Hi,
Hi!
I am trying to get a palette working with simple pojos to be displayed
in the "available" list. I am working with Tapestry 5.0.11.
That's a very old version . . .
I get the following NullPointerException:
Caused by: java.lang.NullPointerException
at
org.apache.tapestry.internal.util.SelectModelRenderer.option(SelectModelRenderer.java:49)
I've seen this error before when there's some value in the selected list
that isn't available in the model. Also make sure the Crop class has a
good equals() method.
