Creating a new binding at runtime with a dynamic dataset fai

Hi all,

I need to bind my dynamic dataset, to show its content in a hierarchical ultradatagrid.

I found this article :

https://documentation.progress.com/output/ua/OpenEdge_latest/index.html#page/dvngp/prodataset-binding-example.html

But as the code runs the binding constructor, the application stop and no error are caught.

     rBindS = NEW Progress.Data.BindingSource(hDataSet, hBufTTCust, "*", "").

The difference between my code and the above example, is that my dataset and contained temp-tables are defined dynamically :

/* TABLE*/

DEFINE VARIABLE hSrcBuffer AS HANDLE NO-UNDO.
CREATE BUFFER hSrcBuffer FOR TABLE "ttTresoSoldesGroup".
CREATE TEMP-TABLE hTable.
hTable:ADD-FIELDS-FROM(hSrcBuffer).
hTable:ADD-NEW-FIELD ( "idGroup2", "character").
hTable:TEMP-TABLE-PREPARE(nomTable).

/* + TABLE 2 */ [...]
/* DATASET */

CREATE DATASET hDataSet.

hDataSet:ADD-BUFFER (BUFFER ttSoldesGroup:HANDLE).
hDataSet:ADD-BUFFER(BUFFER ttSoldesCompteBanc:HANDLE).
hRel = hDataSet:ADD-RELATION(BUFFER ttSoldesGroup:HANDLE, BUFFER ttSoldesCompteBanc:HANDLE, "idGroup,idGroup").

After creating and filling my dataset, I manage to control that it is filled with the data I was waiting for.

Anyone knows what I need to check to make it works, or how to get an error status about the reason it doesn't work ?

Thank you :)
