Count(data.table) did not work in Global Canvas


I have some problems:

An event pZapTable was made in “Global Canvas” which delete all records of a table.

However, it doesn’t work when I call pZapTable from one of a screen.

Having study the problem, 2 facts were observated:

  1. Counting records of a table inside “Global Canvas” into an App Variable does not work.
  2. Copying table–> in “Global Canvas” to a List does not work.

When pZapTable is moved into the above screen, it does work.

Can someone advice on my problem?
