Hi,
I would like to display and update a checkboxlist (or any multi-
select tag) using a List in Struts 2, but can't find complete
documentation or an example on how I should go about it. From
reading bits and pieces of the fragmented docs and sparse wiki, I
have the following so far:
My action contains (with getters and setters):
private Recipient recipient;
private List allProfiles;
@Element( value = com.blah.contactn.model.Profile.class )
@Key( value = java.lang.Long.class )
@KeyProperty( value = "id" )
private List<Profile> selectedProfiles = new ArrayList();
The model has a Recipient which contains a List<Profile> in a many-to-
many mapping. Profile only has two fields: Long id and String name.
The jsp is:
<s:checkboxlist list="allProfiles" listKey="id" listValue="name"
label="Profiles" name="selectedProfiles" value="recipient.profiles"/>
This displays the checkboxes correctly, but when I try and submit the
form, I get a:
IllegalArgumentException occurred calling getter of
com.corsaire.contactn.model.Profile.id; nested exception is
org.hibernate.PropertyAccessException: IllegalArgumentException
occurred calling getter of com.corsaire.contactn.model.Profile.id
The save() method is performing:
recipient.setProfiles(selectedProfiles);
recipientManager.save(recipient);
I've spent a frustrating 3 days trying to find a single full example
of using any multi-select tag in Struts 2 that isn't completely
trivial. Surely this is one of the most common UI elements used in a
web app? I know this is not strictly an appfuse problem - but
perhaps users have come across a useful example.
regards,
Stephen
