JointJS resetCells() not working! Getting an error: Uncaught TypeError: dia.Graph: cell type must be a string.

[yufeng....@gmail.com]

I have tried to add new cells into an existing graph by using graph.resetCells() method.

But I keep getting the same error : Uncaught TypeError: dia.Graph: cell type must be a string.

Here is my implement code:

<div id="paper" style="width:300px;height:300px;border:1px black solid">

</div>
      <button id="test"> Click me </button>
<script>
   var graph = new joint.dia.Graph();
   var paper = new joint.dia.Paper({
      el: $('#paper'),
      width: 800,
      height: 600,
      model: graph,
      gridSize: 1
   });

   var cell = new joint.shapes.basic.Rect({
                      position: { x: 50, y: 50 },
                      size: { width: 50, height: 50},
                   });

   graph.addCell(cell);


   $("#test").on("click",function(){
       var newcell = new joint.shapes.basic.Rect({
                      position: { x: 100, y: 100 },
                      size: { width: 50, height: 50},
                   });
       graph.resetCells(newcell);
   });

</script>

I'm hoping someone could help me out!

Thank you!

I solved this problem by changing

graph.resetCells(newcell);
to

graph.resetCells([newcell]);

input an array instead of single cell name.

I hope someone could edit this method description in the API. 

Thank you.

Hi,

thanks for letting us know. This was a bug in the implementation. The method ignored the cells if a single cell was passed in.

`resetCells(newCell1, newCell2)` // this works

`resetCells(newCell1)` // while this doesn't

Here is a fix: https://github.com/clientIO/joint/pull/544

Best,

Roman
