: <copyField source="field_A" dest="clubbed_text"/> : <copyField source="field_B" dest="clubbed_text"/> ... : <copyField source="clubbed_text" dest="clubbed_string"/> : : Is the copyField valid specified in BLOCK-4? It seems it is not : populating the clubbed_string with the values of field_A and field_B.
copyFields aren't chained together -- supporting that is "hard" and can lead to infinite loops, so each copyField src is copied direclty into the dest (without checking to see if the "dest" is the src of any other copyFields) : Do I need to populate clubbed_string by explicitly copying field_A and field_B directly to it? yes. -Hoss
