I use SmartGWT 3.0 power edition
And I try to have following logic
1. to have a combo box "listGridItem" to select the list grid setting
2. and after choose the change the combo box value, it will reload the datasource and fresh the data
3. but I find that after datasource reset and data fetch the previous field level setting is also reset, for example in the following code that I set the empty cell value "--", and it disappear when we change the datasource.
4. also when I want to change the field config and fetch data, it also cannot effective (for example I set the Header hover of the field "units" in my sample code)
Is what we found in 3 and 4 a valid behavior, how can I refresh the data with new field level setting at runtime?
