Odd exception from Alerts and JSONObject

2014-08-05 Thread Richard Frovarp 
I am see this exception in my logs. It appears to be from when a user 
clicks dismiss on an alert. It doesn't hurt anything, but it certainly 
pollutes the logs. We are running 5.3.7 and the latest Tapestry5-JQuery 
library. Not entirely sure where this is happening. ViewEvent:layout 
probably refers to our custom layout module. Line 45 of Layout.tml is 
t:alerts /. It looks like new JSONObject is being returned, which 
might serialize to {}. No idea why it's having trouble with that.

Re: Odd exception from Alerts and JSONObject

As far as I can remember, this was a known issue already fixed for 5.4.
