Specify objects to be save during a pfc_Save event
The pfc_Save event uses the Window control array (by default) to get what are the objects
to be updated and in what order. You can use the of_SetUpdateObjects() function
to specify your array of objects to be updated. For example, the following will make sure that
dw_2 is updated before dw_1.
this.of_SetUpdateObjects({dw_2, dw_1})
The same function is used to include objects which are not self-updateable by default, like n_ds
for example. Be sure to call of_SetUpdateable(true) in the n_ds constructor.
