Subject [jira] Commented: (COCOON-1725) Unexpected attempt to read values of JavaBean while saving form
Date Mon, 26 Dec 2005 21:17:32 GMT
    [ http://issues.apache.org/jira/browse/COCOON-1725?page=comments#action_12361240 ] 

Mark Lundquist commented on COCOON-1725:
----------------------------------------

But it's not just for debugging... the current and previous values are compared to decide
whether a model update is required.  So you would have to come up with some other way to make
that determination... either that, or say that @direction="save" entails unconditional updates.
 I don't know enough to say whether that would be feasible...?

> 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.
