According to the documentation of the event beforesubmit in Ext.form.Panel , I should be able to modify the values submitted, but I can't figure out how.
I've tried modifying the variable values, but this has no effect.Quote:
Implementations may adjust submitted form values or options prior to execution.
Any help is highly appreciated.
Note: I'm basically trying to send a JSON string, so I need to encode the values using JSON.stringify.
