UIXEditableValue compareValues change

[Gabrielle Crawford]

Hi,

I was planning on making a change to UIXEditableValue.compareValues. The 
details are here:

https://issues.apache.org/jira/browse/TRINIDAD-1489

I don't think this is an issue, but since this is some really core code 
that's run for form controls I thought I'd see if anyone has objections.

Thanks,

Gabrielle
