adding a 0-9 digit to a binary expression doesn't work

[globallyunique]

The implementation uses a regex to identify that when /0-9/ is entered that number should be added to the expression. Currently you can't just ender a digit, e.g., '1', you must enter '/1/'.

As an example of this or a related problem the 'Example' sample app allows entry of digits and strings but doesn't display the value entered until the view is changed.

This is about the custom action in the Example language. The regular expression is ignored and handled as a regular string.
