Here from 52nd line where process method has been called, throws this error.
I have used a component where I have also used allowDML="true", but still it throws error.
Please help me.
Yes it is working from page action method.

You cannot have a DML statement run in your constructor.
Thank you very much. I didn't know it.
So in this case, should I call Approval.process method from page.action?
