[Woody] Select List inside Repeater Widget

[Jim Horner <jh...@arinbe.com>]

Hi,

Has anyone tried or is it possible to use a selection list inside a repeater 
widget that changes a second selection list inside the same repeater widget? 
I don't know how to better describe it. An example, I have a page which 
allows the user to fill in Part data, name, number, etc. At the bottom of the 
page I would like the user to be able to input alternate parts. The alternate 
parts is the repeater. Inside the alternate parts is two selection lists. One 
is a part name and the other is a part number. When the user changes the part 
name, the part number selection list will fill in. This is similar to the car 
selector example; make/model except in a repeater.

The problem is when <wi:styling submit-on-change="true" /> fires, the 
flowscript errors out with 

java.lang.IllegalArgumentException: Invalid submit id (no such widget): 
alternateParts.0.alt.partName

If this is not possible that is fine. I think I am getting a little carried 
away with all of the power of flowscript and woody. I'll have to display the 
input a bit different is all.

Below is a snippet of my definition. I also just realized the javascript is 
wrong because I don't know the name of the widget, for example, 
alternateParts.0.alt.partName; I won't know the 0 or 1 or 2, etc to fill in 
the part numbers row selection list. I'm thinking what I am trying to do is 
not possible.

Thanks,

Jim
