hello,
I used the soap API 6.7 on the old version of cascadeServer.
To use the soap API 6.10 I have to understand how the EntityType attribute is now managed . It is completely removed and it makes my code wrong.

How can I find this attribute from the new class PublishableAsset?
If this is not possible is there a simple solution to implement it?

Thx,
Nicolas

   Can you please include a sample of your script that you're having issues with?

   This is a very short sample :

   List assets = ....
   for (PublishableAsset asset : assets) {
   if (asset.getEntityType().getName().equals(EntityTypeString.page)) {...

   And here, the methode getEntityType does not exist since the new version API 6.10.
   Is there a way to do this without getEntityType methdoe?

   Hi,

   Given that you are using Java, you should be able to replace your type checks with an "instanceof" check like the following:

   if (asset instanceof com.hannonhill.www.ws.ns.AssetOperationService.Page)
   

   Can you tell me where you're getting the list of PublishableAssets? Most API operations that return collections of assets of mixed-types specify the explicit type of the assets being returned. I'd be curious to see where you were getting a set of PublishableAssets from.

   Thanks!

   Hello Bradley,

   Use the instanceOf operator is great, thx.
   In fact I find the PublishableAssets from :

   List<PublishableAsset> assets;
   try {
        assets = cs1.listFolder(path);
   } catch (RemoteException e) {
        e.printStackTrace();
        return;
   }
   

   The listFolder methode is in the CascadeServer class, it's :

   public List<PublishableAsset> listFolder(String path) throws RemoteException {
   
           List<PublishableAsset> assets = new ArrayList<PublishableAsset>();
   
           // === Parse all the assets contained inside this folder :
           Folder f = handler.read( authentication, new Identifier(null, new Path(path, null, site),EntityTypeString.folder, false)).getAsset().getFolder();
   
           // Indicates a folder.
           Identifier[] ids = f.getChildren();
           for (int i = 0; i < ids.length; i++) {
   
               if (ids[i].getType().equals(EntityTypeString.page)) {
                   Asset a = handler.read( authentication, new Identifier(ids[i].getId(), null, ids[i].getType(), false)).getAsset();
                   assets.add(a.getPage());
               }
   
               if (ids[i].getType().equals(EntityTypeString.folder)) {
                   Asset a = handler.read(
                           authentication,
                           new Identifier(ids[i].getId(), null, ids[i].getType(),
                                   false)).getAsset();
                   assets.add(a.getFolder());
               }
   
           }
   
           return assets;
       }
   

   Is it not a good solution ???

   But now, with 6.10.9 version I want try my Java code on the example but there are lot of errors.
   On my listFolder method I have a new NullPointerException exception with the following code :

   List<PublishableAsset> assets = new ArrayList<PublishableAsset>();
           //Path
           Path pat = new Path(path, null, site);
          
           // === Parse all the assets contained inside this folder :
           Identifier iden = new Identifier(null, pat,EntityTypeString.folder, false);
          
           if (authentication == null){
               System.out.println("auth null");
           }
           if (iden == null){
               System.out.println("iden null");
           }
          
           //Folder f = handler.read( authentication, iden).getAsset().getFolder();
           Folder f = handler.read( authentication, iden).getAsset().getFolder();
   

   on my script I asked assets = cs1.listFolder("_compagny"); with the site : private String site = "example.com";

   Can you explain to me the raison of my bug ??

   Your code to read the contents of a Folder and create a collection of all the Folder's children looks fine.

   Your NullPointerException is likely happening around here:

           //Folder f = handler.read( authentication, iden).getAsset().getFolder();
           Folder f = handler.read( authentication, iden).getAsset().getFolder();
   

   You need to make sure that the getAsset is not null before trying to invoke getFolder on it. Can you include some actual values that you're using to build the Path object?
