Hi All, i have my ApplicationModel with some description. Now i'm interested to display a small table based on TableDescription and TableMode. I define the descriptionTable descriptionTable ^MATableDescription columnsLabels: OrderedCollection .......... rowLabels: OrderedCollection ............. selectorAccessor: returnTableModel beReadonly Now my problem is: i can't not know the rowLabels: OrderedCollection...... definition because it depend on the my istance of ApplicationModel. Questions: A) How i can dinamic update the rowLabels after the descriptionTable builder ? B) How i can dinamic update the data of the table ? Now when the data of the table change when press the save buttons the system create error : Input is conflicting with current modification. But the table is readonly. Any pointers would be greatly appreciated! Thanks! Dario
