Hello guys, hello John, With my team, I am using the wonderful Ruote engine (recently upgraded to 2.3.0) in a production environment, with an average of 20 new processes created every day.
I recently fixed a bug in a workflow that caused some workitems to move into an error condition. I had the following information about the error: message: #<NoMethodError: undefined method `size' for nil:NilClass> trace: /home/rails/apps/arts/shared/bundle/ruby/1.8/gems/ruote-2.2.0/lib/ ruote/exp/fe_concurrence.rb:286:in `merge_all_workitems' .../ruby/1.8/gems/ruote-2.2.0/lib/ruote/exp/fe_concurrence.rb:258:in `reply_to_parent' .../ruby/1.8/gems/ruote-2.2.0/lib/ruote/exp/flowexpression.rb:228:in `do_apply' .../ruby/1.8/gems/ruote-2.2.0/lib/ruote/worker.rb:326:in `launch' .../ruby/1.8/gems/ruote-2.2.0/lib/ruote/worker.rb:243:in `process' .../ruby/1.8/gems/ruote-2.2.0/lib/ruote/worker.rb:173:in `step' .../ruby/1.8/gems/ruote-2.2.0/lib/ruote/worker.rb:75:in `run' ./script/ruote_worker:23 ./script/service:107:in `instance_eval' ./script/service:107:in `boot!' ./script/service:38:in `initialize' ./script/ruote_worker:12:in `new' ./script/ruote_worker:12 The mistake was the use of a :unless clause in a :concurrence expression, as highlighted by the following unit test: https://gist.github.com/beaefdcc70a718c42ed5 Nesting the :concurrence expression into a :sequence expression and moving the :unless clause up into the :sequence resolved the problem (but there were other ways, such as an :if expression). Probably the issue is documented, but I could not find it. However, my current problem is with the errors that such situation raised. >From my business point of view, I resolved with restarting a new process for any process in error state. Therefore the processes in error state had to be removed from the engine. I tried to kill those processes with @engine.kill_process(error.wfid) but that seems to have no effect. Am i making any mistake? Can someone suggest me a way to remove definitely the processes?
