Yes we use ajax to change to portlet mode if you use the default UI of GateIn

- To run your JS after an change portlet mode by ajax: there are several ways:

         - Use the standard portlet extra markup header --> add <script> element to the html header

         - Put the <script> in your portlet template

         - others: use GateIn api: org.exoplatform.web.application.JavascriptManager --> this class help to add script to the page

- To switch portlet mode that refresh the page, you need to build portlet url that help to change the portlet mode (pls look at the portlet api spec) then use the GateIn extension machanism (you can find examples in GateIn source code), override UIPortlet.gtmpl template --> replace GateIn default "change portlet mode" URL by yours

- So the first issue: run portlet JS after ajax updated is resolved , right ? Now you want to use jQuery provide by GateIn. Yes, build-in jQuery of GateIn comes in JS module format, if you want to use it, your script need to be AMD too. Here is the document https://docs.jboss.org/author/display/GTNPORTAL36/JavaScript+in+GateIn

- maven dependency for JavascriptManager class:

  <dependency>

    <groupId>org.gatein.portal</groupId>

    <artifactId>exo.portal.component.web.resources</artifactId>

  </dependency>

the repository is here

sorry for the late answer, about JavascriptManager, you can use this:

     JavascriptManager jsMan = WebuiRequestContext.<WebuiRequestContext>getCurrentInstance().getJavascriptManager();

      jsMan.addCustomizedOnLoadScript(...);

you will need this maven dependency:

     <dependency>

       <groupId>org.gatein.portal</groupId>

       <artifactId>exo.portal.webui.framework</artifactId>

     </dependency>

GateIn JS loading support is very flexible, you can still call for both scripts, and modules when rendering portlet. Let say we have scripts and modules defined in gatein-resources.xml

     <scripts>

          <name>foo</name>

           ....

     </scripts>

     <module>

          <name>bar</name>

          ....

     </module>

When the portlet is renderred:

  public void render(RenderRequest req, RenderResponse resp) throws PortletException, IOException {

    resp.setProperty("org.gatein.javascript.dependency", "SHARED/foo");

    resp.addProperty("org.gatein.javascript.dependency", "SHARED/bar");

  }

That way no need to depends on GateIn specific dependencies.
