Bonjour,

J'essaie d'exporter des données sous format excel en utilisant display table.

Or, j'obtiens ce message d'erreur que je ne comprend pas :
Code : Sélectionner tout - Visualiser dans une fenêtre à part

    Unable to reset response before returning exported data. You are not using an export filter. Be sure that no other jsp tags are used before display:table or refer to the displaytag documentation on how to configure the export filter (requires j2ee 1.3).
    Exception: [.TableTag] Unable to reset response before returning exported data. You are not using an export filter. Be sure that no other jsp tags are used before display:table or refer to the displaytag documentation on how to configure the export filter (requires j2ee 1.3).
    javax.servlet.ServletException: Exception: [.TableTag] Unable to reset response before returning exported data. You are not using an export filter. Be sure that no other jsp tags are used before display:table or refer to the displaytag documentation on how to configure the export filter (requires j2ee 1.3).
Pourriez vous me dire ceux que cela signifie, et comment solutionner mon problème ?

Je vous en remercie d'avance
