I am trying to set a filter for an upload button which should support multiple extension some of which are compressed.

I am trying the following but it does not work

Button uploadButton = (Button) getFellow("uploadButton");

The problem is that it only recognizes .csv files while it ignores .csv.gz. A workaround is


but this is not optimal since it accepts any kind of .gz file

Any help is more than welcome

I tried your example in this example on ZK fiddle using Chrome and Firefox (on Linux Mint) http://zkfiddle.org/sample/2nga7fi/1-file-upload-multiple-accept-types

Both browsers work showing files of either extension.

Can you test if the example works for you as well? Which browser/version and OS are you testing with?

UPDATE: IE11: shows the behavior you mention, however there's nothing in ZK you can change to fix the browser's behavior, the same effect happens with a native input element

updated example -> http://zkfiddle.org/sample/2nga7fi/2-file-upload-multiple-accept-types

MS-Edge: doesn't support the accept property at all (until the next version based on chromium) https://caniuse.com/#feat=input-file-accept

Thanks for helping out.

I am currently using MacOS version 10.14.5. On Chrome and Safari it only accepts the .csv extension but not the .csv.gz

I think there's not much I can do about browsers and their varying behavior. If you find a working hack please post here so we can consider adding this kind of "browser support" to ZK.

I can confirm that Chrome on Mac 10.14.3 can't filter .csv.gz
