Hi folks,

We are trying to use DataPage in Pega so that use in Angular app.

My datapage works fine in Pega. However when I test in Angular app it doesn´t work. I get this error:

core.js:4117 ERROR TypeError: Cannot read property 'length' of undefined     at DropdownComponent.push../src/app/_fieldcomponents/dropdown/dropdown.component.ts.DropdownComponent.ngOnInit (dropdown.component.ts:108)     at callHook (core.js:2970)     at callHooks (core.js:2940)....

We identified that the issue is in this block of code in Angular app:

        let dpParams = this.fieldComp.control.modes[0].dataPageParams;         if (dpParams.length > 0) {

          pPage = new Object();

          for (let i in dpParams) {             let sVal : string;             if (dpParams[i].value != null) {               sVal = dpParams[i].value;             }             else {               sVal = dpParams[i].valueReference.lastSavedValue;             }

            pPage[dpParams[i].name] = sVal;           }         }  

If I comment this block the datapage works fine in Angular app. But I don´t think that it will be a correct solution. 

Pls, anyone have the same error? and How could you fix it?

Thks!
