After deploying a custom filter and ExportDelegate class, it appears that the issue is that the response is committed before it gets to the ExportDelegate. I'm using Struts and Tiles, but I can't find any specific application code that would cause the response to be committed early. Has anybody run into this and found a solution for it?

Subject: RE: [displaytag-user] Exporting issues with TableDecorators
Jorge,
Thanks! I think that was indeed the root cause of my error messages. I added the media-specific decorator parameters to the table, and the errors went away.
I seem to still be experiencing issues with exporting, however - and they are likely unrelated to this initial issue. The logging doesn't indicate there are any errors, but I get a blank page (no content) when trying to export. This is consistent, regardless of export type (CSV, Excel, XML). I set the logging to debug for the org.displaytag package, and it tells me that the filter is active:
2006-07-05 16:08:20,330 [scheduler-3] DEBUG - org.displaytag.filter.ResponseOverrideFilter.init (org.displaytag.filter.ResponseOverrideFilter.java:104) bufferParam=null
2006-07-05 16:08:20,330 [scheduler-3] INFO - org.displaytag.filter.ResponseOverrideFilter.init (org.displaytag.filter.ResponseOverrideFilter.java:108) Filter initialized. Response buffering is enabled
2006-07-05 16:08:20,330 [scheduler-3] INFO - org.displaytag.filter.ResponseOverrideFilter.init (org.displaytag.filter.ResponseOverrideFilter.java:108) Filter initialized. Response buffering is enabled
When a request is processed for the initial list, it tells me that it is skipping the export process because the flag parameter is not set (good):
2006-07-05 15:59:39,002 [jrpp-0] DEBUG - org.displaytag.filter.ResponseOverrideFilter.doFilter (org.displaytag.filter.ResponseOverrideFilter.java:122) Filter has been called, but PARAMETER_EXPORTING parameter has not been found.
When I export the list, it appears that the filter has done it's job:
2006-07-05 16:09:20,502 [jrpp-3] DEBUG - org.displaytag.filter.ExportDelegate.writeExport (org.displaytag.filter.ExportDelegate.java:72) Filter operating in buffered mode.

<column>Farmer</column>
</row>

</row>
</table>
}
2006-07-05 16:09:20,502 [jrpp-3] DEBUG - org.displaytag.filter.ExportDelegate.writeExport (org.displaytag.filter.ExportDelegate.java:78) {contenttype=text/xml, buffer=true, filename=, body=<?xml version="1.0"?>

</table>
}
Yet, somehow, at the end of the process, I get no response content.
Any ideas what I may be doing wrong?
Thanks!

Todd,
Sounds like issue 298, http://jira.codehaus.org/browse/DISPL-298.
I've posted a patch there, along with documenation.

Hi,I am using DisplayTag 1.1, and I have created table decorators so that I can format the data in the columns and provide links (with multiple parameters in the query string). Everything has been going well, until I try to export the data in any format. I'm using Struts, and have implemented the filter per the DisplayTag documentation.The issue appears to be that the export process is using the undecorated domain object rather than the custom TableDecorator I created. The error I see in the logs is:006-07-05 14:52:16,893 [jrpp-0] ERROR - org.apache.struts.taglib.tiles.InsertTag.doEndTag (org.apache.struts.taglib.tiles.InsertTag.java:922) ServletException in '/WEB-INF/jsp/templates/SearchTemplate.jsp': ServletException in '/WEB-INF/jsp/tiles/SearchResult.jsp': Error looking up property "linkedEntityCode" in object type "com.mycompany.domain.AccountDetails".
jrun.jsp.runtime.UncaughtPageException: Unhandled exception thrown from /WEB-INF/jsp/templates/SearchTemplate.jsp:4I've added the following line to my display.properties file, but it had no effect (and from the documentation, I understand that this is the default value as well):export.decorated=trueAre there any suggestions on how to address this?Thanks!Todd FarmerUsing Tomcat but need to do more?
