Thanks everyone for the prompt replies. With lots of commenting out
sections and trial/error, I found the problematic constraint. I had a
constraint inside a class that was based upon an array. The array is defined
in the class such as this:
<attribute name="range_array" type="expression" value="$once{new
Array()}"/>
The constraint was like this:
<view visible="${classroot.range_array.length>1}">
This was the point of failure. To resolve, I made an attribute that held
the current value of the array's length. I then modified the constraint to
use this attribute value instead, and it works! Problem solved!
