Breaking: #82093 - EXT:form Partials/Field/Field.html has changed 

Description 

To let the form field viewhelper attribute errorClass work, the partial EXT:form/Resources/Private/Frontend/Partials/Field/Field.html has been changed.

<f:form.validationResults for="{element.identifier}">

has been changed to

<f:form.validationResults for="{element.rootForm.identifier}.{element.identifier}">

Impact 

Users who overwrite this partial by its own partial have to make adjustments. Otherwise no has-error class will be rendered in case of form validation errors into the parents <div class="form-group"> and the <span class="help-block"> content will not be rendered.

Affected Installations 

All installations with overwritten partial EXT:form/Resources/Private/Frontend/Partials/Field/Field.html

Migration 

Change the partial Field/Field.html within your site package.

<f:form.validationResults for="{element.identifier}">

change to

<f:form.validationResults for="{element.rootForm.identifier}.{element.identifier}">
