set component page parameter dynamically

Question

Im setting a component in a custom page template like the following. This means that the nodeRef parameter will be set by url. Is it possible to set the nodeRef parameter by code dynamically?

thank you!

<sub-components>
    <sub-component id="default">
       <evaluations>
          <evaluation>
             <evaluators>
                <evaluator type="config.component.evaluator">
                   <params>
                      <element>DocumentDetails/document-details/display-web-preview</element>
                   </params>
                </evaluator>
             </evaluators>
             <url>/components/preview/web-preview</url>
             <properties>
                <nodeRef>{nodeRef}</nodeRef>
                <api>api</api>
                <proxy>alfresco</proxy>
                <dependencyGroup>document-details</dependencyGroup>
             </properties>
          </evaluation>
       </evaluations>
    </sub-component>

Sure. In your example the /components/preview/web-preview is pointing to a web script. The web script has a controller (web-preview.get.js) and in that controller it grabs the nodeRef param and does something with it.

If you want to use a different nodeRef, you can extend that web script and enhance the logic accordingly.

For example, I recently needed to change the nodeRef that the previewer displays. Instead of showing the current node's content I wanted to show a related node's content. So I extended web-preview.get.js and changed the Alfresco.WebPreview widget instantiation to use the nodeRef that I fetched from an association instead of the nodeRef that was passed in.
