    <description>&lt;P&gt;I have resolved the problem. The error was because the task belonged to old instance workflow and it not launch correct operation.&lt;/P&gt;</description>

      <title>Why this error occurs in automation chain when use @ChainParameters?</title>
      <link>https://connect.hyland.com/t5/nuxeo-forum/why-this-error-occurs-in-automation-chain-when-use/m-p/328307#M15308</link>
      <description>&lt;P&gt;Hello,&lt;/P&gt;
&lt;P&gt;I am building a "automation chain" operations (&lt;STRONG&gt;WF_anadirPermisoSolicitud&lt;/STRONG&gt;) that it has one parameter. This operation is referenced by other chain with a "Run Chain" operation (&lt;STRONG&gt;WF_anadirListaPermisosSolicitud&lt;/STRONG&gt;), using the parameters field.&lt;/P&gt;
&lt;P&gt;The definition for both chains:
&lt;STRONG&gt;WF_anadirListaPermisosSolicitud&lt;/STRONG&gt;&lt;/P&gt;
&lt;PRE&gt;&lt;CODE&gt;- Context.RunOperation:
    id: WF_anadirPermisoSolicitud
    isolate: "false"
    parameters:
      testName: valueParameterTest
&lt;/CODE&gt;&lt;/PRE&gt;
&lt;P&gt;&lt;STRONG&gt;WF_anadirPermisoSolicitud&lt;/STRONG&gt;&lt;/P&gt;
&lt;PRE&gt;&lt;CODE&gt;params:
  - testName:
      type: string
operations:
  - Context.FetchDocument
  - Seam.AddInfoMessage:
      message: "@{ChainParameters['testName']}"
&lt;/CODE&gt;&lt;/PRE&gt;
&lt;P&gt;&lt;STRONG&gt;The chain operation is executed from transition´s buttons of workflow task&lt;/STRONG&gt;. I have attached the error printed LOG, when &lt;STRONG&gt;WF_anadirListaPermisosSolicitud&lt;/STRONG&gt; is executed.
Is supported the "@{ChainParameters['parameterName']}" in Nuxeo 6.0?? I think that it´s not.&lt;/P&gt;
&lt;P&gt;Thanks, Regards&lt;/P&gt;</description>
