Description Ritesh Adval 2008-06-30 20:21:04 UTC 
aggregator operators require at least one aggregator function, when not provided it gives misleading errors.

ex:
time based aggregator:

"single attribute expression can not be found from GROUP BY attributes"

same problem with tuple based aggregator:

We need to have a tooltip or something above the expression field that says something like " Please type in an 
expression i.e. AVG(StreamInput1.field) etc. - the same message should probably appear when I don't type in an 
expression

work stated.
Comment 4 Ritesh Adval 2008-07-19 03:36:34 UTC 
fixed: 
Now message is more meaningful and clear:

"At least one expression is invalid for a GROUP BY query. The select expressions may only contain valid attributes 
used in GROUP BY clause and valid aggregate expressions."
