Why when I switch to v2.0 cant get a form in the front end working?

- Validation Rule missing: positive_integer

when I download and install it locally (joomla 2.5., cant add a menu direct to the add form (front end layout)

and when test it on sand box works ok, except for the menu that is messed up (the menu)

- Also I deleted some projects and still showing in sandobox, after, rebuild it flush data etc.

This is becuse the '_' (underscore is not anymore handled).

Now this is fixed.
Change regex and select it back, the default alias is not correct.
