Hi all,

At the end I solved it using the same method to select categories: a multiValueSelector and ajaxFileSelector to browse spaces and select files. ajaxFileSelector allows specify the mimetype of files to select. I want to specify the type of files too, so I created UIAjaxFileAssocPicker and AjaxFileAssocSelectorTag class to add a new param to specify the type of files of the selector. Now, the problem is the new param is always null. This is my implementation:

UIAjaxFileAssocPicker class:


public class UIAjaxFileAssocPicker extends BaseAjaxItemPicker
{
   /** list of mimetypes to restrict the available file list */
   private String mimetypes = null;
   private String type = null;
   
   @Override
   public String getFamily()
   {
      return "org.alfresco.faces.AjaxFileAssocPicker";
   }
   
      /**
    * @see javax.faces.component.StateHolder#restoreState(javax.faces.context.FacesContext, java.lang.Object)
    */
   public void restoreState(FacesContext context, Object state)
   {
      Object values[] = (Object[])state;
      super.restoreState(context, values[0]);
      this.mimetypes = (String)values[1];
      this.type = (String)values[2];
   }
   
   /**
    * @see javax.faces.component.StateHolder#saveState(javax.faces.context.FacesContext)
    */
   public Object saveState(FacesContext context)
   {
      Object values[] = new Object[] {
         super.saveState(context),
         this.mimetypes,
         this.type};
      return values;
   }

   @Override
   protected String getServiceCall()
   {
      return "EditContentPropertiesDialog.getFileFolderNodes";
   }

   @Override
   protected String getDefaultIcon()
   {
      // none required - we always return an icon name in the service call
      return null;
   }
   
   @Override
   protected String getRequestAttributes()
   {
      String mimetypes = getMimetypes();
      String type = getType();
      String string = null;
      if (mimetypes != null)
      {
         string = "mimetypes=" + URLEncoder.encode(mimetypes);
      }
      if (type != null)
      {
         if(string != null && string.length() > 0){
            string += " types=" + URLEncoder.encode(type);
         }else{
            string = " types=" + URLEncoder.encode(type);
         }
      }
      return string;
   }
   
   
   // ——————————————————————————
   // Strongly typed component property accessors
   
   /**
    * @return Returns the mimetypes to restrict the file list.
    */
   public String getMimetypes()
   {
      ValueBinding vb = getValueBinding("mimetypes");
      if (vb != null)
      {
         this.mimetypes = (String)vb.getValue(getFacesContext());
      }
      
      return this.mimetypes;
   }
   
   /**
    * @param mimetypes The mimetypes restriction list to set.
    */
   public void setMimetypes(String mimetypes)
   {
      this.mimetypes = mimetypes;
   }
   
   public String getType()
   {
      ValueBinding vb = getValueBinding("type");
      if (vb != null)
      {
         this.type = (String)vb.getValue(getFacesContext());
      }
      
      return this.type;
   }
   
   public void setType(String type)
   {
      this.type = type;
   }
}

I have add in edit-content-properties.jsp

            </f:subview>
      </r:multiValueSelector>
   </h:panelGrid>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The selector works fine and show like I want but the type param of ajaxFileAssocSelector tag is always null. I specify that it´s type="{InvoiceModel.model}invoice" but when I retrive it in EditContentPropertiesDialog.getFileFolderNodes(), it´s always null. Can somebody point me what is the problem? Is implementation right?

EditContentPropertiesDialog.getFileFolderNodes():


…
         Set<String> types = null;
         String typeParam = (String)params.get("type");
         System.out.println("typeParam " + typeParam); //always is null!!!!
         if (typeParam != null && typeParam.length() != 0)
         {
            // convert to a set of types to test each file against
            types = new HashSet<String>();
            for (StringTokenizer t = new StringTokenizer(typeParam, ","); t.hasMoreTokens(); /**/)
            {
               types.add(t.nextToken());
            }
         }
…

Hi all,

I found the problem. It´s in getRequestAttributes() method of UIAjaxFileAssocPicker class. I have to return a string with the params: mimetypes and type but I don´t know how the string has to be. Mimetypes param can have several values separate by comma, so the real type param value is got like a value of mimetypes param and type param value is set null. Can somebody point me what getRequestAttributes() method should return?

Thanks a lot in advance,
