Hello,

I have a problem when I serialize my entity. I use the method writeXml (myEntity.writeXml). This methode give me a file xml but I can't deserialize this file. When I use the method (myFile.readXml), I obtain an xmlException. In fact, the structure of this xml file is bad. When I open this file with an wml editor, I detect of the errors.

I find several return to the line which causes a incoherence at the time of the interpretation.

Thank you for your Help.

Could you please be more specific? -> what's the build of the runtime libraries you're using (both serialization and deserialzation). Right click the ormsupportclasses dll, select properties -> version tab. (in explorer)

The error is about the time specification is wrong?

Version DLL : 1.0.20051.51112

If you want, I can send you my xml file. (By Email for example???)

In fact when I serialize my entity with a method WriteXml, I obtain a file xml containing errors (return to the line in full medium of tag xml) Thus I remove all these return to the line, in order to have an interpretable file xml.

But when I deserialize my file with the method readXml, i obtain a new exception :

contains errors ==>
SystemNullReferenceException : {"Object reference not set to an instance of an object."}

Could you try to use the latest runtime libraries (available in the customer area -> runtime libraries section). Your version is rather old, we've had a couple of bugfixes in the Xml code.

Ok I will test with the last version

Thanks
