Out of the box i dont think you will be able to start it based on the language of the page. There is an extra tab in edit mode where you can manually start a workflow.
Do you have specific editors for every language or is it the same editors for several languages? If so an editor could be given the rights to manually start a workflow say SequentialApprovalEnglish where that WF would call a group EnglishApprovers. That would however give manual work which the user might forget.
I will check with a colleague if its possible to trigger based on language out of the box but i doubt it, would probably need some custom code to achieve it and then it depends if you have specific editors for every language or not how much work it would be.
Have checked this and as assumed its not possible out of the box to have automatic triggers based on the language so you will need to develop this on your own.
Another way is as I mentioned above to manually start the workflow and if the client got different editors per language you should be able to have them start different types of workflows (only allow them to start based on their language) like for example SequentialApprovalEnglish and SequentialApprovalSwedish to update different approvers about it.
Good luck with the project
The behaviour of the Sequential approval workflow that ship with EPiServer is exactly what I'm looking for. When an editor saves a page an approver will automatically get a notification to approve the page. The only problem is that I want to use different approvers for different language branches. Is this possible to accomplish or do I have to create a custom Workflow?
Thanks in advance
