Re: NEWERA - beforerow -- supertable class

You are using the AFCL. Please locate doBeforeRow() in uNavSuperTable. This function updates the numbers displayed in the status area. In general, you should add an event to override (or supplant) functionality. For example; MyReallyBeforeRow event, theCurrentBeforeRowEvent, then MyAfterBeforeRowEvent would allow you to perform processes before ,and after the current beforeRow event and preserve the functionality of the "super" class (uHdrSuperTable, etc.).
