Prior to 1.2, all the links generated by displaytag are Http Get only, which prevented it from being integrated into many web applications. Including ours. Those links includes paging/sorting and exporting links.
I had to solve the problem by using a customized TableTag along with custom javascript code. The solution was applied around the 1st week of December.
However, they must have forgot the export link - it's still get only... Another custom patch...
Well one day I'll have to contribute it back to the open source project. Too busy recently.

Hi Bhanwar
Here is what we did to make the export link 'post' aware:
1. In org.displaytag.render.HtmlTableWriter.java, in side method private void writeExportLinks(), change it to:
// Figure out what formats they want to export, make up a little string
Href exportHref = (Href) this.baseHref.clone();
if (this.tableModel.getForm() != null)
{
exportHref = new PostHref(exportHref, tableModel.getForm());
}
...
2. Add the following line to org.displaytag.tags.TableTag.java, just before the closing tag of the method protected void initHref(RequestHelper requestHelper):
baseHref.addParameter(TableTagParameters.PARAMETER_EXPORTING, "");
baseHref.addParameter(this.paramEncoder.encodeParameterName(TableTagParameters.PARAMETER_EXPORTTYPE), "");
3. You'll also need to disable a few unit tests related to these changes, I didn't bother fix them.
Let me know how this works for you! Cheers.
Hi,
I made the JAR without validating the Unit Tests, but my display table is giving _jspx_th_display_005ftable_005f0 AS NULL in the below mentioned line.
int _jspx_eval_display_005ftable_005f0 = _jspx_th_display_005ftable_005f0.doStartTag();
org.displaytag.tags.TableTag _jspx_th_display_005ftable_005f0 = (org.displaytag.tags.TableTag) _005fjspx_005ftagPool_005fdisplay_005ftable_005fsort_005fsize_005frequestURI_005fpartialList_005fpagesize_005fname_005fid_005fexport_005fdecorator_005fclass_005fcellspacing_005fcellpadding.get(org.displaytag.tags.TableTag.class);
Please suggest how to go about it...
