Issue: null value of manually assigned property is treated "null" string I tried to create event rule for click tracking of "a" tag which has specific property, but the rule fired even on all other links.I investigated it and found SL.propertiesMatch function has a procedure might cause unintended behavior easily.I intend to assign propery "data-tracking" with any value at "condition" area in DTM and set "data-tracking" = .* (RegExp).Then I clarified it on staging website, every time i clicked anchor links, that rule fired.When links which does NOT have specified property are clicked, DTM searches "data-tracking" property and returns null.Then it checks if null(null) matches /.*/i (RegExp). It must be failed, but it returns TRUE because RegExp.test() method treats passed null as a string "null"!! SL.propertiesMatch = function(e, t) { if (e) for (var n in e) if (e.hasOwnProperty(n)) { var i = e[n] , a = SL.getElementProperty(t, n); if ("string" == typeof i && i !== a) return !1; if (i instanceof RegExp && !i.test(a)) return !1 } return !0 }
