Cannot read property 'document' of null datajs.js

[former_member319141]

Hi,

I'm receiving an error and i'm trying to find its cause.

In this scenario i'm creating a JS view and inside the createContent function i'm creating some ui controls and an OData model.

my suspicion is that when i use the setModel, the call the the OData service is triggered before the control get a chance to render, but thats just a suspicion.

i've attached the error and the stack trace.

Help would be very appreciated.

Many Thanks,

Rafi

any idea?

[former_member184867]

Can you share the snippet ?

[former_member319141]

its a bit complex because the code is splitted around many files (and i dont have access to all of it)

but basiscally its something like this:

var cell12 = new sap.ui.commons.layout.MatrixLayoutCell({

  colSpan : 1

  });

  var lblChannel = new sap.ui.commons.Label("lblChannel");

  lblChannel.setText(sharedData.getLocalizedText("cust_search.distchan.lbl"));

  lblChannel.setDesign(sap.ui.commons.LabelDesign.Bold);

  cell11.addContent(lblChannel);

  var ddbChannel = new sap.ui.commons.DropdownBox("ddbChannel");

  ddbChannel.setModel(sharedData.getCustomerSearchModel());

  var oItemTemplate = new sap.ui.core.ListItem();

  oItemTemplate.bindProperty("key", "Distrchn");

  oItemTemplate.bindProperty("text", "DistrchnT", function(fValue) {

  return this.getProperty("key") + " " + fValue;

  });

  ddbChannel.bindItems("/DistChannelCollection", oItemTemplate, null, [ new sap.ui.model.Filter("Salesorg", sap.ui.model.FilterOperator.EQ, gadgets.sappopup

  .getParameters(context)[0].salesOrganization.getParameter("Salesorg")) ]);

sharedData.getCustomerSearchModel() does:

var x = new sap.ui.model.odata.ODataModel(sServiceUrl, dataTypeJson);

  x.setCountSupported(false);

return  x
