Subject: [jira] Commented: (COCOON-1689) Cannot save a cform containing a
multivalued field with more than 9 values !

Sylvain Wallez commented on COCOON-1689:
----------------------------------------
We have no indication of the JXPath problem that led to avoiding the use of
jxpathContext.removePath(). Giacomo, as the author of this change, can you give
us more indications on what motivated it ?
This was a workaround due to a bug in JXPath removePath() method
reported by Jeremy and me prior to ApacheCon in Stuttgart. At that time
it was fixed in their repository but not released (and we do not want to
have unreleased jars in our repository). I'll check whether it works
with current jxpath jar.
Cannot save a cform containing a multivalued field with more than 9 values !

Key: COCOON-1689
URL: http://issues.apache.org/jira/browse/COCOON-1689
Project: Cocoon
Type: Bug
Components: Blocks: Forms
Versions: 2.1.8, 2.1.9-dev (current SVN), 2.2-dev (Current SVN)
Reporter: Philippe Gassmann
Priority: Minor
An UnsupportedOperationException occurs when trying to save a form containing a
multivalued field with more that 9 values. Here is the explanation :
here is the incriminated code in MultiValueJXPathBinding.java:doSave():
Iterator rowPointers = multiValueContext.iteratePointers(this.rowPath);
List l = new ArrayList();
while( rowPointers.hasNext() )
{
Pointer p = (Pointer)rowPointers.next();
l.add(p.asPath());
}
Collections.sort(l);
for( int i = l.size()-1; i >= 0; i-- )
{
multiValueContext.removePath((String)l.get(i));
}
This code is wrong :
The p.asPath returns something like "/doc/node[x]"
if the iterator contains more than 9 values x will be written in TWO characters
so, the result of Collections.sort(l) return for 10 values :
/doc/node[10]
/doc/node[1]
/doc/node[2]
/doc/node[3]
/doc/node[4]
/doc/node[5]
/doc/node[6]
/doc/node[7]
/doc/node[8]
/doc/node[9]
so the first node to be deleted is 9. the last is 10. but when trying to delete
the 10th node it does not exist anymore !
A UnsupportedOperationException is thrown.
