Hi John,
Forgot to mention that results were from IE.
The JQuery selector used was generated using Tellurium, so maybe there
is some tuning to do.
It's probably inserting the "*" because of the abstract container in
the ui module
ui.Container(uid:'coupon',clocator:[:]){
Table(uid:'table',clocator:[id:'MVContentPredictionsTable']){
Container(uid:"all",clocator:[:]){
}
}
}
If I remove the "*" then things are much faster.
In all cases the getText command does not return anything, although
the XPath version does.
