Sometimes there are more than one fields in the same entity that are related to the same entity. In this situation, in the entity definition you have to specify a "title" attribute together with the rel-entity-name attribute. Have a look, for example, to the relations from the ProductAssoc entity: https://demo.hotwaxmedia.com/webtools/control/ViewRelations?entityName=Produ ctAssoc as you can see, both "productId" and "productIdTo" are related to the same entity "Product", so here you have to specify a title prefix: // ProductAssoc.productId --> Product.productId producAssoc.getRelatedOne("MainProduct"); // ProductAssoc.productIdTo --> Product.productId producAssoc.getRelatedOne("AssocProduct"); Jacopo [EMAIL PROTECTED] wrote: > I asked this question yesterday, but got no response.
