Cannot edit properties after overwriting file in a document library

Question

I am (programmatically) overwriting a file in a document library after which none of the metadata fields can be edited either programmatically or manually:
Edit Properties -> change something -> Save
There is no error, just none of the metadata fields will actually update. To overwrite the file, I am using copy.asmx webservice. I get the same result when overwriting via REST, or just doing a plain http PUT. I also tried list.asmx webservice to update metadata.
As long as I don't overwrite a file, everything works great.
This is Sharepoint 2010. Versioning is off, checkout is not required. "Overwriting" means there is an existing file, previously uploaded manually or with copyservice and the new file has the same name.
Has anybody seen this behavior? (or managed to get a sharepoint document library file into a similar state).
Thanks, RL

Hi,
According to your post, my understanding is that after uploading file using the Copy.asmx web service, you could not edit the properties.
I had used the following code to upload the file, after that to edit the properties, it worked without any issue.
static void Main(string[] args)
Copy copy = new Copy();
copy.Credentials = new System.Net.NetworkCredential("UserName","Password","Domain");
copy.Url = "http://sp/_vti_bin/copy.asmx";
string filePath = @"C:\Test\Edite2.txt";
string[] destURL = { @"http://sp/LIbA/Edite2.txt" };
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read);
byte[] contents = new byte [fs.Length];
fs.Read(contents,0,Convert.ToInt32(fs.Length));
fs.Close();
FieldInformation fileFieldInfo = new FieldInformation();
fileFieldInfo.DisplayName = "Edite2";
fileFieldInfo.Value = "Edite2";
fileFieldInfo.InternalName = "Edite2";
fileFieldInfo.Type = sp.FieldType.Text;
FieldInformation[] fileFieldInfoArray = { fileFieldInfo };
CopyResult copyResult1 = new CopyResult();
CopyResult copyResult2 = new CopyResult();
CopyResult[] copyResultArray = { copyResult1,copyResult2};
uint resultCopy = copy.CopyIntoItems(filePath,destURL,fileFieldInfoArray,contents,out copyResultArray);
Console.WriteLine("Upload Successful...");
Console.ReadKey();
You can check with the above code, then check whether it works.
Did the issue occur in other libraries?
You can create new library to check whether it works, maybe the library had been corrupted.
