[Proposal] fix showDetail component with prompt facet on a PDA

[Piyush Hari <pi...@oracle.com>]

Hello,

The showDetail provides a means of toggling a group of components between being disclosed or undisclosed.

On a desktop, it shows up as linked hide/show icon followed by a linked disclosed/undisclosed Text.

If the prompt facet is present, this will be used instead of the disclosedText and undisclosedText attributes.

On a PDA, it shows up as a linked disclosed/undisclosed Text only. There is no icon.Since the prompt facet 
can be anything, we need to add a linked icon  (like the desktop) to enable user to toggle.

I propose to fix this. I will go ahead and create a JIRA for this.

Regards,
Piyush
