Problems with convertEntity in seam cvs

[dustismo]

Using seam from cvs today:

<h:selectManyListbox value="#{groupSelect.selected}">
 <s:selectItems value="#{groupSelect.items}"
 var="item"
 disabled="#{item.id == -1}"
 label="#{item.name}"
 />
 <s:convertEntity />
 </h:selectManyListbox>

results in stacktrace:

This is in a conversation, and it did work before I upgraded. Any help?

Where is groupSelect.selected coming from (code)

[dustismo]

I found the problem (finally).. I was adding dummy model objects (set id=-1) to signify disabled elements -- I need some kind of separator between different groupings. This worked fine in the last version but dies in the current version. How can I add disabled elements (headers) now?

Thanks much,
Dustin

You can't use convertEntity in this situation (it assumes that all objects in the list are entities, as would any converter). You can extend org.jboss.seam.ui.EntityConverter:

@Name("myConverter")
@Converter
public void MyConverter extends EntityConverter {

 public String getAsString(...) {
 if ("separator".equals(value) {
 // it's not an entity, you deal with it here
 } else {
 return super.getAsString(...);
 }
 }

 // similar for getAsObject
}

then you use it

<f:converter id="myConverter" />
