Hi,
I posted this a week ago and didn't get a resolution - now I'm back on the
case I would appreciate a few ideas on what else I could try:-
Here's a bit more info (bean names etc sanitised to protect the innocent...)
The main FormBean:-
public class MyFormBean extends MyAncestorFormBean {
private MyBean myBean = null;
<snip getters/setters and other stuff>
}
The embedded bean:-
public class MyBean extends SomeOtherBean {
private Collection myCollection = null;
private Collection myCollectionListData = null;
<snip getters/setters and other stuff>
}
Relevant content of the JSP with the multi-select box:-
<html:select property="myBean.myCollection" multiple="true"
size="7">
<html:options name="myFormBean"
property="myBean.myCollectionListData"/>
</html:select>
Error log:-

Basically, I have a field on a page which is a multi-select box showing 7
items. The currently selected values are in "myCollection", the available
values are in "myCollectionListData". The HTML <SELECT> displays fine with
all the options but when I submit the page, and Struts (more specifically
Jakarta Commons), tries to put the data back into the form bean, it blows up
with the error above.
Am I missing something or will the above just never work? If I'm barking up
the wrong tree can anyone suggest an alternative approach?
Thanks,
Andrew
