Android Question UltimateListView ExpandChildren Error

[Kiran Raotole]

I'm using Informatix UltimateListView https://www.b4x.com/android/forum/threads/lib-chargeable-ultimatelistview.22736/

Code :

ulv.SetChildren(ItemID, Children, "show")
ulv.ExpandChildren(ItemID)

If Children => ' (ArrayList) [100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110]'
It work properly.
If Children => '(ArrayList) [{FACCODE=A5, FPLACE=30}, {FACCODE=A5, FPLACE=30}, {FACCODE=A5, FPLACE=30kg}, {FACCODE=A5, FPLACE=30kg}, {FACCODE=A5, FPLACE=30kg}]'

on ulv.ExpandChildren(ItemID) its shows error:

Where I'm wrong?
or I'm using listview wrongly.
