I'd like to write a TALES expression. It will be used as a condition for a Content Rule. This condition will evaluate to true when attibuteA and attibuteB of a dexterity content type are filled out (you can assume they are text inputs on the form). I'd like this to be tested whenever these inputs are modified. How can I do this? I cannot find any examples of TALES expressions for Content Rule conditions.
I have never used TALES, TAL, and don't know how to access attribute values from this context.
If you have any questions, please ask.
Thank you for your help.
