Mail Task

joshjones

Hi,

In my workflow I am looking to use mail tasks as part of the process. However the recipient of the mail will differ from time to time. Can you use the "To" field in a more general sense or do you have to specify the exact recipient for each task.

Thanks.

Hi Jones,

Place a variable in the "To" field which you can then manipulate in each task.

Hi DarkRedd,

Can you provide me with a link or something that would give me more details about how to use variables?

Thanks

darkredd

You can declare and set a variable anywhere in you definition, say like this:

var mail_recipient = bpm_assignee.properties.email; ‍

and then reference it like this in your mail task:

${mail_recipient}‍

Hope this helps.

joshjones

I cannot seem to declare the variable in the definition. I also tried ${bpm_assignee.properties.email} within the 'To' field. Am I meant to declare the variable in the bpmn file or somewhere else entirely different?

darkredd

Post your bpm file here so we can have a look at it.

Hi Josh,

According to this post I have read, if you are using the Activiti engine bundled with Alfresco; your mail task will not work. Instead use a service/script task and invoke the mail action within that script. Here is the link: https://forums.alfresco.com/forum/developer-discussions/workflow/sendmail-activiti-not-working-03192012-0716

Hope this helps.
