BPM Suite 6.4 Developer Guide at advanced queries chapter has a duplicated entry for "QueryParamBuilder". [1]

Instead of:

"QueryParamBuilder: represents dataset which consists of a unique name, SQL expression (the query), and source."

I think it should be:

"QueryDefinition: represents dataset which consists of a unique name, SQL expression (the query), and source."
