> null can no longer be passed as parameter to interceptor
> --------------------------------------------------------
>
> Key: WW-5751
> URL: https://issues.apache.org/jira/browse/WW-5751
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 7.3.0
> Reporter: nikos dimitrakas
> Assignee: Lukasz Lenart
> Priority: Major
> Fix For: 7.5.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h

> Upgrading from 7.2.1 to 7.3.0 seems to have made a change so that null cannot
> be passed as a parameter to the ActionFileUploadInterceptor.
> I have an interceptor like this:
> {code:java}
> <interceptor name="myFileUpload"
> class="org.apache.struts2.interceptor.ActionFileUploadInterceptor">
> <param name="maximumSize">128000000</param>
> </interceptor>{code}
> That interceptor is then included in a global interceptor stack called
> myFileUploadStack.
> Later in some specific actions I want to set the maximumSize to null (no
> limit) and I do this:
> {code:java}
> <interceptor-ref name="myFileUploadStack">
> <param name="myFileUpload.maximumSize">null</param>
> </interceptor-ref>{code}
> This used to work until 7.2.1, but in 7.3.0 it gives an error:
> The upload validation policy could not be resolved, rejecting the file: file
> "test.pdf"; unresolved parameters: maximumSize
> Looking at the code and the release notes of 7.3.0, I can find that this
> probably relates to the changes made in WithLazyParams.java and
> AbstractFileUploadInterceptor.java (using a policy) as part of WW-5659. But I
> do not see in the release notes anything about this being intended or what
> the migration path would be. The javadoc of WithLazyParams.resolveInto()
> mentions null and empty value becoming unresolved, but not what to do about
> it.
> Obviously, I can set a very large number or create a second interceptor and
> interceptorStack to get around this, but I felt that this should be reported
> so that either it can be fixed, or it can be confirmed as the intended
> behaviour and if so, perhaps write something about it in the release notes
> (under Breaking changes) or in a migration guide.
