[SOLVED] Umbraco 7 regex error: Value is invalid, it does not match the correct pattern

I am seeing this error:

Value is invalid, it does not match the correct pattern

When I set a regex pattern in the doctype "Generic Properties" on something that is optional.

For example I setup a new UmbracoCMS 7.2.1 using Nuget with Visual Studio 2013 and after all the auto configuration/setup I went to the settings and added a regex to a new "optional" property called "title". Now when I go into "Content" and try to publish a page with the "TextPage" doctype (leaving the "Title" field blank) it returns the above error after postback for the "Title" field, even though the "Mandatory" checkbox is unchecked. Is there a work around for this ?

I first encountered this error in an existing Umbraco site that I just upgraded from v4 to v7.2 and I thought something had corrupted the templates but it doesn't seem to be the case.

Any help will be appreciated.

By providing a regular expression for the field you in turn make it mandatory. If you wish for the field to be optional then you must either omit your regular expression or alter it so that it also accepts an empty value.

I do not mind them remaining dormant in the database but do not want the client (who will be logging on as an Admin) see them ...

Umbraco: Document Type Chain by Composition

Can I use Composition in Umbraco 7.5 to make a property inheritance chain, like BaseType > ContentPage > HomePage, in which ContentPage has its own properties and inherit all properties from BaseType, and HomePage has its own properties and inherit all properties form ContentPage explicitly, and of course from BaseType implicitly? For some reason, I can make ContentPage to have a composition of type BaseType, but then for HomePage, Umbraco doesn't display ContentPage as an option. I thought the new Composition feature has replaced document type hierarchies (defining documen...
