Hello, maybe can somebody help for the case explain below: I made a product called BOX In this product, I create two Zclasses: -one called Fiche -another one called acteur Zclass Fiche has a property called lesacteurs (lines) Zclass acteur has a property called nom (string) The content structure is like this: XXXRootFolder: -REDBOX: -Fiche1 -Fiche2 -Fiche3 -Allacteurs: acteur1 acteur2 acteur3 The property called lesacteurs in Fiche list selected Id's of acteur Zclass instance choose by user. Then I have for exemple the property lesacteurs of Fiche1 containig: acteurs1 acteurs2 In the render method of Fiche Zclass, I like to see the lesacteurs property but not the ID's of acteur Zclass instance selected but the PROPERTY nom of each instances. Help would be great great appreciated to solve this problem. Later I'll have thousands of acteur instances, then I think the best way is to use Zcatalog, but I don't know how to call the nom property from the render method in Fiche Zclass. Merci beaucoup par avance !!
