Unexpected attempt to read values of JavaBean while saving form
---------------------------------------------------------------

         Key: COCOON-1725
         URL: http://issues.apache.org/jira/browse/COCOON-1725
     Project: Cocoon
        Type: Bug
  Components: Blocks: Forms  
    Versions: 2.1.8    
    Reporter: g[R]eK
    Priority: Minor


Problem lays in org.apache.cocoon.forms.binding.ValueJXPathBinding.doSave at 
line 123:
        Object oldValue = jxpc.getValue(this.xpath); //line 123
        if (getLogger().isDebugEnabled()) {
            getLogger().debug("value= " + value + "-- oldvalue=" + oldValue);
        }

This is for debugging purpose and it's quite handy but if there is no get 
method in bean exception org.apache.commons.jxpath.JXPathException: No read 
method will be thrown and binding will be interrupted. It will try to read 
value even @direction="save" is set.

I think it is not valid to require read method while it is excplicitly stressed 
the direction of binding.
