Problem with new status added on UserRequest class

[Fotios Kossyvas]

I have the following error shown by iTop toolkit:

Class UserRequest

Unknown function '' in transition [assigned/ev_progress] for state attribute 'status' (Specify a function which prototype is in the form [public function (...){return true;}])
Unknown function '' in transition [progress/ev_pending] for state attribute 'status' (Specify a function which prototype is in the form [public function (...){return true;}])
Unknown function '' in transition [progress/ev_resolve] for state attribute 'status' (Specify a function which prototype is in the form [public function (...){return true;}])
Unknown function '' in transition [progress/ev_autoresolve] for state attribute 'status' (Specify a function which prototype is in the form [public function (...){return true;}])

I have edited the UserRequest by doing this :
1) added a new value (progress) for the enumerated field named status
2) added a new <stimulus id="user-content-ev_progress" xsi:type="StimulusUserAction">
3) added the following code to the <transitions> part of the state <state id="user-content-assigned"></state></transitions></stimulus>

              <transition id="ev_progress">
                <target>progress</target>
                <actions>
                  <action>
                    <verb>SetCurrentDate</verb>
                    <params>
                      <param xsi:type="attcode">progress_date</param>
                    </params>
                  </action>
                </actions>
              </transition>

4) Defined the progress state using the following code :

          <state id="progress">
            <inherit_flags_from>assigned</inherit_flags_from>
            <flags/>          
            <transitions>
              <transition id="ev_pending">
                <target>pending</target>
                <actions>
                  <action>
                    <verb>SetCurrentDate</verb>
                    <params>
                      <param xsi:type="attcode">last_pending_date</param>
                    </params>

                  </action>
                  <action>
                    <verb>SetElapsedTime</verb>
                    <params>
                      <param xsi:type="attcode">time_spent</param>
                      <param xsi:type="attcode">start_date</param>
                      <param xsi:type="string">DefaultWorkingTimeComputer</param>

              <transition id="ev_timeout">

              <transition id="ev_autoresolve">
                <target>resolved</target>
                <actions>

                      <param xsi:type="attcode">time_spent</param>
                      <param xsi:type="attcode">start_date</param>
                      <param xsi:type="string">DefaultWorkingTimeComputer</param>

                  <action>
                    <verb>ResolveChildTickets</verb>
                    <params/>
                  </action>
                </actions>
              </transition>
            </transitions>
          </state>

The progress_date field is a new field already defined in the Ticket class (parent of UserRequest)

I thought that i had defined everything but i have these errors above and when (of course) i am trying to change the status of a user request from assigned to progress (using the iTop UI) i get "The action has failed."

Can anyone tell me what i am missing here?
Thank you

[dlp]

can you give the complete datamodel? I will try to test it, and see what is wrong.

Thank you being so helpful dlp but finally i resolved my problem!
As always, trying to explain the problem to another person, many times drives you to the solution of the problem ;-)
The problem was some _delta="redefine" and _delta="define_if_not_exists" missing, like in

<stimulus id="ev_progress" xsi:type="StimulusUserAction" _delta="define_if_not_exists" />

and in

<state id="progress" _delta="define_if_not_exists">

and in

 <state id="assigned" _delta="redefine"> 

[dlp]

Great!
Yes the errors logs are not very clear when you put a wrong attribute to delta...
