  Hey,

  We have a custom treenode cell that worked well in v9 until it just started to blow up upgrading to v11.
  
  Seems like the internal spreadjs code changed - where a property became a function.

  Not sure how to fix it…
  
  here is the code that blows up

  
  	TreeNodeCellType.prototype.processMouseDown = function (hitinfo) {
              var level = hitinfo.sheet.rowRangeGroup.getLevel(hitinfo.row);
              var hoffset = (level + 2) * this.iconSpace + hitinfo.cellRect.x;
              if (hitinfo.x < hoffset - 3 && hitinfo.x > hoffset - 21) {
                  var collapsed = hitinfo.sheet.rowRangeGroup.isCollapsed(hitinfo.row + 1);
                  hitinfo.sheet.rowRangeGroup.setCollapsed(hitinfo.row, !collapsed);
                  hitinfo.sheet.invalidateLayout();
                  hitinfo.sheet.repaint();
              }
          };
  
  

  the line with setCollapsed blows up with following error:

  self.direction is not a function. Line 81255

  Hello,

  Please have a look at the documentation given here for Custom cell type with latest version and make the changes accordingly:

  That does not remotely answer my question.
  
  Like stated the exception is thrown on the rowRangeGroup.setCollapsed line which has nothing to do with the processMouseDown to which you link points to.
  
  The exception happens in rangeGroup code, and apparently in the use of outline column types.

  Anyways for someone else reading this.
  
  SP11 has a new feature - “Outline column”, so instead to trying to fix my custom implementation of the treenode cell (above code) - we will just swap out to use the Outline column to do that same thing.
