Mike,
Are you still having a problem with this? If so...looking at your original JSP tags, I am sure that the problem is with your names not matching up. This is what needs to happen:
<logic:iterate id="alert" name="alertListForm" property="userAlerts"> <bean:write name="alert" property="startingLocation.locationId" /> </logic:iterate>
In the object called "alertListForm", there must be a getter and setter for "userAlerts": getUserAlerts() and setUserAlerts(Collection userAlerts). Those methods will return and accept a collection of objects that in this case are LocationDTO's.
When you iterate, each object in the iteration will be known as an "alert", so the property that you specify has to have a getter/setter. In this case, your property should be "locationId". Once again, insure that you have the matching getter/setter methods: getLocationId() & setLocationId(String locationId).
You do need to be careful with the capitalization. We have found that sticking to the java naming standard works best. Defining a property that begins with an uppercase throws Struts for a loop.
Hope this helps, Nick
