After updating to the latest jenkins version (v1.536) i get this error when saving a project which has the email-ext plugin enabled

EDIT:

It looks like it has to do with missing options in the config (the config hasn't changed for weeks now..) but with a litle bit of guessing i found what options were required. So maybe a fix for this issue could be to have required fields and give the user feedback on what fields he has to fill instead of this raw error

New: After updating to the latest jenkins version (v1.536) i get this error when saving a project which has the email-ext plugin enabled

EDIT:

It looks like it has to do with missing options in the config (the config hasn't changed for weeks now..) but with a litle bit of guessing i found what options were required. So maybe a fix for this issue could be to have required fields and give the user feedback on what fields he has to fill instead of this raw error

Be aware that the plugin is only tested with the most recent LTS release, any releases after that have not received any testing and so there are possibly breaking issues in the core. Please post the config.xml that is "missing options".

I found that the problem is with the mail trigger, so i add a mail trigger and save (that works correctly) but when i open my config after that it show an empty line for the build trigger and it throws the error above when saving

We have the same problem. Sometimes save works and sometimes we got the above described error. I found out that config.xml has <null> in <configuredTriggers> and therefor is not able to run the job. If I put in the correct values manually and reload jenkins settings. Everything works fine. So I think its a problem of the job save mechanism.

Environment:
Ubuntu 12.04 LTS
Jenkins 1.5.36
Email-ext 2.35.1

I linked this issue to one that looks similar that was related to some new Stapler stuff in core, it is supposedly fixed in 1.536, but there may still be some issues.

Got this after upgrading Jenkins from v1.535 to v1.536 (and EmailExt plugin from v2.34 to v2.35.1). Looks like the same thing as JIRA-20030. Job configuration files end up with <null/> tags, in place of the prior content of the <configuredTriggers> tag. Causes NPEs, when you try to run the job.

OS:	Windows 2008x64

No, I don't think this is the same thing as ~~JENKINS-20030~~ at all. That was a change in the way that parameters were parsed from the job config page, this is completely different. I believe it has to do with changes that were made in 1.536.
