Hi,

ResourceStreamResource with a null cacheDuration uses the application default, see ResourceSettings#getDefaultCacheDuration().

Thanks for the issue.

What about ResourceStreamResource? Why is cacheDuration null by default?

Thanks

Hi Marios,

you're right:
ExportToolbar doesn't specify any cache information, so updates to the
data are not reflected in repeated exports.

We should improve that:

- no caching as default
- users should be able to change this easily

Can you create a Jira issue please?

Thanks
Sven

Hi all,

We have run into some problems when using the ExportToolbar the generated
file seems to be cached in some browsers so that user's don't get a new
version if the table contents change.

I think there should be a way to tell the ExportToolbar to call
setCacheDuraction(Duration.NONE) to the ResourceStreamResource that is
used
to serve the file.

There is also a related StackOverflow thread on this:

https://stackoverflow.com/questions/42602650/wicket-exporttoolbar-not-refreshing-on-table-update

We've actually run several times into caching issues with
ResourceStreamResource, and we had to explicitly set setCacheDuration to
none. I'm not sure if this is the intended behavior and if having a null
default value for ResourceStreamResource.cacheDuration is the right
thing...
Thanks
Marios
