When selecting two items from selectManyListbox I get the following validation
error:
anonymous wrote : Conversion Error setting value '7 9' for '#
{workgroupSelectedStudents}'.
Evidently person with Id 7 and 9 were selected, but what is causing this
validation error? I tried overriding equals() and to match objects on their @(protected)
field. This yielded the same result. Can anyone shed some light on this? I am
deploying this on Jboss 4.2.0.GA and Seam 2.0.0.GA.
