Can not access PGV set in onFetch of dataset, later in onPrepare of TextItem.

<p>This is a simple example where I am setting PGV with onFetch method of dataset.</p>
<p> reportContext.setPersistentGlobalVariable("myvar2","Hi123");</p>
<p> </p>
<p>Then trying to access it in onPrepare method of TextItem.</p>
<p> reportContext.getPersistentGlobalVariable("myvar2");</p>
<p> </p>
<p>I have made sure that there is element in report (above TextItem), which is tied to the dataset so that onFetch method is called.</p>
<p> </p>
<p>However it returns null in textItem. What is wrong here.</p>

<p>That is because the onPrepare method gets called before the onFetch. This video might help:</p>

<p>In your example, you could set the text of the text element in the text's onRender method using the following command:</p>
<pre class="_prettyXprint _lang-js">
var str = reportContext.getPersistentGlobalVariable("myvar2");
this.text = str;
</pre>
<p>The .setContent() method seems to only work in beforeFactory (or earlier) however a data set's onFetch is during factory which is too late for .setContent() and beforeFactory is too early for the variable set during onFetch.</p>
<p> </p>
<p>You could query the data set early to get its value using API code (<a data-ipb='nomediaparse' href='http://developer.actuate.com/community/forum/index.php?/topic/35930-running-a-query-in-the-initalize/?p=133369'>http://developer.actuate.com/community/forum/index.php?/topic/35930-running-a-query-in-the-initalize/?p=133369</a>) or set the value later on such as the onRender method example above.</p>
