I’ve read through a couple of posts on the same topic. The problem is always the same: there are no visible values in the right hand column of a
TwinColSelect
although
getValue()
does indeed return a
Set
with some members of the type expected.
In my case the TwinColSelect is bound to a bean which ultimately comes from JPA.
My class is called
UserGroup
and it implements
toString(), equals() and hash()
.
Both the left-hand side and the right-hand side contain an underlying value which in both cases is
Set
, as expected. The left-hand side is able to display visible values just fine, supposedly using the
toString()
method on
UserGroup
.
Couple of questions:
- Disregarding the problem with the display of values in the right-hand side why is the left-hand side able to display those exact same object types just fine? (I would expect some symmetry: either none of the sides work or both of them work).
- The real question: What am I missing that makes the values in the right-hand side invisible?
Thanks.
