I tried to use the frappe Multiselectdialog that is defined in the multi_select_dialog.js
In the debugger I repeatedly received an error and filtering did not work.
The error was:
Uncaught TypeError: this.dialog.fields_dict.allow_child_item_selection is undefined
The respective code line is line 154:
the field_dict does indeed not have a “allow_child_item_selection”. I changed the line to:
Now it is working.
I am not a programmer and found this out by trial and error. Is this a bug?
