Hi Frantz,

But here is the explanation: <i>selection cardinality does not allow multiple selection</i>. check selection cardinality of datasource node which is bound to table. Seems like now it is 0..1 or 1..1.

Frantz,

Actually, besides your custom actions WD uses some service events when you are selecting rows in a table. Hence there is a roundtrip to server.

Key here is a message:

-

---

Caused by: com.sap.tc.webdynpro.progmodel.context.ContextException: Node(ATRView.Request_ATR2ViDocument_getAllCand.Response.Result): selection cardinality does not allow multiple selection

-

---

Node "Request_ATR2ViDocument_getAllCand.Response.Result" is a node used as Table dataSource, right?

So it seems that your Table UI control has explicit setting for selection mode "multiple" while node itself does not allow multiple selection.
