    Default Answered: Dataviews misconception

    Answered: Dataviews misconception


    Hello to everyone,
    I have a problem loading data in dataview. When I am trying to load data in panel using a template and static data everything is fine follow the link in jsfiddle.net: http://jsfiddle.net/anarchos78/dbCxS/5/
    Now, I am trying to do the same by using model, store, template and dataview. Nothing happens (no data loaded). Notice that I want to do the same using a proxy. I had already tried it but nothing was loaded. Follow: http://jsfiddle.net/anarchos78/KWT7E/4/
    In the second attempt you can see in the jsfiddle link that I had commented out a store with a proxy. The server’s JSON output is:
    Code:
    {"children":[null,{"member":[{
    "cls":"file",
    "text":"Gida Katsikis",
    "id":2001,
    "leaf":true,
    "biog":"The domestic goat (Capra aegagrus hircus) is a subspecies of 
    goat domesticated from the wild goat of southwest Asia and Eastern Europe.}],"DATASET":1}
    ]}
    The proxy’s reader root is “member”.
    What am I doing wrong?
    Thank you in advance,
    Tom

  2. With your data structure, you should config your reader root with "children[1].member"
    Code:
         proxy: {
              type: 'ajax',
              url: 'http://localhost:8500/MVC/Book_Ledger/app/cf_scripts/Members.cfc?method=getAllMembers&id=1',
              reader: {
                  type: 'json',
                  root: "children[1].member"
              }
          }

    Thank both of you (vietits and sskow). I marked vietits answer a best because this forum engine doesn't give the possibility to mark more that one answer as best, so i have chosen the first on the row. Thank you again.
