Web Form - Required Child Elements in Optional Parent

[buck_99]

Hi.

I have a parent element that is not required.  Iff the parent element is present, then one of its children is required.  Alfresco won't allow me to get past to step 3 of the Create Web Content wizard because I am leaving the required child field empty, although it is my intention to leave the whole parent empty. 

Thoughts?

I'm having similar issues, (excuse the mess) this does allow me to add an image and the copyright be validated or remove the image and the copyright is no longer mandatory.

On a more general note - I'm having trouble predicting how my XForms schema will behave and can't find any meaningful documentation that lets me have the control I need over the output. Given Alfresco WCM relies heavily on Javascript driven widgets, is it necessary to use XForms to create content? Can I build my own input screens easily? Some of the XForms functionality is great straight out-of-the-box but some much-needed functionality seems to be impossible to implement, i.e. Conditional fields and validation.

I'm experiencing the same error.

When setting minOccurs="0" maxOccurs="1", I would expect the web form to render a contracted, empty element - the same as it would by default when displaying a form for an element with minOccurs="0" maxOccurs="<anything greater than 1>".  Entering content for the one optional instance would be performed by clicking the + button.
