[libreoffice-users] Bug\feature in LO Base master\slave form linking

Hello!

  I'm trying to create a form with master\slave relation. My tables
linked to external PostgreSQL database, so I'm getting data for master
and slave forms from queries. I make the relation by choosing fields
in "Link with master table" and "Link with slave table" (I have
localized version so I don't know how it exactly named) properties in
subform's Property Editor. Subform's query is:

SELECT "invTypes"."typeName" AS "Name",
"invTypes"."description" AS "Description",
"invTypeMaterials"."quantity" AS "Qty",
"invTypeMaterials"."typeID"
FROM "EDB"."public"."invTypes" AS "invTypes",
"EDB"."public"."invTypeMaterials" AS "invTypeMaterials"
WHERE "invTypes"."typeID" = "invTypeMaterials"."materialTypeID"

Relation has to be build by "intTypeMaterials"."typeID" field, so I'm
choosing "typeID" for "table" intTypeMaterials" and "ProductID" for
master "table".

When I'm trying to open the whole form in view mode, I'm getting an
error: "Cannot load data. ERROR:  column reference "typeID" is
ambiguous at character 338; Error while executing the query".
If I look into the sent query, I will see that LO change WHERE clause
to '( "invTypes"."typeID" = "invTypeMaterials"."materialTypeID" ) AND
( ( "typeID" = :link_from_ProductID ) )'.
Both tables in query have "typeID" field, so server can't choose the
need one. And Postgres can't use an AS aliases in WHERE clause.

Is it possible to change the way of LO making relation's query or to
find an another way to solve my problem?

Thank you in advance!
