Right. So you need to use the same query twice - once to assign ("true" or "false) value to _hasFormal variable and again for printing the data within the table. Use the condition _hasFormal=="true" on the table element and condition _hasFormal=="false" on the text element (that prints "NA").
i have done that...Here i am trying to print operations from rhapsody classes. So operation argument if not present should print NA and if it is there table will generate with values. So here what i observed that if any of the operation have argument and table print then the condition hasformal != "true" not working.
(Note: I cannt comment on you answer ie i am answering like this)
