How to fire onChange event on ZK Textbox?
<p>In ZK, say I have a Textbox </p>

<pre><code>&lt;textbox id="tb"/&gt;
</code></pre>

<p>And then in java I do</p>

<pre><code>private Textbox tb;
tb.setValue("some new value");
</code></pre>

<p>I want that when I set this value, to trigger the onChange (or onOK) method of the textbox, as if the user has inputed the new text himself and pressed enter. </p>
