Updating ActionForm from indexed properties

["Mulligan, Scott H" <sc...@eds.com>]

  

My actionForm has an ArrayList of objects that I display in my JSP for update using indexed properties (see below JSP code):

		<logic:iterate id="objectVO" name="FormConfig" property="objectCollection" type="com.xxx.MyType">

		<html:text name="objectVO" property="stringProperty" indexed="true" />

		<html:text name="objectVO" property="intProperty" indexed="true" />

		</logic:iterate>

My Action Form looks like this:

		public ArrayList getObjectCollection() {return objectCollection;}

		public void setObjectCollection(ArrayList p_ObjectCollection) {objectCollection= p_ObjectCollection;}

		public void setObjectVO(int index, MyType  p_object) {objectCollection.set(index, p_object);}

		public MyType getObjectVO(int i) {return (MyType) objectCollection.get(i);}

The object class has a String property and an int property.

The information gets displayed properly and updated properly when valid data is entered. However, if the user enters a non-numeric value for the intProperty field, the int property in the object in the ArrayList in my actionForm gets set to 0. Is there a way to trap this situation or to a way to avoid this from happening?

Thanks for your help
