How to save content typed in textfield only as lowercase in repository?
Suppose we have a textfield in a component dialog. Irrespective of how enduser enters the data in the textfield, lower/mixed/upper case, it should always be saved as lowercase in the repository.
You have 2 options:
* Server-side: Implement a SlingPostProcessor to change the data to lowercase before it is persisted (see http://sling.apache.org/apidocs/sling6/org/apache/sling/servlets/post/SlingPostProcessor.h tml)
