testing again for fun!!!! also cos I wanted a fresh test. So I rememeber I'm testing in ie 7 yay and I get a nice helpful error message that I can't copy it reads
line : 133
char: 3
error: 'parentNode' is null or not an object
code: 0

then I submit and get the error. The email still gets sent and now has the correct details.

Colin was testing Assignment notification emails by going through the test at MDLQA-393

theres only yui with lines 133 and parentNode :

./lib/yui/2.8.2/build/selector/selector.js:133: return Y.Selector._getChildren(node.parentNode, node.tagName).length === 1;
./lib/yui/2.8.2/build/selector/selector-debug.js:133: return Y.Selector._getChildren(node.parentNode, node.tagName).length === 1;
./lib/yui/2.8.1/build/selector/selector.js:133: return Y.Selector._getChildren(node.parentNode, node.tagName).length === 1;
