invalidMessage vs invalidMessageList in xCP

ilya basin

Hi. We use xCP 16.4P6 and we have remnant expressions in our project that look like this:

widgets.<widgetId>.invalidMessage

The validator does not complain and the expression has the type string, single.

However, it's not in the list of suggestions, but another one is:

• Invalidity message (invalidMessageList)

I didn't work with xCP 2x. Does "invalidMessage" originate from there?

I also noticed that at least for text inputs the expression actually returns

{ widgetId: "<widgetId>" } 

instead of a string and this causes errors.
