When you say that "only the key fields are passed in context to the child transaction" you are describing the default behaviour, but like most aspects of the Radicore framework this default can be overridden.

The string which is inserted into $selection by the parent task and then passed to the child task is constructed by taking a list of field names (by default the primary key) then combining it with the values from the selected record(s) to form a string in the format:

(field1='value1a' AND field2='value2a') OR (field1='value1b' AND field2='value2b')

This list of field names is initially populated by using the getPkeyNames() method, but it can be modified by inserting code into the _cm_getPkeyNames() method of the relevant table class.
