I have set in struts2 the property `"struts.multipart.maxSize=524288000"` so I can limit the overall upload size to that size. When I upload 2 files that exceed that limit, an exception occurs from the FileUpload interceptor

```
org.apache.commons.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (718551153) exceeds the configured maximum (524288000)

```

But the code does not reach the action with error so that I can return ERROR from the action and go to my custom error page and show the appropriate message. Instead it goes directly to application error and does not go to the action's method. 

Any suggestions on how to return "ERROR" so I can get the proper redirection?
