Assembly is not marked as serializable

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run .netTiers templates against SQL server 2005 database with the
IncludeWCFDataAttributes = True.
2. Run the admin website.
3. trying to display the EntityName.aspx page results in the error

 Type 'SomeNamespace.Web.Data.ProviderDataSourceDeepLoadList' in Assembly
'SomeNamespace.Web, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'
is not marked as serializable.

What is the expected output? What do you see instead?
I expected to see the datarows for my entity table

What version of .netTiers and CodeSmith are you using?
v2.3.0.b2 Codesmith 5.0

Please provide any additional information below.

Fix is to set IncludeWCFDataAttributes = False and regenerate the code.

The actual fix is to modify the EntityInstanceBase.generated.cst file by 
changing 
the following:

<% if ( IncludeWCFDataAttributes ) { %>
    [DataContract]
    <% } else { %>
    [Serializable]
    <% } %>

to

<% if ( IncludeWCFDataAttributes ) { %>
    [DataContract, Serializable]
    <% } else { %>
    [Serializable]
    <% } %>

How does one get access to make coding modifications, I can implement this 
change.

Serializable attribute was applied like you show above until Rev 757.  The fix 
you
propose seems appropriate.  Would like to confirm that this was an unintended 
side
effect.

This issue is related to Rev 757

Also needs to make the similar change in EntityData template.  After that the 
sample
app seems to be working without issue.  Generated using Northwind.

I had an application that tested this.  Making this change worries me a little. 

Please fully test entity serialization in order to see if this works.  You 
shouldn't 
have to mark things serializable when using WCF.

Is the Admin Website running through the Web Services maybe.  You shouldn't be 
able 
to use the WebServices with the DataContract attributes.

I don't know, the DataContract attributes were in bad shape when I fixed them.  
I 
will see if I still have all my tests I ran when I coded this.

I see now that the DataContract should be an acceptable substitute for the
serializable attribute.  Maybe the issue is with the way the admin site is 
setup. I'm
working on getting a sample running that uses the web services project...

What is the status of this bug?

Original comment by bniemyjski on 25 May 2009 at 4:20

• Changed state: Accepted

Although the DataContract attribute is appropriate for WCF it is not 
appropriate 
when serializing elsewhere.  Serialization is done directly when making a deep 
copy 
of the object, specifically in the EntityHelper Clone<T> method.  The classes 
mentioned should be marked as serializable for the DeepCopy to work.  This 
creates 
an issue anywhere deepcopy is used.

As far as I can tell the suggested changes resolve the issue.

On the latest version of code that is downloadable from main google code page, 
this
error still exists.

Revision 821 does not include this patch and the exception 
Type 'SomeNamespace.Web.Data.ProviderDataSourceDeepLoadList' in Assembly
'SomeNamespace.Web, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'
is not marked as serializable.

still occurs in the website admin pages as described above when selecting 
IncludeWCFDataAttributes.

The current featured download still has this issue when 
IncludeWCFDataAttributes is set to true.
