CheckboxSelectionModel and ColumnModel issues
I have a simple gridPanel in a control that displays a single data field and a TemplateColumn with two radio buttons.
The goal is to process all rows selected. During that processing, different stuff is done based on the radio button selection.
There are two issues here.
First: I have found numerous examples on how to use checkBoxSelectionModel, but it doesn't work. I always get all rows returned when the grid is submitted. All the examples are using RowSelectSelectionModel, but this doesn't work either.
This is what I am using to get the data: Ext.encode(#{gpnlCards}.getRowsValues(true))
Regardless of weather I use true or false in the parm, I always get all rows from the grid.
Second: I have found how to get to the DataSource behind the grid, and its data, but no examples of how to access the TemplateColumn in the grid itself. Can someone point me to an example or explanation of how this works?
...some code removed for brevity
