Hi, I'm using the code below, to set the css class for an action column.
But even if the result is null, some elements are inserted by extjs.


Code:
getClass: function(v, meta, data) {        
      if (data.myDate < new Date())
            return null;
      else
            return 'insert';
  }
html:

Code:
<img alt="" src="data:image/gif;base64,R0lGODlhAQABAID/AMDAwAAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==" 
class="x-action-col-icon x-action-col-1   null">
