... but I still couldn't get
filter=$$ITEM_CHECKED(True) to work!
Also, it appears that you must delete the XL target databases to ensure xAnt will run... it looks like it may check the date of the Ant db file, and will not make changes to the XL database if nothing in the Ant db has changed
So deleting the Xlobby target databases will force xAnt to recreate the databases
.... in my opioion, it should also check to see if the xAnt ini file was changed
