Hi, everybody!

I work on Classic UI. I have a task: to realize opening mini-page instead of full page in Account Lookup by clicking Add Button. 

I managed to do it in runtime mode.

To do this, it was necessary to make a change to the basic client module  LookupPageViewModelGenerator.js, the needOpenMiniPage method.

But I couldn't override this basic module in the configuration and connect it to my page.

Code of my new LookupPageViewModelGenerator:

define("LVLookupPageViewModelGeneratorV2", ["LookupPageViewModelGenerator"], function(LookupPageViewModelGenerator) {
 
Ext.define("Terrasoft.configuration.LVLookupPageViewModelGeneratorV2", {
extend: "Terrasoft.LookupPageViewModelGenerator",
		needOpenMiniPage: function(entitySchemaName) {
		this.lookupInfo.isQuickAdd=true; // додано
		const notUseSilentCreation = !Terrasoft.Features.getIsEnabled("UseSilentCreation");
		const entityStructure = moduleUtils.getEntityStructureByName(entitySchemaName);
		const editPages = entityStructure.pages;
		const hasAddMiniPage = editPages[0].hasAddMiniPage;
		return notUseSilentCreation && this.lookupInfo.isQuickAdd && !Ext.isEmpty(hasAddMiniPage);
				},
    		});
    return Terrasoft.configuration.LVLookupPageViewModelGeneratorV2;
});

Code of my page where lookup is contained:

define("ELFinApplicationAccountPage", ["LVLookupPageViewModelGeneratorV2"],  function() {
return  {
entitySchemaName: "FinApplication",
attributes: {},
messages: {},
details: /**SCHEMA_DETAILS*/{}/**SCHEMA_DETAILS*/,
businessRules: /**SCHEMA_BUSINESS_RULES*/ {}/**SCHEMA_BUSINESS_RULES*/,
methods: {},
diff: /**SCHEMA_DIFF*/[
			{
          operation: "insert",
          name: "LVPartnerWhoRecommended",
          parentName: "AdditionalProfileInfoContainer",
          propertyName: "items",
          values: {
            layout: {
              column: 0,
              row: 6,
              colSpan: 24
            }
          }
        },
         ]/**SCHEMA_DIFF*/
         };
});

I wrote this code while I was reading this article: https://community.creatio.com/questions/add-mini-card-contact-lookup-new-optionbutton. But maybe I made a mistake or didn`t take smth into account.

What do I have to do to make this work?

Thank you!
