When creating a new page component in AEM, the parsys has a height of 0 and cannot be used.
We had a requirement to enforce alt attributes on images. Sounds simple, just set the alt field to required. The problem is when you do that for components that use images, like Text & Image. If a user decides to enter text, but not use the image portion the ALT text is still required, and the alert for a missing field still appears. To fix this we add a function to the ‘validator’ property of the ALT Text field using CQs ExtJS.
