Problem updating bean from multi-select box
Hi,
I am having a problem with the internals of BeanUtils/RequestUtils when my
posting changes of a form to an action where the page contains a
multi-select box. Can anyone spot what I am doing wrong from the code
snippets below..?
[MyBean] (inside the Form Bean)
public void setMyFieldList(Collection myFieldList) (list
containing the options to choose from)
public Collection getMyFieldList()
public void setMyField (Collection myField) (the field in
question, multi-option)
public Collection getMyField()
[JSP]
<html:select property="myBean.myField" multiple="true" size="7">
<html:options name="myFormBean"
property="myBean.myFieldList"/>
</html:select>
The page renders fine and automatically selects the right items in the list
but when the page is updated things blow up trying to update the data back
into the bean inside RequestUtils.
Do I need to do anything else to tell the posted data to go back into the
main field (which is a collection)?
Thanks,
Andrew

Are you making sure that the MyBean instance exists when the form is
submitted?
