Service return parameter [message #858648]

I am a bit stuck trying to get the nested datagrid to work
I have a datagrid inside a datagrid and both grids get data from a service call.
My problem is that the service call runs after the grid is initiated and the first grid will be loaded by the data from the service call as the grid is accessible from the callback function. The nested grid however is not accessible from the callback function.
My problem would be solved if I could return two parameters from one service. One with data for the first grid and one with data for the nested grid.
I cannot find a way to specify two parameter for the return value like this for example "return(ARRAY1, ARRAY2);
I would be very greatful for any hint for how to solve this. Nested datagrid works fine, but I cannot find a way to get it working when I want do load data from a service call.

Hi Trond,

There are a couple of ways I can think of to handle this; 1. use out parameters or 2. create a wrapper record.

out parameter example:

function f1( p1 string in, p2 ARRAY1 out, p3 ARRAY2 out)
   p2 = new ARRAY1;
   //assign values to p2
   p3 = new Array2;
   //assign value to p3
end

Wrapper record example

record Wrapper
    a1 ARRAY1;
    a1 ARRAY2;
end
function f1(...)returns(Wrapper)

regards,
Joe

Thanks a lot Joe, you saved my day Smile

I tried the wrapper alternative and it works great (just changed to "a2 ARRAY2")
