Thread: Failure to save changes in Kupu.
Failure to save changes in Kupu.

I've seen this problem periodically.

There seem to be two issues occurring:

1. A change is actually saved on the server but Kupu has
silently stripped
out the changes made, so it appears that no change has been
saved.
2. There is a failure on the server to save the new file
version. 

In regards to the first issue we have, through modification
of the relevant
kupu files, achieved a solution that works.

I'm now trying to solve the second problem. I'm using Lenya
1.2.5 on Windows
XP with Tomcat 5.0. This problem has been reported
previously but without a
satisfactory resolution it seems, possibly because of its
intermittent
nature.

I've found that the editDocument() routine in
webappslenyalenyausecasesedit_document.js is giving an
exception on
trying to save modifications to a file a second time
around.

Note: I had to change the logging call to get a relevant
error message in
the cocoon log-file as below;

     //cocoon.log.error("Can not edit document.",
exception);
        cocoon.log.error("Can not edit document: "
 + exception.toString());

The error message I am seeing is as below:

ERROR flow.invoke0():?  - Can not edit document:
JavaException:
java.io.IOException: Could not rename
C:tomcatwebappslenyalenyapubstlpcontentauthoringind
exindex_en.xml.tmp
to
C:tomcatwebappslenyalenyapubstlpcontentauthoringind
exindex_en.xml

This is being caused by the call below;

        SourceUtil.copy(resolver,
cocoon.parameters["sourceUri"], dstUri,
_getParameter("useBuffer", "false") ==
"true");

which is to the static method in
org.apache.lenya.cms.cocoon.source.SourceUtil.

There is no actual index_en.xml.tmp file being left behind.

I'm wondering if anyone has any suggestions. It does seem to
me like a file
access issue.

Thanks

Steve Cameron

Further details on this error, but not solved as yet.

I've investigated the possibility of getting a stack trace
for the error.
Firstly, I modified the file SourceUtil.java as follows:

    public static void copy(SourceResolver resolver, String
sourceUri,
String destUri, boolean useBuffer) 
    throws IOException, SourceException {
        Source source = null;
        Source dest = null;
        try {
            source = resolver.resolveURI(sourceUri);
            dest = resolver.resolveURI(destUri);
            
            if(!(dest instanceof ModifiableSource))
                throw new SourceException("Destination
'"+ dest.getURI() +
"' is not modifiable.");
            
            copy(source, (ModifiableSource) dest,
useBuffer);     
        }
//***added following catch
        catch(Exception e){    
           throw new SourceException(stack2string(e));      
            
        }
        finally {
            if(source != null)
                resolver.release(source);
            if(dest != null)
                resolver.release(dest);
        }
    }

//***added following method to convert stack trace to a
string. 
public static String stack2string(Exception e) {
  try {
    StringWriter sw = new StringWriter();
    PrintWriter pw = new PrintWriter(sw);
    e.printStackTrace(pw);
    return "------rn" + sw.toString() +
"------rn";
  }
  catch(Exception e2) {
    return "bad stack2string";
  }
}	

This gave the following information in the cocoon log-file:

However, this information is generated after a _successful_
save in Kupu. I
presume it means that the xhtml returned by Kupu is not
valid but is being
saved and then successfully used by Lenya as the new page
version.

So far, I've not been able to trap an unsuccessful save.
