Reg how to start a worklfow from js using rule?

dynamolalit — Fri, 26 Mar 2010 09:39:49 GMT

Hi,I have a space called 'Under Review' under my repository which is used as an intermediate place to put content while it is in workflow.If content is approved, it will go to same space from where it had been uploaded, if it is rejected, it will go to 'User Home' of user who is uploading the conten

Hi,

I am still stuck up. :?:

I tried with logging as a normal user & using following syntax to access 'Under Review' space for admin:

document.owner='admin';
companyhome.owner='admin';
space.owner='admin';
var targetFolder = companyhome.childByNamePath("/{http://www.alfresco.org/model/application/1.0}company_home/{http://www.alfresco.org/model/application/1.0}dictionary/{http://www.alfresco.org/model/content/1.0}Under Review");
//var targetFolder = companyhome.childByNamePath("Under Review");
logger.log("targetFolder !@@!"+targetFolder);
var res = document.move(targetFolder);

Here i am getting targetFolder as null :!:

14:10:14,599 User:xxxxx DEBUG [repo.jscript.ScriptLogger] targetFolder !@@!null

My idea here is to get companyhome node for admin as i have created 'Under Review' space inside Data Dictionary which only admin can see.

What i inferred from here is that each user has its own companyhome node. 8).Or may be for company home there are different views for each of user & normal user can not access spaces on which they do not have any rights. So getting companyhome for admin is an issue from a normal user perspective.

So its visibility thing that comes into picture.Normal user can not see the companyhome for admin.

So is there any workaround for this?

Any idea?

Hi,

It can be done as a combination of JavaScript+Java in Alfresco.I created a processdefinition.xml which invokes my Custom ActionHandler.

java script code executing as a rule :


//This worlfow is triggered as any content is uploaded in repository using DM.
logger.log('************* Starting Approval workflow! *************');
var workflow = actions.create("start-workflow"); 
workflow.parameters.workflowName = "jbpm$workflwo_name";
var APPROVER_GROUP="APPROVER_GROUP_NAME";
var approverGroup=people.getGroup("GROUP_"+APPROVER_GROUP);
workflow.parameters["bpm_groupAssignee"] = approverGroup;
workflow.parameters["bpm:workflowDescription"] = "This document is pending for your approval."; 
workflow.execute(document);

Along with this, I updated permissions for "Under Review" so that admin is coordinator for it & Approver is consumer for it.
