Lukasz Lenart commented on WW-4687:
-----------------------------------

It would be good to do it with all the interceptors, some generic mechanism to allow inject expressions.

> 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.
