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, 2.2-dev (Current SVN), 2.1.9-dev (current SVN)
Reporter: Philippe Gassmann
Priority: Blocker
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.
