D365 - Get and Set lookup

Posted on by Community Member

Hi guys, I'm having some difficulty trying to get and set a lookup value. I've created a button on a Case form which opens up a new Email and I want to set the Regarding of that email to the case it just came from.

I don't know if there's a more clever way to do this - currently, this is what I have:

var formContext = executionContext.getFormContext(); //get formContext

function getLookupValue(executionContext) {
	var lookupObject = formContext.getAttribute(incidentid).getValue(); //get the Lookup Object
		if (lookupObject != null) { 
			var lookupObjectValues = lookupObject.getValue();//get the Lookup Value 
		if (lookupObjectValues != null) {
			var RecordId = lookupObjectValues[0].id; //get the Lookup id 
			var RecordName = lookupObjectValues[0].name; //get the Lookup Name 
			var EntitySchemaName = lookupObjectValues[0].entityType; //get the Lookup EntityName 
		}
	}
}
		
function setLookupValue(executionContext, regardingid, RecordId, RecordName, EntitySchemaName) {
	if(regardingid != null)	{
		var lookupValue = new Array();
			lookupValue[0] = new Object();
			lookupValue[0].id = RecordId;
			lookupValue[0].name = RecordName;
			lookupValue[0].entityType = EntitySchemaName;

		formContext.getAttribute(regardingid).setValue(lookupValue);//set lookupValue from array
	}
}

When the button is pressed and the event handler runs, I get a script error:

TypeError: Cannot read property 'getAttribute' of undefined

I feel like I must be missing something fundamental - I've gone through a few iterations with this (I was using the old Xrm.Page before - whoops!) but any advice would be very much appreciated!

RE: D365 - Get and Set lookup

Hi JVicente,

Make Sure in the Ribbon workbench, while doing COMMAND, Make sure you are passing CRM Parameter as "PRIMARYCONTROL"

then

Try changing the code like below

function getLookupValue(executionContext) {
var formContext = executionContext;

var lookupObject = formContext.getAttribute(incidentid).getValue(); //get the Lookup Object
if (lookupObject != null) {
var lookupObjectValues = lookupObject.getValue();//get the Lookup Value
if (lookupObjectValues != null) {
var RecordId = lookupObjectValues[0].id; //get the Lookup id
var RecordName = lookupObjectValues[0].name; //get the Lookup Name
var EntitySchemaName = lookupObjectValues[0].entityType; //get the Lookup EntityName

setLookupValue(formContext , regardingid, RecordId, RecordName, EntitySchemaName)
}
}
}

function setLookupValue(formContext , regardingid, RecordId, RecordName, EntitySchemaName) {
if(regardingid != null) {
var lookupValue = new Array();
lookupValue[0] = new Object();
lookupValue[0].id = RecordId;
lookupValue[0].name = RecordName;
lookupValue[0].entityType = EntitySchemaName;

formContext.getAttribute(regardingid).setValue(lookupValue);//set lookupValue from array
}
}

RE: D365 - Get and Set lookup

Hi,

According to the error message, the value of formContext is undefined.

You can try the following code(I created a on load event on email form and it can get the lookup value)

var formContext; function getLookupValue(executionContext) { formContext = executionContext.getFormContext(); //get formContext var lookupObject = formContext.getAttribute("incidentid"); //get the Lookup Object if (lookupObject != null) { var lookupObjectValues = lookupObject.getValue();//get the Lookup Value if (lookupObjectValues != null) { var RecordId = lookupObjectValues[0].id; //get the Lookup id var RecordName = lookupObjectValues[0].name; //get the Lookup Name var EntitySchemaName = lookupObjectValues[0].entityType; //get the Lookup EntityName } } } function setLookupValue(executionContext, regardingid, RecordId, RecordName, EntitySchemaName) { if(regardingid != null) { var lookupValue = new Array(); lookupValue[0] = new Object(); lookupValue[0].id = RecordId; lookupValue[0].name = RecordName; lookupValue[0].entityType = EntitySchemaName; formContext.getAttribute("regardingid").setValue(lookupValue);//set lookupValue from array } }
