changing text of button nested in DW

[Le Dave]

Hi,

I have a DW grid style with a nested button in the detail band.
I try to modify the text of the button for 1 row (can do it for all rows).
I have tried many dot stuff without success, it GPFs on runtime:

//OK for all rows
dw_1.object.col_button.text = "Hello"

// Runtime error on all these:
dw_1.object.col_button[2] = "Hi"
dw_1.object.col_button[2].text = "Hi"
dw_1.object.col_button[2].object.text = "Hi"
dw_1.object.col_button[2].data.text = "Hi"
dw_1.object.col_button[2].dwo.text = "Hi"
dw_1.object.col_button[2].dwobject.text = "Hi"
dw_1.object.col_button[2].button.property.text = "Hi"

It apparently doesn't like the row [] thing.

I welcome any other idea...

It's PB 6.5.1.
