Lukasz Lenart commented on WW-4687:
-----------------------------------
It would be good to do it with all the interceptors, some generic mechanism to
allow inject expressions.
> Struts 2 make fileUpload parameters dynamic
> -------------------------------------------

> Key: WW-4687
> URL: https://issues.apache.org/jira/browse/WW-4687
> Project: Struts 2
> Issue Type: Improvement
> Reporter: Alireza Fattahi
> Fix For: 2.5.x
>
>
> In a struts 2 application ... we use `fileUpload` interceptor to get file
> from user.
> The `fileUpload` has some configurations `maximumSize` , `allowedTypes` ,
> `allowedExtensions` that can be used as:
> {code}
> <interceptor-ref name="fileUpload">
> <paramame="maximumSize">200000</param>
>
> <param name="allowedTypes">text/plain</param>
> <param name="allowedExtensions">txt</param>
> </interceptor-ref>
> {code}
> Is it possible to make these parameters dynamic !? For example
> {code}
> <param name="maximumSize">${maxsize}</param>
> {code}
> and let the action set its max file size.
