Lifecycle for class object (PhysicalDevice)

[Valentin]

Hello.
I am trying to add a lifecycle for an object. Using instructions from the website. I fixed the typos and the "state attribute" declaration. But the controls lifecycle don't show up.
Maybe you need to declare buttons?
Use iTop 3.0.0

  <class id="PhysicalDevice" _delta="if_exists">
    <properties>
      <fields_semantic>
        <state_attribute>status</state_attribute>
      </fields_semantic>
    </properties>

    <fields>
      <field id="status">
      <default_value _delta="redefine">implementation</default_value>
      </field>
    </fields>

      <lifecycle _delta="define">
        <!-- list of possible stimuli, triggering transition -->
        <stimuli>
          <stimulus id="ev_move2prod" xsi:type="StimulusUserAction"/>
          <stimulus id="ev_obsolete" xsi:type="StimulusUserAction"/>
          <stimulus id="ev_stock" xsi:type="StimulusUserAction"/>
        </stimuli>
        <states>
          <state id="implementation">
            <flags/>
            <!-- From each state, define possible transitions -->
            <transitions>
              <!-- Recommended: use stimulus code as transition id -->
              <transition id="ev_move2prod">
                <!-- Define the stimulus which will trigger that transition -->
                <stimulus>ev_move2prod</stimulus>
                <!-- define the target state, where the transition will end -->
                <target>production</target>
                <!-- below flags are mandatory but can be empty -->
                <flags/>
                <actions/>
              </transition>
            </transitions>
          </state>
          <state id="production">
            <flags/>
            <transitions>
              <transition id="ev_obsolete">
                <target>obsolete</target>
                <actions/>
              </transition>
              <transition id="ev_stock">
                <target>stock</target>
                <actions/>
              </transition>
            </transitions>
          </state>
          <state id="obsolete">
            <flags/>
            <transitions/>
          </state>
          <state id="stock">
            <flags/>
            <transitions>
              <!-- The below transition is identical to the one on state implementation -->
              <transition id="ev_move2prod">
                <stimulus>ev_move2prod</stimulus>
                <target>production</target>
                <flags/>
                <actions/>
              </transition>
            </transitions>
          </state>
        </states>
      </lifecycle>
  </class>

Might be overlooking it, but aren't you missing a specification where you say which the initial state is?

[Valentin]

<default_value _delta="redefine">implementation</default_value>
specifies a default value for "status".

[Jeffrey Bostoen]

Sorry, in the documentation I noticed "initial_state_path", although it doesn't seem to be present in datamodel-production.xml ? Is this something deprecated, it seems present in the code though?

[Valentin]

In the documentation says "initial_state_path", but it's optional.
I think the documentation is incomplete. It looks like you need to write a php class for the target object type

[Valentin]

Seems to have figured it out.
The physical device is an abstract class.
I thought (based on the example on the site) that the lifecycle is inherited by subordinate classes. Looks like no.
I defined a lifecycle for a real object and it worked.

Hello,
Thanks for the feedback Valentin !
We might need to update the wiki : I've just checked the XML reference and indeed there's a lack of details on this subject :/ What do you think @cisou ?
