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-?
