Rational for this is that the number renderer expects a number
input, not HTML, but if non-numeric input is given the value is just
returned (now escaped) - for example an empty string.
- I just updated my PHP and HTML Tidy was not installed which resulted
in the examples in the dist repo all being rewritten unfortunately.
This should stop that happening again.
- If d or objectRead were truthful then the row's data object would be
replaced with an empty object. This was one shortcut in code too many!
- Relates to thread 29530 with thanks to idleog.
