[jboss-user] [JBoss Seam] - Re: Trinidad SelectManyShuttle with seam ?

[gjeudy]

Yes I figured later you can use both trinidad and richfaces.

I switched to rich:listShuttle component which did not require me any extra coding, I just kept using the same backing bean. The rich:listShuttle works as expected, I had to add the seam entity converter in converter attribute though, converter="#{org.jboss.seam.ui.entityConverter}"

Below is the backing bean code in case you still want to look at it.
