3. Re: [jBPM 4] Mai templates context variables
tejjbpm Jul 24, 2009 10:26 AM (in response to gleenders)There are few problems:
1. Firstly the template named "task-assign" will be called you set notify="yes" in your task node. Only this template has access to #{taskInstance.name} not your custom template.
2. If you want to use a custom template then you got to set the event as "task-assign" inside yourFor example: <event type="task-assign"> <mail name="mailtest" to="fdds@jfgj.com"> <subject>Hello, there</subject> <text>Task instance name #{taskInstance.name} </text> </mail> </event>

4. Re: [jBPM 4] Mai templates context variables
gleenders Jul 24, 2009 10:51 AM (in response to gleenders)I'm aware that I'm using the "task-assign" template and indeed i have set notify to 'yes'. Everything works fine except for the taskInstance variable. For the moment I'm not trying to make a custom template.

5. Re: [jBPM 4] Mai templates context variables
tejjbpm Jul 24, 2009 10:55 AM (in response to gleenders)You did not get what I said. In the example you gave the name of your custom template as "task-notification". If you change that name to "task-assign" your taskinstance.name variable will work.
You are using custom template by changing the name of the template to "task-notification". The only system templates are "task-assign" and "task-reminder" which are by default present in jbpm.mail.templates. Whatever variables you want will work only under these two "SYSTEM DEFINED TEMPLATES" -

See my response to TejBPM below
@TejBPM
It has nothing to do with the templates, it has to do with the executionContext you are in. If you have a mail *node* like Gert initially had, there is no task instances there in the context. If you have an eventhandler and the event is task-assign, there *is* (afaik) a taskInstance in the execution context. -
7. Re: [jBPM 4] Mai templates context variables
tejjbpm Jul 25, 2009 3:48 PM (in response to gleenders)That is what I said Ronald. If he is using a custom template in the mail node he cannot access it . He has to change it to task-assign event to get the handle of it and I gave a code sample of how to achieve it!!!!

8. Re: [jBPM 4] Mai templates context variables
kukeltje Jul 25, 2009 5:06 PM (in response to gleenders)Ok, then it might have been the way you said it (and do it again now) that I tried to correct your statement (you were right about using an event instead of node)
And to make it 100% clear now, it has nothing to do with 'using a custom template in a mailnode' it has to do with 'using a mailnode' ;-) -
9. Re: [jBPM 4] Mai templates context variables
gleenders Jul 27, 2009 10:36 AM (in response to gleenders)Ok, I think a get the picture but i still have some problems.
First be aware that i'm using jBPM 4.
@TejJBPM:The only system templates are "task-assign" and "task-reminder" which are by default present in jbpm.mail.templates. Whatever variables you want will work only under these two "SYSTEM DEFINED TEMPLATES"
the current manual descibes the following:
Table 6.15. task elements
Element Multiplicity Description
notification 0..1 Sends a notification message when a task is assigned. If no template is referenced or supplied inline, mail support falls back on the template named task-notification.
reminder 0..1 Sends a reminder message at specific intervals. If no template is referenced or supplied inline, mail support falls back on the template named task-reminder
So when i use the following<task duedate="10 seconds" g="36,108,97,52" name="Visa Conseiller"> <assignment-handler class="be.axi.bpm.handlers.TaskAssignmentHandler"/> <notification/> <reminder duedate="15 seconds"/> <transition g="-76,-12" name="to Inspection" to="Inspection"/> </task> <mail-template name="task-notification"> <to addresses="xxx@xxx.be" /> <subject>Assignment notification</subject> <text>Task #{taskInstance.name} is assigned</text> </mail-template>
I assume that task-notification is a system template since i don't point to a specified template name (and regarding the manual).
This example works fine except for the context variables.
But i also tried the implementation you describe above i think the code you supplied above is from version 3
This is how my code look:<task duedate="10 seconds" g="36,108,97,52" name="Visa Conseiller"> <assignment-handler class="be.axi.bpm.handlers.TaskAssignmentHandler"/> <on event="task-assign"><mail template="mail-task-assign"></mail></on> <reminder duedate="15 seconds"/> <transition g="-76,-12" name="to Inspection" to="Inspection"/> </task> <mail-template name="mail-task-assign"> <to addresses="xxx@xxx.be" /> <subject>Assignment notification (E-C)</subject> <text>Task assigned</text> </mail-template>
But this code does noting at all (even not an Error msg). Is this event still supported in jBPM 4?

Gert -

12. Re: [jBPM 4] Mai templates context variables
tejjbpm Jul 27, 2009 2:53 PM (in response to gleenders)event type "task-notification" should work. In jbpm 4 "task-assign" is replaced with "task-notification" template.

13. Re: [jBPM 4] Mai templates context variables
kukeltje Jul 27, 2009 3:10 PM (in response to gleenders)I'm not 100% sure a mail element can be nested in a 'on' element in 4. But why not use the notify element with a template attribute?

14. Re: [jBPM 4] Mai templates context variables
gleenders Jul 28, 2009 3:27 AM (in response to gleenders)Now we're back where we started :-) .... those silly loops....
My initial try was this<task duedate="10 seconds" g="36,108,97,52" name="Visa Conseiller"> <assignment-handler class="be.axi.bpm.handlers.TaskAssignmentHandler"/> <notification/> <reminder duedate="15 seconds"/> <transition g="-76,-12" name="to Inspection" to="Inspection"/> </task> <mail-template name="task-notification"> <to addresses="xxxx@xxxi.be" /> <subject>Assignment notification (E)</subject> <text>Task assigned</text> </mail-template>
And this works fine except for the context variables, so my question rests the same....
