options tag
hi guys
I have the following case.
My ActionForm has a ArrayList called artistCollection which gets
populated with Artist objects in the Action class.
I now have to generate a select box using this ArrayCollection.
The jsp page has the following code to populate the drop down box.
<html:select property="artistId1">
<html:options property="artistCollection"/>
</html:select>
However this is generating a ClassCastException error. Can any one tell me whats going on
here.. I need to generate the dropdown box with artist id as the value
of the options.
I am also enclosing some portions of my code
Thanks for your assistance
Anand
