D365 V9{Upgrade}: “v_5 is not a function” error while adding custom filter to lookup

Recently, after upgrading our one of the D365 instance to V9, we came across an issue with custom filtering of lookup.

We were using below piece of code snippet to add custom filter:

if (formContext.getControl("sab_lnepackageid") != null) {

formContext.getControl("sab_lnepackageid").addPreSearch(addFilterOpp(executionContext));

}

and below is the definition of the addFilterOpp method:

function addFilterOpp(executionContext) {
var formContext = executionContext.getFormContext();

var brandId = null;
var brandLookup;
var enquiry;
var fetchQuery;
try {
//Check if control exist on form
if (formContext.getControl("sab_brandid") != null && formContext.getControl("sab_brandid").getAttribute().getValue() != null
&& formContext.getControl("sab_eventtype") != null && formContext.getControl("sab_eventtype").getAttribute().getValue() != null) {

brandLookup = formContext.getControl("sab_brandid").getAttribute().getValue();
brandId = brandLookup[0].id;

enquiry = formContext.getControl("sab_eventtype").getAttribute().getValue();

}
//Build fetch
if ((brandId != null || brandId != undefined) && (enquiry != null || enquiry != undefined)) {
 fetchQuery = ""

formContext.getControl("sab_lnepackageid").addCustomFilter(fetchQuery);
}
} catch (e) {
Xrm.Navigation.openAlertDialog("addFilter Error: " + (e.description || e.message));
}
}

fetchQuery = “<filter type=’and’>” +

“<condition attribute=’sab_brandid’ operator=’eq’ value='” + brandId + “‘ />” +
“<condition attribute=’sab_eventtype’ operator=’eq’ value='” + enquiry + “‘ />” +
“</filter>”;

However, the lookup was not working when we were clicking on magnifying glass of lookup. Checking the Developer Tools –> Console, we found the error message “v_5 is not a function and blah blah..”.

To fix this issue, we changed the code where we were passing execution context.

Below is the updated code snippet in which we removed execution context from the parameter and passed only the name of the method:

if (formContext.getControl("sab_lnepackageid") != null) {

formContext.getControl("sab_lnepackageid").addPreSearch(addFilterOpp);

}

and there was no change to the definition of the function addFilterOpp:

function addFilterOpp(executionContext) {
var formContext = executionContext.getFormContext();

var brandId = null;
var brandLookup;
var enquiry;
var fetchQuery;
try {
//Check if control exist on form
if (formContext.getControl("sab_brandid") != null && formContext.getControl("sab_brandid").getAttribute().getValue() != null
&& formContext.getControl("sab_eventtype") != null && formContext.getControl("sab_eventtype").getAttribute().getValue() != null) {

brandLookup = formContext.getControl("sab_brandid").getAttribute().getValue();
brandId = brandLookup[0].id;

enquiry = formContext.getControl("sab_eventtype").getAttribute().getValue();

}
//Build fetch
if ((brandId != null || brandId != undefined) && (enquiry != null || enquiry != undefined)) {
 fetchQuery =""

formContext.getControl("sab_lnepackageid").addCustomFilter(fetchQuery);
}
} catch (e) {
Xrm.Navigation.openAlertDialog("addFilter Error: " + (e.description || e.message));
}
}

fetchQuery = “<filter type=’and’>” +

“<condition attribute=’sab_brandid’ operator=’eq’ value='” + brandId + “‘ />” +
“<condition attribute=’sab_eventtype’ operator=’eq’ value='” + enquiry + “‘ />” +
“</filter>”;

After making the above change the custom filter started working on lookup.

NOTE: This change is working on only Chrome and IE browsers. On Firefox, it’s still not working.

Hope it helps !!
