Hello @osantos1910, Thank you for providing the form embed URL. We are not seeing this issue on our side using Formio.js versions 4.9.20 as well as version 4.10.0-rc.3. Could you provide a JSFiddle of this issue so we can replicate on our side?

Hello @wag110894 . Thanks for your answer. I'm still getting the issue. As explain above I use angular-material-formio not only Formio.js. When I use angular-formio all works fine and I getting the expected behavior, but all stop working when instead use formio I use mat-formio tag.

This is my app.component.html <mat-formio src="https://pbojhsynrxckvwh.form.io/test-resource" (submit)="onSubmit($event)">

This are the dependencies of my package.json { "@angular/animations": "^8.2.14", "@angular/cdk": "^8.2.3", "@angular/common": "^8.2.14", "@angular/compiler": "^8.2.14", "@angular/core": "^8.2.14", "@angular/elements": "^8.2.14", "@angular/flex-layout": "^8.0.0-beta.27", "@angular/forms": "^8.2.14", "@angular/material": "^8.2.3", "@angular/platform-browser": "^8.2.14", "@angular/platform-browser-dynamic": "^8.2.14", "@angular/router": "^8.2.14", "angular-material-formio": "^1.26.0", "formiojs": "^4.10.0-rc.4", "hammerjs": "^2.0.8", "rxjs": "^6.5.5", "tslib": "^1.11.2", "zone.js": "^0.10.3" }

I think the issue is related to method setPage of Formio.js. Here this.redraw() is treated as a Promise and instead in angular-material-formio library redraw() method not have return statement returning undefined and not a promise.

this.redraw().then(function () { if (!_this11.options.readOnly) { _this11.checkValidity(_this11.submission.data, false, _this11.submission.data, true); } });

I review method nextPage() on formio.wizard.ts of angular-material-formio library, this method call nextPage of the instance in this case Wizard from Formio.js and that trigger redraw method of the instance.

nextPage() { this.instance.nextPage().then(() => this.stepper.next()); }

Adding a catch to this method I get the following error: TypeError: Cannot read property 'then' of undefined
