Hi,
I'm trying to use
http://wiki.apache.org/tapestry/Tapestry5HowtoSelectWithObjects to
create a selection for my Goal objects.
In the component I've got code
@Inject
private PropertyAccess _access;
public GenericSelectModel<Goal> getGoalModel()
{
_goalModel = new GenericSelectModel<Goal>(user.getGoals(),
Goal.class, "name", "id", _access);
return _goalModel;
}
And in the TML
<input t:type="Select" type="text" t:id="goalId" t:value="goal"
t:model="goalModel" t:encoder="goalModel"/>
But when I access the page I get:
Render queue error in BeforeRenderTemplate[Index:lygactionplan.goalid]:
Error reading property 'id' of
com.liftyourgame.application.entities.g...@40ff24: object is not an
instance of declaring class.
Any ideas on what I might be doing wrong? It would be so nice if
Tapestry handled selects of objects all by itself within the framework.
Thanks.
