I ran into something related to this. If you just want to return data in the
“Form” object — you are not passing any data into the form — you must create
the object before you call DIALOG.
So this fails:
C_OBJECT($formData_o)
DIALOG(“myForm”;$formData_o) // somewhere on myForm you do this
“Form.result:=“Continue”
// get values set in the myForm that were assigned to “Form” object
if($formData_o.result=“Continue”)
// this never executes
end if
But this works:
C_OBJECT($formData_o)
$formData_o:=New object
DIALOG(“myForm”;$formData_o) // somewhere on myForm you do this
“Form.result:=“Continue”
// get values set in the myForm that were assigned to “Form” object
if($formData_o.result=“Continue”)
// this never executes
end if
$formData_o now has all the properties you set in myForm assigned to “Form”
object. Like “Form.result:=“Continue”
You have to get $formData_o instantiated — if that’s the right word — in the
method before you pass it into the DIALOG command because it is passed by
reference. Then when you use the “Form” function in myForm it will update the
correct object that you created with the "$formData_o:=New object” line of
code.
