Help Needed for Web Service

[gzhao888]

I have created a new display action to retrieve a record in a table through web services. What it does is that if a certain field in the record is empty, a javascript function defined in the process definition is called to populate the empty field through doHTTPRequest to another server. The code works, i.e., the javascript is getting called and the field is getting populated but the field value is NOT returned in web service response. It appears that the record is retrieved before my javascript is invoked. Anyone has a solution to fix this problem?

BTW, I have practically two-week experience with SC, so please explain to me as detailed as possible.

Thanks in advance.

I figured it this out. Just need to populate the field in $L.file from javascript return value in final javascript tab
