LPS-29988 - Delete button never disabled on Shopping portlet's Coupons tab

Hey @AndyYang78,

Attached is an update for http://issues.liferay.com/browse/LPS-29988.

Can you test these changes to make sure I did not break anything?  I have made changes to all references in the portal that use a search container and a button for interaction.

NOTE: I was getting a build error when I turned jsp.precompile=on in my build.properties.  Can you take a look at that issue as well since it is backend related?

Please let me know if you have any questions.  Thanks!
