--------------------------------
Resolution: Fixed
> 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: 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.
