    <Portlet:Form . . . compatability

    This tag extends the struts form tag with a few powerful variations (note that struts tag that it extends has been modified and simplified) . Unlike Struts JAFFA has a more powerful event handling capability. By using hidden fields and event propogation multiple post events can be associated to a form.

    <Portlet:Form action="/samp_Comp"
    Contents of page.....

    In Browser

    <form name="sampAppForm" method="POST"
    <SPAN ID="sampAppForm_EntirePage" STYLE="display:block">
    Contents of page.....
    <input type="hidden" name="componentId" value="1">
    <input type="hidden" name="eventId" value="">
    <input type="hidden" id="dateTimeStamp" value="">
    <SPAN ID="sampAppForm_PushPage" STYLE="display:none">
    HTML contents of transition page.....

    JSP Code

    <Portlet:Form action="/samp_Comp"
    Contents of page.....

    How they work

    When this tag is encountered it writes inline HTML and javascript code. When the screen renders, the datetime stamp is written to the hidden field along with the componentID. If an event associated with a widget on the screen is fired, this event ID along with other information is written to the hidden field. The some background javascript fires off the applicable form[0].submit code. The guardedHtmlLocation code is used to make a span that is made visibile as the transition page when a post occours.
