Mark, thanks for the description of the trace function etc. I've played a
bit with it and it seems to work but not always. Have a look at the example
below: the first call to self~getdata correctly results in a trace message
but the second call to the same method, triggered by an expand action, does
NOT work and generates message Error 91.999: Message "EXEC" did not return
a result
I can't see what's wrong with this. Comment out the db~trace(.sqltrace~new)
statement and the problem is gone. Any ideas?

page1 = .page1~new(,,,"TreeView",,12)
ps = .propertysheetdialog~new(.array~of(page1))
ps~execute
::class page1 subclass userpspdialog
::method defineDialog
expose tree db
self~createTreeView(2000,10,10,self~cx-20,self~cy-20,"ALL
NODRAG","TREE_VIEW")
db = .ooSqliteConnection~new("test.db")
db~trace(.sqltrace~new)
self~getdata -- This is working
::method initDialog
expose tree db
tree = self~newTreeView(2000)
self~connectTreeViewEvent(2000,"EXPANDING","onExpanding")
tree~add("Root",0,,,1)
::method onExpanding unguarded
expose tree db
use arg id, hItem, currentItemStatus
reply 0
self~getdata -- This is NOT working
::method getdata
expose tree db
say db~exec("SELECT * FROM DATA;")
::class sqltrace
::method traceCallBack
say arg(1)
return .ooSQLite~OK
::requires "oosqlite.cls"
::requires "oodialog.cls"
