Migrating a project to PowerBuilder 2021 - getting "mixing array and non-array in assignment statement" error

Question

I have migrated a project from PowerBuilder version don't know to PowerBuilder version 2021. While regenerating one the windows in one of the libraries; I get an error that says: "Mixing array and non-array in assignment statement". Tracing this error in the open event of the window takes me to this line(s):

1. parm = message.PowerObjectParm ...
2. parm.postevent("some event") and in the "clicked event" of a button I have this parameter used, too:
3. parm.triggerevent("some event")

in line one I get this error: "C0070: Mixing array and non-array in assignment statement." line 2 this one: "C0068: Illegal use of array in expression" and line 3 the same as #2: "C0068: Illegal use of array in expression"

Any help would be really appreciated since I'm using a paid library to convert datawindows to excel files(with keeping the format) and now this library is useless.

p.s. parm is a global variable in the open event of the same window with the type of nonvisualobject.

Answer 1

Here is an example of this error

string ls_not_array
string ls_is_array[]

ls_is_array = ls_not_array

So somewhere in your scripts there is a method expecting an array and it's being sent a non-array (or vice versa) or some other type of assignment error exists.
