Hello, I'm posting here because I tried to implement solution proposed by Sergiu but it's not (yet) working ... (I'm using XWiki 1.5.2)
I want to have a "Database Tree List" property in a class of type FAQ (FAQs.FAQClass). I would like to use this property to link together a FAQ property "Category" with a "SubCategory", the subcategory being a db tree list (and the category being ...I don't know ...) So I first created a class "FAQs.FAQCategoryClass" with the class wizard, with String properties "ID", "VALUE" and "PARENT" Then, I created objects of this class as follows : Obj1 (ID='CAT1', VALUE='CAT1', PARENT='') Obj2 (ID='SUBCAT11', VALUE='SUBCAT11', PARENT='CAT1') Obj3 (ID='SUBCAT12', VALUE='SUBCAT12', PARENT='CAT1') Obj4 (ID='CAT2', VALUE='CAT2', PARENT='') Obj5 (ID='SUBCAT21', VALUE='SUBCAT21', PARENT='CAT2') Then I created only 1 property "Category", as a Database List type, and parameterized : XWiki Class Name = 'FAQs.FAQCategoriesClass', ID Field Name = 'ID', Value Field Name = 'VALUE'. When creating an object from my FAQ class, I get in "Category" field expected valued as a list : "CAT1", "SUBCAT11", "SUBCAT12", "CAT2", SUBCAT21". **** First question : what if I wanted to have only "CAT1" and "CAT2" in this list, in order to first select a category, and then the dependent subcategory ? Then I created a "SubCategory" property, as a Database Tree List type, and parameterized : XWiki Class Name = 'FAQs.FAQCategoriesClass', ID Field Name = 'ID', Value Field Name = 'VALUE', Parent Field Name = 'PARENT'. When creating an object from my FAQ class, I get a java.lang.StackOverflowError at com.xpn.xwiki.objects.classes.ListClass.getDisplayValue (infinite calls to addToSelect() ). **** Second question : what am I doing wrong ? **** Third question : maybe I don't even need the "Categories" field, and the tree is displayed directly in the select field ? (Don't know because could not make it succeed yet). Thanks for help, and sorry for long message ... :/ Regards, Jeremie -- View this message in context: http://n2.nabble.com/Help-wanted-on-the-database-list-class-property%2C-database-tree-class-property-and-the-Custom-Display-attribute.-tp508135p1337150.html Sent from the XWiki- Users mailing list archive at Nabble.com. _______________________________________________ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
