[ http://jira.codehaus.org/browse/DISPL-344?page=comments#action_74754 ]
andy pruitt commented on DISPL-344:
-----------------------------------
Here's the approach we use locally, ymmv. It's really pretty simple. (Pegboard
is our portal server.)
1) We have the export filter running against all portal requests.
2) All portlet urls are rewritten to be render urls by a RequestHelper
3) If an export is run, our local table tag will remove the export flag from
the render parameters after the export has been written
public class MyTableTag extends TableTag {
protected void writeExport(ExportView exportView) throws IOException,
JspException {
super.writeExport(exportView);
HttpServletRequest httpRequest = (HttpServletRequest)
pageContext.getRequest();
PegboardWindow pegboardWindow =
(PegboardWindow)httpRequest.getAttribute(PegboardWindow.CURRENT_WINDOW);
if ( pegboardWindow == null ){ return; }
Map params = pegboardWindow.getRenderParameters();
ParamEncoder encoder = new ParamEncoder( getId() );
params.remove(
encoder.encodeParameterName(TableTagParameters.PARAMETER_EXPORTTYPE) );
pegboardWindow.setRenderParameters( params );
}
}

> Key: DISPL-344

> Project: DisplayTag
> Issue Type: Bug
> Components: Export
> Affects Versions: 1.1
> Reporter: Bill Joy
> Priority: Blocker
> Attachments: Capture-05-18-00001.png
>
>
> When click on any of the Export options, the content of the portlet is
> replaced with the exported data.
> If do not add the "displaytag extensions" for JSR 168 portlet support, the
> export feature works correctly.
> I consider this a blocker because without the portlet extensions the
> "pagesize" table attribute has unacceptable behavior (so I have to choose
> which feature I prefer to enable).
