Unsetting tokens defined by other tokens

[cmzhu]

I have a dashboard where the token CgClassUserId is being populated from a dropdown, and then other tokens (like CgClass) are being evaluated subsequently. I want to set a token s_class to be true if CgClass == 'S' and unset it if not.

I am currently attempting this by having a change and condition match block of code after evaluating tokens like CgClass. However, with the addition of this code, when I change the CgClassUserId token, the subsequent eval tokens like CgClass are no longer changing as well.

   <input type="dropdown" token="CgClassUserId" searchWhenChanged="true">
          <label>Application</label>
          <fieldForLabel>Application</fieldForLabel>
          <fieldForValue>CgClassUserId</fieldForValue>
          <search>
            <query>| inputlookup ActivCgApplicationLookup.csv
    | eval CgClassUserId=CgClass.UserId
    | sort +Application</query>
            <earliest>0</earliest>
            <latest></latest>
          </search>
          <change>
            <!-- Use predefined input token $label$ to set Application token to selected label -->
            <set token="Application">$label$</set>
            <!-- Extract CgClass and UserId values from combined CgClassUserId for selected Application -->
            <eval token="CgClass">substr($CgClassUserId$,1,1)</eval>
            <eval token="CgClassClause">"host=\"*-".lower($CgClass$)."-*\""</eval>
            <eval token="UserId">substr($CgClassUserId$,2)</eval>
          </change>


          <change>
            <condition match="$CgClass$ != &quot;S&quot;">
              <unset token="s_class"></unset>
              <unset token="form.s_class"></unset>
            </condition>
            <condition match="$CgClass$ == &quot;S&quot;">
              <set token="s_class">true</set>
            </condition>
          </change> 
        </input>

The issue is you can only have one <change> block, so you have to consolidate everything.

<change>
  <condition match="substr($CgClassUserId$,1,1) != &quot;S&quot;">
    <set token="Application">$label$</set>
    <eval token="CgClass">substr($CgClassUserId$,1,1)</eval>
    <eval token="CgClassClause">"host=\"*-".lower($CgClass$)."-*\""</eval>
    <eval token="UserId">substr($CgClassUserId$,2)</eval>
    <unset token="form.s_class"></unset>
  </condition>
  <condition match="substr($CgClassUserId$,1,1) == &quot;S&quot;">
    <set token="Application">$label$</set>
    <eval token="CgClass">substr($CgClassUserId$,1,1)</eval>
    <eval token="CgClassClause">"host=\"*-".lower($CgClass$)."-*\""</eval>
    <eval token="UserId">substr($CgClassUserId$,2)</eval>
    <set token="form.s_class">true</set>
  </condition>
</change>
