I have no experience with ProcessMaker, but here's a couple of things you can try to investigate your issue:
- inspect the network traffic between ProcessMaker and Alfresco (e.g. with Wireshark) to see if there's any hint available in the HTTP responses from Alfresco
- enable DEBUG logs on Alfresco side
- as far as I can see, ProcessMaker users Alfresco CMIS REST APIs to implement its triggers. Have a look at
class.pmAlfrescoFunctions.php
in ProcessMaker and try the calls yourself with some REST client (e.g. curl, Chrome REST console, htty)
This should give you an idea of what's going wrong in your case.
UPDATE
After reading that the Japanese language pack changed a folder name from "Sites" to "/サイト", and double checking the Alfresco triggers code
, it's indeed the case that localized versions of Alfresco are not supported OOTB by ProcessMaker, which hardcodes "Sites" in its CMIS queries.
While the workaround provided by @nmenego would be enough in most cases, I opened a bug to ProcessMaker to let them know of the limitation.
