I have a datagrid with an arrayCollection data provider. On a button click, I call a method to update the dataGrid. Some of the cells in the datagrid are supplied by comboBoxes and Numeric Steppers. The following are the problems that I am having:

1. When using the itemRenderer="mx.controls.NumericStepper", a numeric stepper is deployed into the datagrid as intended. But the maximum value becomes 10 and does not keep the maximum value of the original numeric stepper (i.e, any values of more than 10 will be changed to 10 when placed in the datagrid). How do I get the numeric stepper into the datagrid with the original maximum value?

2. When using the itemRenderer="mx.controls.ComboBox", an empty combobox is sent to the datagrid and not the comboBox populated with the original choices (with the user's choice the one selected). Note that if I use itemRenderer="mx.controls.TextInput", the user's choice populates the datagrid cell but it is only text and not the combobox. How can I get the original comboBox (with the user's choice selected) into the datagrid cell?
