$.widget.prototype._trigger is undefined
<p>I am trying to do drag and drop functionality. </p>

<p>When i use the below code <strong>i am getting an error and none of the js are working..</strong></p>

<pre><code>  $("#lock-content").addClass("set-draggable").draggable({
    cursor: 'move',
    helper: 'clone',
    revert: true,
    iframeFix: true,
    tolerance: "pointer",
    cursorAt: { left: 5 }
  });
</code></pre>

<p><strong>My error message is from ui.draggable.js?6 (line 386)</strong> </p>

<blockquote>
  <p>$.widget.prototype._trigger is undefined</p>
  
  <p>return $.widget.prototype._trigger.call(this, type, event, ui);</p>
</blockquote>

<p>jquery version 1.3.2</p>

<p>jquery ui verison 1.7.3</p>

<p>Why this issue is occurring and what is the solution for this issue.</p>

<p>I know it's a broad issue and FYKI i don't need an exact answer.. Instead it will be very helpful if you point any possibilities to resolve.</p>

<p>thanks in advance...</p>
