Terry,
At the moment Aware IM does not allow specifying default values for query parameter forms. However, it allows implementing a different workflow to enable the users to perform their business tasks. Specifically:
1) Define a query that uses default values (which can be static/dynamic/attribute values of objects in the context, etc.) to display a pre-filtered list to the users. For example, display only the active tasks. Define operations for the query results that the users are allowed to perform, either on individual or multiple items, in the query result list (View object, Generate document, Send email, Delete object, etc.)
2) The users start by running the query and see the pre-filtered results.
3) If desired, the users can further refine/extend/reduce the search using the standard functionality provided on the query result page. For example, see inactive tasks as well.
4) Once the users found what they wanted, they can click on one of the operations (for one or multiple objects if allowed) to perform the desired task.
Please let me know if this scenario would be acceptable.
