> I'm experiencing a problem with tapestry's palette component. I'm using it with the reorder parameter set to true. Reordering the
> selected values works fine and the values are sent to the server in the expected order. However, if the page reloads and I submit the
> containing form again without changing the palette's values, the original order is restored and sent to the server resetting the
> previously arranged order.
> AFAICT, this relates to the hidden form field used by the palette and the updateHidden Javascript method. This method is called whenever the
> order of the selected options is changed. It is not called however when the Palette object is instantiated, so the hidden field keeps the
> sorting that comes from the server. 
> I believe, this could be fixed by calling the updateHidden method at the end of the Tapestry.Palette.initialize method. The following patch
> does this:
