Ron_sf009 Calling Continuation Object (framework) from Trigger
I was planning to make a Continuation object callout form Trigger. I have a requirement to invoke asynch Webservice callout whenever records is created or updated. . Hence just wanted to know if it would be possible to make use of continuation object callout from Trigger.
>> Beacuse continuation is a asyncronous callout and the response back with a callback method and After execution of callback method only data is presented back (presented back where ?????? to the viosualforce page).
>> Where as trigger is fire an forget principle. it neither can hold back response of call back method or prsented back. it will excute and move on.
>> so the continuation object method need to be called from a visualforce (JS remoting/actionfunction/method) and once exceution of callback done data will be sent back to page and display whereever u want in page.
