I posted this to the PrimeFaces user forum but I think they are too busy to look into it, so I thought I would try here.
I have server-side string that has markup in it, so when I want it rendered I do this:
<p:panel>
<f:verbatim>
开发者_如何学JAVA #{daBean.markedUpString}
</f:verbatim>
</p:panel>
This works fine, but not if the same tag is used inside a p:dataTable -- either with or without the p:panel enclosure. What gets rendered is a div class="ui-dt-c" element with nothing in it. To test, if I take out the f:verbatim tag the marked-up text gets escaped and rendered.
I don't know if this should be considered a bug or not, but does anyone know of a work-around for this? This is with PrimeFaces 3.0.M3.
The <f:verbatim>
tag is intented to hold plain text/HTML, not JSF components nor EL expressions. The tag is a leftover from JSF 1.0/1.1 ages when it was not possible to inline plain text/HTML between JSF components. The tag is deprecated in JSF2. You do not need it anymore.
Your concrete functional requirement is thus displaying some HTML string from a managed bean unescaped. For that you should use <h:outputText>
with escape="false"
.
<h:outputText value="#{daBean.markedUpString}" escape="false" />
