Hello, i have an interface that works when is in expression mode, but when i try to visualize in design mode, the following error displays:
"Could not display interface. Please check definition and inputs.Interface Definition: Expression evaluation error :
"
Just like that.

Hi Angel -
You're going to need to debug your interface expression to identify what it is about the state of your expression that design view doesn't like.
There are a limited number of ways that you can find yourself in these circumstances.
My recommendation is to comment-out your interface expression in small pieces until the interface will show in the design view. Then, start putting expressions back until it breaks again. This should help you isolate precisely where is the offending expression. From there, the task is to ensure that you're using *perfect* syntax and no shortcuts. Verify that what you've written is supported by the documentation.
This is frustrating, I know. It doesn't happen too often. Once you've cleaned up the code, you should be able to view the interface in both views.
Thank you so much Robert Shankin , helped me also to get out of this problem.
