Conditional Workflow Activity

Question

Hello,
We have created our own "change user password" workflow to include two new activities. One is to unlock the users other resources on a password change and the second is notify the user that they have changed their password.
     <Activity id='2' name='Reprovision'>
        <Comments>
          Since passwords have all been stored in the WSUser
          object, all we have to do here is reprovision.
        </Comments>
        <Action id='0' process='Provision'>
          <Argument name='op' value='reProvision'/>
        </Action>
        <Transition to='UnlockAD'/>
      </Activity>
      <Activity id='3' name='UnlockAD'>
        <Comments>
          On Success do a global unlock .
        </Comments>
        <Action id='0' application='com.waveset.session.WorkflowServices'>
          <Argument name='op' value='checkoutView'/>
          <Argument name='type' value='Unlock'/>
          <Argument name='id' value='$(accountId)'/>
          <Argument name='subject' value='<ADMINUSER>'/>
          <Argument name='authorized' value='true'/>
          <Return from='view' to='myview'/>
        </Action>
        <Action id='1'>
          <expression>
            <block>
              <set>
                <ref>myview.global.accountLocked</ref>
                <s>false</s>
              </set>
            </block>
          </expression>
        </Action>
        <Action id='2' application='com.waveset.session.WorkflowServices'>
          <Argument name='op' value='checkinView'/>
          <Argument name='subject' value='<ADMINUSER>'/>
          <Argument name='authorized' value='true'/>
          <Argument name='view' value='$(myview)'/>
        </Action>
        <Transition to='Notify User'/>
      </Activity>
      <Activity id='4' name='Notify User' audit='true'>
        <Variable name='user'/>
        <Variable name='toAddress'/>
        <Action id='0' application='com.waveset.session.WorkflowServices'>
          <Argument name='op' value='getView'/>
          <Argument name='type' value='User'/>
          <Argument name='id' value='$(accountId)'/>
          <Argument name='subject' value='<ADMINUSER>'/>
          <Argument name='noFetch' value='false'/>
          <Argument name='TargetResources'>
            <list>
              <s>Lighthouse</s>
            </list>
          </Argument>
          <Return from='view' to='user'/>
        </Action>
        <Action id='1' process='Notify'>
          <Argument name='notificationRetryCount' value='$(notificationRetryCount)'/>
          <Argument name='notificationRetryWait' value='$(notificationRetryWait)'/>
          <Argument name='notificationRetryResult' value='$(notificationRetryResult)'/>
          <Argument name='notificationException' value='$(notificationException)'/>
          <Argument name='template' value='PasswordSyncNotification'/>
          <Argument name='toAddress'>
            <ref>user.waveset.email</ref>
          </Argument>
        </Action>
        <Transition to='end'/>
      </Activity>
      <Activity id='5' name='end'>
      </Activity>The problem is that if the user does not have any other resource accounts (such as AD) we receive the following " Operational error"
"The following error occurred:com.waveset.util.WavesetException:User has no resource accounts that support the Unlock feature."
Question:
How would I go about making <Activity id='3' name='UnlockAD'> only execute if the user has an AD account or an account on a resource that supports the Unlock feature?

Answer 1

Two ways:
1) You can add a <Condition> tag under your <Action> tag. That is basically a true / false filter to the action.
Something like:
             <Activity name="Next">
                <Action>
                    <Condition>
                        <eq>
                            <ref>accountblah</ref>
                            <s>Some String</s>
                        </eq>
                    </Condition>
                    ... rest of your action code
                </Action>
                <Transition to="Other"/>
            </Activity>2) You can control flow into your activities using the transition element:
<Transition to="Unlock">
    <eq>
        <ref>myflag</ref>
        <s>something</s>
    <eq>
</Transition>
<Transition to="DoNotUnlock"/>Edited by: MichaelF on Jul 16, 2009 9:00 AM
