(but it seems impossible because , a subprocess can get only one collection)</SPAN><BR /><BR /><SPAN>Thanks in advance</SPAN></BODY></HTML> Mon, 02 Jun 2014 09:44:32 GMT fabrice1 2014-06-02T09:44:32Z Why does it risk to update a variable during a process ? https://connect.hyland.com/t5/alfresco-archive/why-does-it-risk-to-update-a-variable-during-a-process/m-p/179124#M132254 Hello,I'm looking to update a variable and I found this topichttp://forums.activiti.org/content/how-update-process-variableMr Barrey told this "Why would you want that?
