Email content rule problems

tregi

Hi,
i'm having some trouble using an email content rule on a space. I use the wizard to set the user who will receive an email when a new item is added to the space. It seems to work, but if i go somewhere else and then get back to edit the rule again i get a java.lang.NullPointerException. These are the exception's details:

Regarding the posted problem, i would like to add something that maybe can help.

The situation i have is the following:

1) one space with a content rule applied. This rule is the one described above, which causes the java.lang.NullPointerException (moves a doc into another space and sends an email to a specified user)

2) another space with a simplier rule which moves only the inbound docs somewhere else in the spacestore

if i login and try to edit the first rule i get the exception. Then, i go and edit the second rule. Everything works: i can see and eventually modify it. Now i go back to the first rule and….magically i can edit it too: the exception is no longer present.

Finally, i can also see from alfresco log file that, when the first rule is fired, a message like "Failed to send mail to null" is shown; so it really seems that for some reason the application can't retrieve the email address in some occasions.

Hope i've explained it well.

Thanks in advance for your help!!!

Hi,

You have indeed found a bug.

The MailHandler class used to initialise the wizard for edit is trying to access the current wizard before it's been fully initialised, hence the NullPointerException.

Once you've been into one wizard succesfully the object required has been setup which is why on your second attempt it appears to work. However, the wizard will be using the wrong object.

I have raised this in JIRA: http://issues.alfresco.com/browse/AWC-966 so you track the progress.

Thank you for reporting this.

tregi

Hi,

you're confirming what i supposed: something was wrong with the initialisation of the handler class.

Thanks for this and for all the rest of your work!!!!! By the way, you're doing an excellent job with this software.

P.S. : do you think it's the same bug causing the error "Failed to send mail to null" when the rule is fired?

gavinc

What does the rest of the stack trace say? Did you select an individual to send the email to? Does that individual have an email adrress set?

I presume you have an email server configured and running on the same machine as the alfresco repository?

heckle

I am having this issue on 2.0 also. I had three rules in a space, the last one being a mail rule. I got the java.lang.NullPointerException error. I restarted the tomcat server to see what would happen. I was able to delete the rule.

Is this a seperate bug?

gavinc

Sounds like a simialr problem, the best thing to do is raise this as an issue in JIRA.

melkor_kp

I obtain the same error as well with the last alfresco 2.0 release

melkor_kp

As I said I get a similar error, here is the complete output.
Please let me know it I am doing something wrong or is just
an Alfresco bug.

The error message in this case gives a clue "Failed to send email to null", means that for some reason there is no email address present to send to.

Can you verify that the user you are trying to send the email to has an email address set in their user preferences.

christian

hi,

I also have a problem with the email content rule. When I add only 1 or 2 users to the list erverything works fine, but if I add more I get this error

[org.alfresco.repo.action.executer.MailActionExecuter] Failed to send email to null
org.springframework.mail.MailSendException: Could not send mails: 554 Not allowed

com.sun.mail.smtp.SMTPSendFailedException: 554 Not allowed

I'm using Version: Community Network - v2.0.0

p.s. alfresco is really great

gavinc

OK, I have spent some time this morning investigating these issues. It seems we have a regression for the bug http://issues.alfresco.com/browse/AWC-966 which is explained at the beginning of this thread. It seems a merge has been missed along the line somwehere and the fix applied to 1.4 has not made it into the 2.x codeline.

I have applied the fix to the enterprise branch for 2.x, this should get merged to HEAD and mirrored in the next few days. In the meantime it's a simple fix if you want to apply it your local copy.

In org.alfresco.web.bean.wizard.WizardManager in the setCurrentWizard() method move the following line before the call to wizard.init()

this.currentWizardState = new WizardState(config, wizard);‍

As for the other reported issues where emails are failing to get sent, there is a red herring in the exception message. Where it says "Failed to send email to null", that was caused by a mistake in the error handling.

Change the catch block in org.alfresco.repo.action.executer.MailActionExecuter to read as follows:

String to = (String)ruleAction.getParameterValue(PARAM_TO);
if (to == null)
{
   Object obj = ruleAction.getParameterValue(PARAM_TO_MANY);
   if (obj != null)
   {
      to = obj.toString();
   }
}
            
logger.error("Failed to send email to " + to, e);‍‍‍‍‍‍‍‍‍‍‍

You should now see that it is trying to send mail to the appropriate users/groups.

This leads me to believe that the errors are coming from the email sender itself and not Alfresco. I have been able to successfully send emails to multiple addresses and groups without error.

What email server have you guys configured in? Could you possibly test sending email with this engine in a small test harness outside of Alfresco to verify that it is working.

christian

Hi,

the problem was the mailserver of my provider. I was able to send mails to 3-4 users, but when I added more I got the "Failed to send email to null" message. I configured my own mailserver and now everything is working perfect.

Hello,

I am still having this problem, and pardon the ignorance but I can't find either a way to fix this on my local machine (I can't find the code referred to), and don't see any mirrors with files newer than late February.

melkor_kp

I solved the problem without the patch.
The problem I had is common in ubuntu (I do not tried in debian ) with spring framework. I solved the problem as follows:

edit /root/.mailcap
delete -e illegal entry‍‍

With that is working properly. This solved my error explained in this threat.
I hope this would help the rest of you.

I've encountered this same issue and wanted to try to make this update manually but which file do I update? I'm a newbie to Alfresco and any help would be greatly appreciated.

dgarrison

We are having the same problem with the rules diappearing once they have been set. We want to apply Gavins suggested fix

"I have applied the fix to the enterprise branch for 2.x, this should get merged to HEAD and mirrored in the next few days. In the meantime it's a simple fix if you want to apply it your local copy.

In org.alfresco.web.bean.wizard.WizardManager in the setCurrentWizard() method move the following line before the call to wizard.init()

Code: Select all
this.currentWizardState = new WizardState(config, wizard);

but those files appear to be compiled source code. We do not have strong Java programming skills in house. Are we missing something simple. How do we do this?

Thanks
