States and Eval in Views

[Jürgen Stiefel]

Hi everbody,

trying to switch a label on and off with the following statement within a module view definition.

            <label name="surface_properties" states="{'invisible': Eval('active', True)}"/>

But all I receive is an error message "Invalid XML for View ...".
Can anyone help to fix this problem.

Thanks and regards
Jürgen

You can not more put Python code in XML, it must be PYSONinfied.
The easiest way to do that is by using ModelView.view_attributes
