--- Comment #5 from Julien Nabet <serval2412 at yahoo.fr> ---
I added traces to compare the 2 ways of adding relationship:
1) From non primary->primary (which works)
ORelationTableView::AddConnection
ORelationTableConnectionData::SetCardinality begin
checkPrimaryKey m_vConnLineData.size()=0
checkPrimaryKey m_vConnLineData.size()=0
ORelationTableConnectionData::Update
checkPrimaryKey m_vConnLineData.size()=1
checkPrimaryKey m_vConnLineData.size()=1
ORelationTableConnectionData::SetCardinality begin
checkPrimaryKey m_vConnLineData.size()=1
checkPrimaryKey m_vConnLineData.size()=1
checkPrimaryKey m_vConnLineData.size()=1
ORelationTableConnectionData::SetCardinality Cardinality::ManyOne
ORelationTableView::AddConnection call addConnection


2) From primary->non primary (which doesn't work)
with:
@@ -61,8 +61,7 @@ ORelationTableConnectionData::ORelationTableConnectionData(
const TTableWindowDa
 {
     m_aConnName = rConnName;

-    if ( !m_aConnName.isEmpty() )
-        SetCardinality();
+    SetCardinality();
 }

ORelationTableView::AddConnection
ORelationTableConnectionData::SetCardinality debut
checkPrimaryKey m_vConnLineData.size()=0
checkPrimaryKey m_vConnLineData.size()=0

So in this last case:
no call to Update -> m_vConnLineData has a size of 0 -> checkPrimaryKey returns
always false -> SetCardinality lets m_nCardinality to Cardinality::Undefined
