Hi,
i discovered this bug last year. It was registered under:
UID13 - ACI0100101: USE ENTITY SELECTION does not return the correct record in
selection in C/S-mode if the entity has been added with the method
'$selection.add'
Answer was:
Problem normally fixed with the Version : 18 build : 243746
------------------------------------------------------------------------
Bug Number: ACI0100101
This bug is reproducible with the following 4 versions:
- DEV (243285)
- 18 (243340)
- 17 R6 (243126)
- 17.3 (243342)
ONLY IN CLIENT/SERVER MODE
When creating an entitySelection with newSelection(), USE ENTITY SELECTION does
not work in C/S-mode. Example:
- Launch the database attached in Client/server mode
-Execute the methode 'P1'
C_OBJECT($selection)
$selection:=ds.T1.newSelection()
$selection.add(ds.T1.get(1))
USE ENTITY SELECTION($selection)
ALERT(String(Records in selection([T1])))
ACTUAL RESULT:
--> Records in selection([T1]) return 0
EXPECTED RESULT: entitySelection should not change
--> Records in selection([T1]) should return 1
