This article shows how items passed through a trigger can be queried from the script.
Lets assume we have already added a Site-Defined Trigger to call zMyScript and pass the Assignee value.
Example:<source lang="javascript">POST_VALIDATE zMyScript(assignee) 111 FILTER(EVENT("UPDATE"));</source>Lets focus only on the zMyScript(assignee) portion.
Three items of information regarding the assignee are passed from the trigger to the script.
[1] is the original state value before editing began.
[2] is the last known value when the trigger was initiated.
[3] is the new value that is expected to be saved.
We can then query item [1], [2], or [3] in our script as needed.
Example:
<source lang="javascript">cr::zMyScript(...){
if( is_null( argv[3]){
set_error( 1);
set_return_data( "Assignee need to be filled.");
};
};</source>
