GetLayout method not returning selections

[akeswani]

Hello,

I am using Angular4, and trying to get selections on QS app.

This is how I am calling createsessionobject first:

return new Promise((resolve, reject) => {
        var createSessionSelectionMsg = {           
           "jsonrpc": "2.0",            
           "id": 2,
           "method": "CreateSessionObject",
           "handle": parseInt(handle),
           "params": [
              {
             "qInfo": {
             "qId": "",
             "qType": "SessionLists"                   
              },     
               "qSelectionObjectDef": {}
              }
            ]
} .........

after that I am calling GetLayout

return new Promise((resolve, reject) => {

   var glayout = {

   "jsonrpc": "2.0",

  "id": 2,

  "method": "GetLayout",

  "handle": 2 ,//parseInt(handle),

   "params": []

}

...

The above two returns this result--

result:
qReturn:
   qGenericId: "13f471d2-ee35-480d-a965-a98d783abbc2"
   qGenericType: "SessionLists"
   qHandle: 2
   qType: "GenericObject"

result:

qLayout:

qInfo: {qId: "13f471d2-ee35-480d-a965-a98d783abbc2", qType: "SessionLists"}

qSelectionInfo:{ }

qSelectionObject: {qBackCount: 0, qForwardCount: 0, qSelections: Array(0)}

I am selecting a field value on the app, but the qSelections is not returning anything, don't know why.

am I calling the above correctly?

Can anyone please help me ?

Thanks!

marking it as correct answer ,as that was the initial problem.

For anyone interested in knowing the solution of further problems I was having with GetField and SelectValues not working for numeric fields, I came to know that the way Qlik works is that it creates list object on those fields behind the scenes. So ,instead of calling GetField and SelectValues, I am now calling CreateObject (the field is created as ListObject), and then GetListObjectData (to get all the values of that field), and then matching the selected values in that list returned and passing on to SelectListObjectValues to get it selected. At the end, just CreateSessionObject and GetLayout methods to display the selections. That made my selections applied on the screen when user clicks the link (which has selections passed in it).
