Hi Josh
What was your encoding issue? I'm having the same issue here with a

You say you were able to get my code to work? As is, or did you need to

Re: [T5.1] AJAX Form Validation
Hi,
I wasn't the one with the problem, and I'm not sure that Levi ever
said what was specifically wrong.
Post the specifics of your problem in a separate thread and I'm sure
someone will be able to help.

Re: [T5.1] AJAX Form Validation
Hi Josh, Thanks for looking. I'm afraid the stack trace I provided is a red herring and does not have any bearing on the situation. It comes from the fact that my encoder was getting purged from the session due to it being set as FLASH only. And this exception actually only happens after I changed the code from: form t:id=parts t:zone=nothingSelectedZone to form t:id=parts t:zone=resultsZone which actually works... it's as if something in the form needs to be rebuilt after the submit. You say you were able to get my code to work? As is, or did you need to make changes? I'd still like to have the flexibility to refresh the nothingSelectedZone and not touch the resultsZone. Cheers, Levi Josh Canfield wrote: Your example code works fine and the exception you provide makes it look like you're in a loop? Caused by: java.lang.NullPointerException at org.apache.tapestry5.corelib.components.Loop.restoreStateFromStoredClientValue(Loop.java:457) That line from the code: // We assume that if an encoder is available when we rendered, that one will be available // when the form is submitted.
