I've a field at Lead table named Product (crf2e_service) , And at product table there are 3 bool fields named Individual, Private, Governorate,

Contact is individual, and Account contain a classification field (Private, or Governorate)

At Creating lead i want when user choose Existing contact filter product according to individual type only, and when user choose account filter according to classification

The JS code i write works only at the first time i choose contact or account, when i remove or choose another type not clearing filter or change it

I but onload method at Form OnLoad Event Handler And applyProductFilter at Existing Contact, And Existing Account OnChange Event Handler

var isProductFilterApplied = false;

function onLoad(executionContext) {
    var formContext = executionContext.getFormContext();
    var formType = formContext.ui.getFormType();

    if (formType !== 1) return; // Only apply for new records

    console.log("onLoad executed, form type: " + formType);

    // Add OnChange event handlers for parentcontactid and parentaccountid
    var parentContactField = formContext.getAttribute("parentcontactid");
    var parentAccountField = formContext.getAttribute("parentaccountid");

    if (parentContactField) {
        parentContactField.addOnChange(function (context) {
            applyProductFilter(context);
        });
    }

    if (parentAccountField) {
        parentAccountField.addOnChange(function (context) {
            applyProductFilter(context);
        });
    }

    // Apply filter on load
    applyProductFilter(executionContext);
}

function applyProductFilter(executionContext) {
    var formContext = executionContext.getFormContext();
    debugger;
    var parentContactField = formContext.getAttribute("parentcontactid");
    var parentAccountField = formContext.getAttribute("parentaccountid");

    var parentContact = parentContactField ? parentContactField.getValue() : null;
    var parentAccount = parentAccountField ? parentAccountField.getValue() : null;

    console.log("applyProductFilter executed");

    clearProductFilter(formContext);

    if (parentAccount) {
        var accountId = parentAccount[0].id.replace('{', '').replace('}', '');
        console.log("Parent Account ID: " + accountId);
        filterProductsByAccount(formContext, accountId);
    } else if (parentContact) {
        var contactId = parentContact[0].id.replace('{', '').replace('}', '');
        console.log("Parent Contact ID: " + contactId);
        filterProductsByContact(formContext, contactId);
    } else {
        console.log("No parent contact or account selected");
    }
}

function clearProductFilter(formContext) {
    var productField = formContext.getControl("crf2e_service");

    if (productField) {
        console.log("Clearing product filter");
        productField.removePreSearch(productFilterHandler);
        productField.addPreSearch(function () {
            productField.addCustomFilter("<filter type='and'></filter>");
        });
        isProductFilterApplied = false;
    }
}

function productFilterHandler() {
    // Dummy function to use as a reference for adding/removing the handler
}

        },

                filter = "<filter type='and'><condition attribute='crf2e_isprivate' operator='eq' value='true' /></filter>";
            } else if (classification === 1) { // Assuming 1 is the value for Government
                filter = "<filter type='and'><condition attribute='crf2e_isgovernment' operator='eq' value='true' /></filter>";
            }

            applyProductLookupFilter(formContext, filter);

Hi,

I checked your code and analyzed it according to your problem.

I learned a bit about the functions removePreSearch and addPreSearch, but addPreSearch can't directly override the previous filter, it needs to be removed by removePreSearch first.
Because you're adding an anonymous function to addPreSearch, you can't remove it with the removePreSearch method.
The removePreSearch method takes one argument, a reference to the event handler you want to remove.

So you need to use a named function instead of an anonymous function. For example, you can define a function first and then use the name of that function in addPreSearch and removePreSearch.
You can try to change it as I suggested above.
