Hello everyone!

Why is it that methods MobileFormatter.SerializeObject and MobileFormatter.GetObject are scoped as internal rather than public? Wouldn't I need to call these methods from OnGetChildren and OnSetChildren when using backing fields for my child objects?

Thanks for the help!

OnGet/OnSetChildrent should contain formatter as one of the parameters.  You should be able to use is.  Here is what I have (see below).  Does this work for you?

 

private string _someField;

 

    protected override void OnGetChildren(Csla.Serialization.Mobile.SerializationInfo info, Csla.Serialization.Mobile.MobileFormatter formatter)

    {

      var fieldManagerInfo = formatter.SerializeObject(_someField);

      info.AddChild("_someField", fieldManagerInfo.ReferenceId);

    }

Hi Sergey,

I am but only for new types. The many existing ones I am leaving as is (except for adding the serialization code and public constructors). This system is old and currently has a win forms UI. Now however there are some new sub systems we're creating in Silverlight. These new sub systems use types from the old sub systems.

Thanks

Hmm…  The code I pasted into my email does compile on my machine (in CSLA Light and CSLA projects), and I only have a references to CSLA DLLs there.  Did you try to download the latest source for Csla Light to see if that works better for you?  I looked at the source again, and these methods in MobileFormatter are public.

Hi Sergey,

Thanks for the response first and foremost.

I believe I have the latest version of the CSLA code base. And in that code base the SerializeObject method is scoped as internal so I can't call it from the outside. By now I've gotten around the issue by changing against my will the access modifier for this method and GetObject to public. I say against my will because I do my best to avoid changing the framework code so that upgrading does not become problematic. Do you know if this will be changed?????

Thanks

 

I see…  My bad.  I am actually working on it straight in source code, in 3.6 version.  So, essentially I am running against today’s version of source code…  I am sure you will see the fix in the next code drop, but I am not sure when.  Can you run SVN browser to see if you can see current branch?  If so, you can download the latest source code?

Hi Sergey,

I downloaded the code again and still I see these methods scoped as internal. Where are you downloading your code from? I am getting mine from http://www.lhotka.net/cslalight/download.aspx

Thanks

Thanks.  Those issues have been fixed already – I just looked in source.

Hi Sergey,

Thanks for the info. I will try that and if I can't I will wait for the next version.

One other thing I want to mention to you. One other area I am having problems is with methods ReadOnlyBase.OnGetChildren and ReadOnlyBase.OnSetChildren. In cases whereby the _fieldManager field is null, such as when the read only object only uses backing fields, these methods bomb with null ref exception. I had mentioned to Rocky on his blog that this was happening but I believe he only made changes to BusinessBase because there I see the code checking to make sure _fieldManager is not null before attempting to serialize. It would be great if the same checks can be added to ReadOnlyBase.

Thanks very much for all your help! I really do appreciate it
