             Summary: DiskFileItem as request attribute creates problems
                 Key: OFBIZ-12016
                 URL: https://issues.apache.org/jira/browse/OFBIZ-12016
             Project: OFBiz
          Issue Type: Bug
    Affects Versions: Trunk, 18.12.01
            Reporter: Sebastian Berg


Hi,

while working on a custom project based on the 18.12.01 version, I noticed a problem with the request handling during a request-redirect-noparam if a DiskFileItem was involved.

So the situation for me is as follows: during the first request a file is uploaded. I choose a wrong format on purpose, which results in an error respond for that event. Nevertheless the DiskFileItem is set as request attribute together with the error message.

The request is finished and based on the controller configurations redirected to a second request.

While handling the second request the previous request's attributes get restored (RequestHandler.java line 733ff). This goes down into SafeObjectInfo.resolveClass() where an Incompatible class exception is thrown. I compared my custom project with the current development status and worked in the changes from commit 3f60efb343a11723aa56c1bc1f5afac3a2f26e9f in OFBIZ-10837.

While this fixes the issue with the incompatible class exception it also makes it impossible to retrieve any attributes from the first request. Therefore my error message cannot be shown.

Is there a way to fix it or is it otherwise necessary to always set "fileItems" as request attribute as added in -OFBIZ-11246-?
