Serialization error

Hi all,

I am seeing a deserialization error. It only happens on certain servers, and I can't track down why. Wondering if anyone has any information.

I have a binary serialized version of a BooleanQuery. I then do:

BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream(Query);
Query deserializedQuery = (Query)bf.Deserialize(ms);

The last line fails with
Unknown parameter value: SHOULD
   at Lucene.Net.Util.Parameter.ReadResolve() in C:\Lucene.NET\C#\src\Lucene.Net\Util\Parameter.cs:line 70
   at System.Runtime.Serialization.ObjectManager.ResolveObjectReference(ObjectHolder holder)
   at System.Runtime.Serialization.ObjectManager.DoFixups()
   at System.Runtime.Serialization.Formatters.Binary.ObjectReader.Deserialize(HeaderHandler handler, __BinaryParser serParser, Boolean fCheck, Boolean isCrossAppDomain, IMethodCallMessage methodCallMessage)
   at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(Stream serializationStream, HeaderHandler handler, Boolean fCheck, Boolean isCrossAppDomain, IMethodCallMessage methodCallMessage)
   at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(Stream serializationStream)


Does anyone know what this could be? Like I said, it works on most of the computers here, but a couple of our web servers throw this.

Thanks,

I have had problems in Util.Parameter serialization with ReadResolve in
the past. Digy was kind enough to provide a patch in the past, if I
remember rightly. 

See https://issues.apache.org/jira/browse/LUCENENET-338

And https://issues.apache.org/jira/browse/LUCENENET-170

I wonder if it is the same issue?

Hi Ben,
Can you send a simple test case?

That's what I thought too, but it fails when the "client" and "server" are
the same process, which seems to indicate that it's not a version mismatch.

Thanks!

It looks like a version mismatch. i.e. these specific machines
are running a different Lucene.NET version.

Alternatively, if people have suggestions about how to send Queries through WCF I'd be interested in hearing about it.
