DataProcessor

Handles client-server data saving operations.

Methods
attachEvent attaches the handler to an inner event of the component
attachProgress assigns handler for data saving actions
blockEvent temporarily blocks triggering of ALL events of the calling object
callEvent calls an inner event
clearValidation removes "data incorrect" highlighting from invalid text fields
define redefines a single configuration property (or a hash of properties)
detachEvent detaches a handler from an event (which was attached before by the attachEvent method)
escape escapes data
getItemState return update state for the item in question
getState gets the current DataProcessor state
hasEvent checks whether the component has the specified event handler
ignore ignores the data operation passed as the parameter (the operation will not be saved on the server)
mapEvent routes events from one object to another
off disables dataProcessor
on enables dataProcessor
processResult process data saving results
reset reset updated state for all items
save marks a data record as changed and initiates data saving
send sends a request to server
setItemState set update state for the item
unblockEvent cancels events blocking that was enabled by the 'blockEvent' command
