Tree table not refreshing on model change in IE

[Former Member]

We are using a tree table in a view used in MVC pattern.

I have single JSON Model defined as below:

this.oModel = new sap.ui.model.json.JSONModel();

var data = {

  dataSources:{

  CDSDataSource:false,

  ODataDataSource:true,

  DDICDataSource:false

  },

  destinations : [],

  serviceData : {

  root:[]

  },

  entityTypeName:"",

  connectionData : {

  root:[]

  },

  serviceMetaData: {

  root:[]

  },

  xmlMetadata:{

  root:[]

  },

  entitySetData:{

  root:[]

  },

  entitySetOperations:{

  root:[]

  },

  constructedServiceMetadata:{

  root:[]

  },

  filterableProperties:{

  root:[]

  },

  selectionString:"Select Systems / Source Types"

  };

this.oModel.setData(data);

I am using this model to bind multiple controls in the viewsuch as Tables, Treetable, Drop down, Textfields etc.

On one of the event of a control I am updating the part of the main model which was bound to the tree table. (which was initially an empty model), But after updating the model with values and doing the

that.oModel.setProperty("/serviceData/root",rootServiceNodes);

that.oView.getTreeTable().bindRows("/serviceData");

With this code my view would be initially empty and on the event the treatable refreshes and shows the data in boith Google Chrome and Mozilla firefox. But when tried the same thing in Internet Explorer the tree table will always be showing "No Data".

Please let me know if I have to handle tree table binding and re rendering with some different logic for IE?

Hi,

This issue is solved now.

The issue was nothing related to Treetable but instead of the JSON model.

Description:

Tree table once bound to a JSON model shows only first 100 nodes by default. To show more nodes we have to set the limit of the JSON model explicitly using setSizeLimit(value) method.

Since my JSON response was dynamic and it was quite huge I used setSizeLimit(Number.MAX_SAFE_INTEGER ) and this was the culprit as Number.MAX_SAFE_INTEGER  is not supported in IE and hence my JSON model was not reacting properly and hence the problem in UI.

Solution use setSizeLimit(<valid_value) with some valid value for ex: 99999
