Linkage and updates

[Annelize]

Hi guys

I'm hoping somebody could shed some light my following problem.

- I have master / detail datawindows set up through linkage.
- I made both the master and detail updatable through Rows / update properties.
- I can preview the dw, make changes and saves it without a problem.

But:
- I’ll run the application and make changes in my child.
- Upon saving I call pfc_Save in my parent
- Then I get an error saying that the Datawindow does not have update capability.

Then
- I took the linkage OFF and made changes to the master.
- It worked perfectly without error.

So this tells me that the linkage is causing the problem.
Here are the code, setting up my linkage

//enable the linkage service for the master / detail datawindow
//master
dw_master.of_setlinkage(TRUE)
dw_master.of_setrowmanager(TRUE)

dw_master.inv_linkage.of_setupdatestyle(1)  //TOPDOWN
dw_master.inv_linkage.of_setupdateonrowchange(TRUE)
dw_master.inv_linkage.of_setconfirmonrowchange(TRUE)
dw_master.inv_linkage.of_setconfirmondelete(TRUE)

dw_master.inv_linkage.of_settransobject( SQLCA )

//detail
dw_detail.of_setlinkage(TRUE)

//link to the master and register related columns
dw_detail.inv_linkage.of_Setmaster( dw_sec_roles_master)
dw_detail.inv_linkage.of_Register("ROLE_ID","ROLE_ID")

//establish the action taken in the detail when row focus changes in the master
dw_detail.inv_linkage.of_setStyle(dw_detail.inv_linkage.retrieve)

dw_master.of_setupdateable( TRUE)
dw_detail.of_setupdateable( TRUE)

Can you think of anything that I might be missing?
Thanks in advance

Are you using the of_save method on the linkage service?
(dw.inv_linkage.of_save(0,TRUE) or similar?

No, I call the of_Save method of the window. That uses the of_Save() of w_master.
