passing parameter as group by key to agg.

[madhukar]

hi all,

i need to pass parameter value to agg grp by key.

it can done by using a transformer by a creating a column and
assigning parameter value to it.

any other way to get the same result?

No. You've found the appropriate technique. The Aggregator derivations do not support the use of job parameter references.
