<H2>Using Script Collector Events</H2>
This sample demonstrates how the script collector can be used to run a method before a page is rendered and when a page post action takes place.<BR>
<BR>A "Page Load Begin" event was used to initialize the contents of the first input field and checkbox. When "Page Load Begin" event is not used to initialize fields, they show up blank when the page loads.<BR>

Output set by a "Page Post" event when the submit button
is clicked:</B>
<h:outputText styleClass="outputText" id="text6"
value="#{requestScope.updown}"></h:outputText>
<P><hx:commandExButton type="submit" value="Submit"

</P>
<H4>How it works:</H4>
The script collector provides bindings to three methods in the page code file.
<BR>
<BR>
The "Page Load Begin" event runs before the page is rendered and is bound to the preRender attribute.<BR>The "Page Load End" event runs after the page is rendered and is bound to the postRender attribute.<BR>The "Page Post" event runs when a page is submitted and is bound to the decode attribute.<BR>
<BLOCKQUOTE>
<P class="code">Example:<BR>
<hx:scriptCollector id="scriptCollector1"
preRender="#{pc_ScriptCollector.onPageLoadBegin1}"
decode="#{pc_ScriptCollector.onPagePost}"></P>
</BLOCKQUOTE>
<P>To access these methods:<BR>
1. Click anywhere in a JSF page.<BR>
2. Open the Properties view, then click the <span class="tag">scriptCollector</span>
tag.<BR>
3. Click the Quick Edit tab. The three methods are displayed. .</P>
