TreeGrid with multiple children nodes

[prathap]

Hi there,
I am trying to display multiple child nodes in a treegrid. setChildrenField api takes only one node name as children. In my structure I have more than one node name which should be displayed as children. Is it possible to display with treegrid. Any ideas or suggestions will be helpful.

Here is a sample of my json input where i want to display both the nodes under BOM and Alternates as children in the tree to the parent 12345678.

{
"Number":"12345678",
"Name":"Test Name,
"BOM":
  [
    {...},
    {...}
  ],
"Alternates":
  [
    {...},
    {...}
  ]
}

Thanks,
Prathap

Here is the datasource code that I am using.

public BOMJsonDS(String id) {

    setID(id);
    setTitleField("Number");
    ....
    ......
    setChildrenField("BOM");
    setChildrenField("Alternates");
    .....
}

obviously it only takes last call of setChildrenField to use as child nodes.
I would to like to do something like
setChildrenFields("BOM","Alternates")
Not sure if it is possible by extending TreeGrid and overwriting a method. Any suggestions will be helpful.

I am wondering what is the implemenation class for TreeGrid Widget which generates the final html from the configurations.
I am trying to see if I can extend that class and achieve my requirement, to display children using 2 or 3 different field names.

Thanks,
