current record value client script not on the g_form

mrswann · ‎09-02-2016

from the sc_task table, I have the following:

function onLoad(){
   var reqitem = g_form.getReference('request_item');
   //alert(reqitem.cat_item);
   if (reqitem.cat_item == ('hardcodedsysidpleasedontshootme') || reqitem.cat_item == ('ipromisetomovethistoasysproperty'))
   {

so I know from the Task, I can get the request_item as it is on the form and from that reference I can get the cat_item

But up a level, if I want to get the cat_item from the sc_req_item itself !! It is not present on the form so how I can access it?

Should I just add the item to the form?

I have found that if a field is not available on the form it is not found using g_form methods. You could make the field available on the form, then create a UI Policy that hides it since it probably is not needed on the sc_req_item form. Then your g_form methods will work.

Let us know if you are still unsuccessful,

Another solution to placing the field on the form and then hiding it with a UI action is to use g_scratchpad to pass the value from the server side to the client side. Then you know it's always available even if someone re-arranges the form layout later.

The thing I like about this is it is Best Practice and is somewhat future proof - thank you
