display Freemarker in JSP in explorer?

[esource]

I wanted to use Freemarker in JSPs in explorer.  How would I do this?  How would I create a dialog for example?

[esource]

Yes, it helps very much. Thank you!  Thank you for your posts!

Now, the question I have is how can I pass a list of Nodes,  a java.util.List of Nodes to my freemarker template and have it display the list as well as information from the list? 

I assume I would have to put this List in the model. 

I tried:

   model.put("nodeList", this.browseBean.getContent());
‍‍‍

But this returns an error from Alfresco :

16:51:45,208 User:admin ERROR [ui.common.Utils] 05040003 Error during processing
of the template 'null'. Please contact your system administrator.
org.alfresco.service.cmr.repository.TemplateException: 05040003 Error during pro

i do not know that this is possible, because space is made for this reason .

Can you tell how would you get this list of nodes?

[esource]

I perform a search in Alfresco from which I receive a search result list.  I then modified browse.jsp, adding a button

<td style="padding-right:4px" align=right>
      <%– custom button  –%>
      <nobr><a:actionLink value="CustomButton" image="/custom/images/icons/customButton.png" style="white-space:nowrap" actionListener="#{CustomDialog.myMethod}" id="mylink1" /></nobr>
</td> 
‍‍‍‍‍‍

Clicking this button opens CustomDialog calling myMethod:

public class CustomDialog extends BaseDialogBean {

     Map<String, Object> templateModel;       
   protected TemplateImageResolver imageResolver;

   public void myMethod(ActionEvent event) {
      imageResolver = new TemplateImageResolver() {
            public String resolveImagePathForName(String filename,
               FileTypeImageSize size) {

                FacesContext context = FacesContext.getCurrentInstance();
                ServletContext servletContext = ((HttpServletRequest) context
                   .getExternalContext().getRequest()).getSession()
                   .getServletContext();
                return FileTypeImageUtils.getFileTypeImage(servletContext,
                   filename, size);
            }

      };

      // go to custom dialog
                FacesContext fc = FacesContext.getCurrentInstance();
      fc.getApplication().getNavigationHandler().handleNavigation(fc, null, "dialog:custom");
      
         }

     public Map getTemplateModel()
     {
           Map<String, Object> model = new HashMap<String, Object>(4, 1.0f);
           
                     model.put("nodeList", this.browseBean.getContent());
           model.put(TemplateService.KEY_IMAGE_RESOLVER, imageResolver);
           
           return model;
     }

   @Override
   protected String finishImpl(FacesContext context, String outcome) throws Exception {
      // return the default outcome
      return outcome;
   }
   
   public TemplateImageResolver getImageResolver() {
      return imageResolver;
   }

   public void setImageResolver(TemplateImageResolver imageResolver) {
      this.imageResolver = imageResolver;
   }

   public void setTemplateModel(Map<String, Object> templateModel) {
      this.templateModel = templateModel;
   }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

this attempts to open a dialog, but an error results from the call to

model.put("nodeList", this.browseBean.getContent());

web-client-config-custom.xml

         <dialog name="custom" page="/jsp/extension/dialogs/custom.jsp" managed-bean="CustomDialog"
                    icon="/custom/images/icons/custom_1.gif" title="Custom" 
                    description="Displays custom list" />
‍‍‍‍‍

faces-config-custom.xml

   <managed-bean>
      <managed-bean-name>CustomDialog</managed-bean-name>
      <managed-bean-class>co.esource.web.bean.CustomDialog</managed-bean-class>
      <managed-bean-scope>session</managed-bean-scope>
        <managed-property>
         <property-name>nodeService</property-name>
         <value>#{NodeService}</value>
       </managed-property>
       <managed-property>
         <property-name>browseBean</property-name>
         <value>#{BrowseBean}</value>
       </managed-property>

custom.jsp

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="/WEB-INF/repo.tld" prefix="r" %>

<r:template template="alfresco/templates/custom.ftl" model="#{CustomDialog.templateModel}" /> 
‍‍‍‍‍‍‍

[esource]

If I remove the call to :

model.put("nodeList", this.browseBean.getContent());
‍‍‍

no error occurs.  And in fact I can pass values from CustomDialog to the freemarker template via the model as an example:

model.put("hello","hello, how are you");
‍‍‍

And I also have access to the node results from the search, but the values have to be transcribed, copied into my own custom node as example:

     public Map getTemplateModel()
     {
          nameList = new java.util.ArrayList<String>();        
          customList = new java.util.ArrayList<customNode>();      
          List<Node> searchResults = this.browseBean.getContent();  
          Integer searchResultsCount = searchResults.size();
         for(ListIterator<Node>li=searchResults.listIterator(); li.hasNext(); ) 
         {
               Node resultNode = li.next();
               String Name = resultNode.getName();
                         nameList.add(Name);
                         customList.add(new customNode(resultNode));
          }

           Map<String, Object> model = new HashMap<String, Object>(4, 1.0f);
           model.put("names", nameList);
           model.put("custom", customList);
                     //model.put("nodeList", this.browseBean.getContent());
           model.put(TemplateService.KEY_IMAGE_RESOLVER, imageResolver);
           
           return model;
     }

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

[esource]

So, I can get search results to display in freemarker but I cannot send the nodes directly.  It seems the nodes have to be copied into custom objects.

[savic_prvoslav]

you can perform a search into freemarker with

childrenByLuceneSearch
Returns a map capable of executing a search against the entire repository based on a Lucene search string. It returns a sequence of nodes which represent the objects from the results of the search, such as companyhome.childrenByLuceneSearch["TEXT:alfresco* AND TEXT:tutorial*"]. The value can be any valid Lucene search string supported by Alfresco. Note that you may need to escape Lucene specific characters. Note that the entire repository is searched: the current node is only used as an access point to retrieve the search object.

http://wiki.alfresco.com/wiki/Template_Guide you have this hire.
