Hi All, my english language is very limited, i'm sorry. I have a PersonModel with some descriptions. One of it, descriptionAddress is based on MAToOneRelationDescription with componentClass: MAExternalEditorComponent and classes: ( Array with: MAAddressModel ) When rendering PersonModel asComponent for the descriptionAddress the system display the relative low priotity description near the Remove and Edit buttons. I need to dispaly more data near the button. I have add, to the descriptionAddress definition the: reference: ( MAAddressModel descriptionCity, MAAddressModel descriptionRegion) but d'ont work well. The same problem i found in MASingleOptionDescription where reference: d'ont work. For MASingleOptionDescription i have solve with optionsAndLabels: In the MAToManyRelationDescription the reference: define the data to display for any item. I think same behaviour in MAToOneRelationDescription and MASingleOptionDescription but i wrong. ?! My question now is: how i can display some data near the Remove / Edit buttons relative to the MAAddressModel instance. Cheers, Dario
