Embedding reports in a JSF 2.0 facelet.

llazzeri

I can successfully embed a Birt report in a JSF 2.0 facelet via a tag
<h:outputText escape="false" value="#{...}">
whose value is the String resulting from an embeddable HTML Birt report.
This technique fails when the report is provided via ajax and it contains some javascript (such as, for example, a chart with interactivity).
The reason of failure is that JSF inserts the ajax response in a XML file, enclosed in a CDATA section.
If the report contains some javascript, Birt encloses it in a CDATA section.
The result is an XML file containing two nested CDATA sections, which is wrong.

Any idea to solve this issue will be really appreciated.
Thanks in advance and regards,
Livio

Can you open an enhancement request in bugzilla for this?
BTW have you tried:

Jason, 
thank you for your reply. 
 
JSF4BIRT supports JSF 1.2 only and there are no plans to support JSF 2.0. 
 
As far as my problem is concerned, I am not sure that it is a Birt's issue. It could be an issue of Mojarra, which should take care of eventual CDATA sections in the HTML fragment. It would be nice to see if MyFaces has the same problem. I'll try when I'll have time. As a matter of facts, MyFaces addressed this problem, as is documented here: <a class='bbc_url' href='https://issues.apache.org/jira/browse/MYFACES-2835.'>https://issues.apache.org/jira/browse/MYFACES-2835.</a> 
From here I borrowed the idea to transform the nested CDATA in two adiacent CDATA, with just one simple method call: 
embeddableHtml = embeddableHtml.replace("]]>", "]]><![CDATA[]]]]><![CDATA[>"); 
and it works fine! 
 
Jason, please let me know whether you think still appropriate to post this on bugzilla. 
 
Best regards,

Nice work around. I would still like to get it recorded in bugzilla and put in your work around. The bug may get closed but at least it will be in for others. Do you mind?

The link to MyFaces in my previous post was incomplete. The right one is <a class='bbc_url' href='https://issues.apache.org/jira/browse/MYFACES-2835'>here</a>

Hi Livio, 
 
We are currently investigating exactly this (using BIRT with JSF 2.0). 
Were you able to successfuly integrate BIRT into JSF 2.0 and if so could you share 
some information on how you went about this? 
 
Thank you kindly.

sakkie6yster, I wrote up a blog on how to use JSF 2.0 and BIRT, <a class='bbc_url' href='http://www.birt-exchange.org/org/forum/index.php?app=blog&module=display&section=blog&blogid=45&showentry=442'>take a look here</a> and let me know if you have any questions.
