause an IndexOutOfBoundsException. For this case, I use a LazyList and a factory which creates an empty object at the new index, then struts can populate the object with the <input> values. http://jakarta.apache.org/commons/collections/apidocs-COLLECTIONS_3_0/org/apache/commons/collections/list/LazyList.html Balazs Michnay wrote: > Struts does not seem to accept a Vector-typed field as a property value.
