Status: Unverified
FACT(s) (Environment):
Progress 8.x
Progress 9.x
SYMPTOM(s):
FRAME-FIELD returns an unexpected value.
Application uses NO-FOCUS buttons.
In the CHOOSE trigger for the NO-FOCUS button, FRAME-FIELD is not the expected value.
FIX:
FRAME-FIELD is an obsolete function and may not work properly with event-driven programming.
The best option is to use the FOCUS handle, in particular FOCUS:NAME if the same functionality as FRAME-FIELD is required. The FOCUS handle can provide alternatives for other v6-style functions, for example:
V6 style FOCUS handle
----------- ---------------
FRAME-FIELD FOCUS:NAME
FRAME-DB FOCUS:DBNAME
FRAME-FILE FOCUS:TABLE
FRAME-INDEX FOCUS:INDEX
Please note that for NO-FOCUS buttons, the FOCUS handle points to the widget where the cursor was in before the user clicked on the button, even inside a CHOOSE trigger (in CHOOSE triggers, the FOCUS handle usually returns the same as SELF).
