Howard M. Lewis Ship commented on TAP5-299:
-------------------------------------------

I'm reminded of the joke: "Doctor, it hurts when I reach like this."  "Well, then don't do that!"

If you are going to swap out the set of options on the client side, you better be prepared for the submission on the cient side with a matching SelectModel.

> Create a model with A,B as the available options and set the palette value parameter to a list with C. You will get a NPE here:
> org.apache.tapestry5.internal.util.SelectModelRenderer.option(SelectModelRenderer.java:49)
> org.apache.tapestry5.corelib.components.Palette$SelectedRenderer.render(Palette.java:147)
> because valueToOptionModel in Palette doesn't contain a mapping for C.
