UI Action on form to only show wen related list is empty

[Sam Ogden]

Hi all,

I've got a custom UI action on the sc_task table.  I want to include a condition to only make this action display when there is no record matching in a related m2m list.

I've created this function in a script include called 'CdlStandardChange' :

linkedToChng : function(sctask){
		var link = new GlideRecord('u_m2m_catalog_task_change_reque');
		link.addQuery('u_catalog_task', sctask);
		link.query();
		if(link.next()){
			return true;
		} else {
			return false;
		}
	},

I have my condition in the UI Action as:

current.request_item.cat_item == '38190489dbd13240ddb9338ffe9619ed' && !CDLStandardChange().linkedToChng(current.sys_id)

The UI Action is called 'Add to Standard Change' and I only want it to display when there is not change linked to the sctask in the 'u_m2m_catalog_task_change_reque' related list.

The UI action adds a record to this related list, so esentially once the button has been clicked once I want it to no longer display to prevent duplicate entries into the m2m table.

I will then want a different UI Action to appear when a record does exist in the m2m and not display when there is not a record (the opposite logic)

Thanks

Sam
