Retrieve edited tableview in OnInputProcessing

Hi,

Is there a tutorial or an example on how to retrieve the edited contents of a tableview in the OnInputProcessing event? I have a table which is a mixture of checkboxes and input fields, and would like to retrieve the contents after the user has made modifications.

Using the CL_HTNLB_MANAGER=>get_data method I can retrieve the tableview. Then, I can find the edited contents of the fields by creating a loop with my_tv_data->get_cell_value. However, I have to dynamically construct the field names, and keep track of columns and rows...

I'd like to retrieve the modified table contents straight back into the same internal table I used for the tableview display in the first place. Is there a simple way of doing this?
