orderingList bug? PropertyNotFoundException on form submissi

[mhassel]

I have an ordering list within my a form as shown below - straight forward enough!

The backing bean has of course a getter for the audit categories.

All works nicely except when I submit the form I get the following error:

Is this a bug in my code or in richfaces...

Oh, I forgot: The return type of the backing bean getter is an array of category object, there is no way I could accidentally end up with a "string" in there

[mhassel]

Update:

I changed the columns to print the classname and the value of the row variable...

Before form submission, everything is correct. AFTER form submission and subsequent rerendering, the row variable points to a "string", the content is the classname and index of the class in the collection it is supposed to be, like: ca.ba.....category@1

[mhassel]

Update:

Digging through the renderer, it appears that th default renderer just returns the string that gets passed in instead of correctly converting into the data object specified by the value binding.

When can we expect this to be fixed? Certainly it can't be the proposed solution that whenever someone has to use the list control she has to write her own custom converter....

Is there any new information about this subject by now?

guys List Shuttle and Ordering List components requires converter for your Objects and hasCode and equals methods properly implemented. Check List shuttle livedemo code. There is submit occurs properly.
