I'm afraid I can't reproduce your problem.
What platform do you use?

Additionally, please could you try with the latest copy archiver plugin (0.4.3) built against Hudson 1.349?

Hudson is running on Windows XP SP2.

I upgraded Hudson to 1.350 and Copy Archiver Plug-in to 0.4.3, problem is still reproducing on my configuration.

I'll try to check is this issue is reproducing on clean installation of Hudson on my platform with only Copy Archiver Plug-in installed.

On my configuration on clean Hudson 1.350 installation with only Copy Archiver Plug-in additionally installed this problem is not reproducing.

But after installing Join plugin v1.8 this issue is arised again. So there is some conflict between Copy Archiver and Join plugins.

Looks like source of this problem is that in this configuration (Join and Copy Archiver plugins installed) both plugins inserts HTML tag <input> with same name "copyarchiver.sharedDirectoryPath" but different values. In my case value from Join trigger is empty and it is before <input> of Copy Archiver Plug-in, so when I save job configuration shared directory path is always overwritten with empty string.

So this is Join trigger bug (because it inserts duplicate <input> tags), is there any way to "move" or "attach" this bug to Join trigger component? Or new bug report should be created and this closed?

We are facing with the same problem after upgrading Hudson from 1.347 to 1.362. Build environment as follows:

Hudson ver. 1.362
CopyArchiver Plugin 0.4.3
Tomcat 6.0
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0.16-_09_mar_2009_04_02)
OS info:
sysname = HP-UX
nodename = ordu
release = B.11.23
version = U (unlimited-user license)
machine = ia64
idnumber = 3672085857
vmunix _release_version:
@(#) $Revision: vmunix: B11.23_LR FLAVOR=perf Fri Aug 29 22:35:38 PDT 2003 $

Our issue is resolved. It is because of a miss configuration. Somehow project information at "Job to aggregate" field is reset. We sorrected it an it runs fine with the configuration details I have previously posted.

Thanks

component changed to the join plugin according to latest rutsky's comment

While I understand this problem only appears when both join and copyarchiver are installed, the join plugin isn't really the bug. The solution is to either remove copyarchiver as an eligible join target, which the join plugin can do, or change the copyarchiver code so that configuration is more modular, allowing it to appear multiple times on the same page.

Removed deprecated dependency to that plugin in JENKINS-29196.
