When opening a exported file that was exported using af:exportCollectionActionListener and using type excelHTML, with Microsoft Excel 2013, the following error is reported:-
"The file format and extension of 'xxxx.xls' don't match. The file could be corrupted or unsafe. Unless you trust its source, don't open it.Do you want to open it anyway?"
The af:exportCollectionActionListener is connected with a af:table for the data using the exportedId attribute.
This behavior is browser independed and seen in all browsers.
Is there a correct configuration for the af:exportCollectionActionListener to avoid this error ?
