Many of us have waited for it some time now. With the arrival of ADF 11.1.1.7 the Input components have got a new attribute: placeholder.
Use Case
Provide a prompt text inside an input component.
Usage
In order to use this feature just fill in the newly added attribute from the property inspector or directly in the source code.
On runtime it is properly rendered as placeholder-HTML5 Attribute.
Works on all modern browsers ;)
