Seam <s:fileUpload> component shows all files, not only the file types set in the 'accept' attribute.

Solution Verified - Updated -

Environment

  • JBoss Enterprise Application Platform (EAP) 5.1.0
  • Seam 2

Issue

  • Seam <s:fileUpload> component shows all files, not only the file types set in the 'accept' attribute.

Resolution

According to Seam Reference Guide [1], the 'accept' attribute 'may not be supported by the browser'. That check to reject a file before uploading the content, if it does not match the appropriate content type, is left to the browser. Unfortunately, none of the browsers support this attribute. This is not a Seam issue. It's a browser feature, an attribute of the HTML input form, that is not supported by any of the browsers.
