I am trying to use the DisplayTag export to excel / csv feature. I am using Spring and Tiles. According to the DisplayTag documentation, I have followed the process recommended and implemented the filter to support tiles. I can view the data. However, the "Export to Excel" button does not work.
In my JSP, I have a search button and based on the input, a list is returned to the same JSP and rendered in a table. When I click on the "Export" button, it returns to the same page but now the table data is no longer visible and the export feature also doesnt work. On the logs, I dont see any exception but I see this message -
ExportDelegate, DEBUG, org.displaytag.filter.ExportDelegate: Filter is enabled but exported content has not been found. Maybe an error occurred?
