[Vtigercrm-developers] extend Validation engine (Ajax)

[Uma S]

Hi Alan,

*I've looked at the checkDuplicateName function in Vtiger_Helper_Js() and
am trying to work out how this is used by Account's Detail.js but I'm a bit
(very) confused. I don't really understand this jQuery.Deferred() stuff.*

Api which is making call to deferred api in jQuery, should wait until the
deferred api returns back the response from executing the following lines
after deferred call.

For example : In Accounts Detail.js saveFieldValues() api is making call
to isAccountNameDuplicate() api which is an deferred api. So the line
following the call to isAccountNameDuplicate() api will not execute until
response is returned from the called  api.

Hope, my explanation might add some value.
