Hello, I've got an error which I can't reproduce in the showcase.

It happens with a DynamicForm where some formItems have a *When rule.
It only happens if the form and the Window which contains the form have not an explicit ID.

This is the js stacktrace:

This was working before (as I've got many forms in modal windows and without IDs)

At line 117186 there's this line:

isc.AutoTest._locatorDetails.firstParentOfIndex = canvas.parentElement.ID;

and canvas is a modal Window, so it hasn't a parentElement

A fix has been committed to address this issue. It was triggered by an autoPersistViewState grid pulling a special locator before the *When rules were created leaving behind a condition causing the bad reference. Available in builds starting with 10/3/2019.
