Just been asked this in a private message. Public discussion spreads the load and brings better harvests, so here's a first seedling.
Code:
tell application id "OFOC" tell default document -- SOME FOLDER, LET'S JUST GRAB THE FIRST WE SEE ... set oFolder to first folder -- ALL ACTIVE CHILD-BEARING PROJECTS ENCLOSED BY THIS FOLDER, REGARDLESS OF NESTING set refProjects to a reference to (flattened projects of oFolder where number of tasks > 0 and status is active) -- HARVEST THE PROGENY THEREOF (PERHAPS FILTERED) AS A LIST OF LISTS set lstTasks to flattened tasks of refProjects where completed is false -- FLATTEN THE LIST, IF NEED BE set lstTasks to my FlatList(lstTasks) end tell end tell on FlatList(lst) if class of lst is not list then {lst} else if lst ≠ {} then FlatList(item 1 of lst) & (FlatList(rest of lst)) else {} end if end FlatList
