Hi,

have you tried to give another var-value to see if there is a naming conflict. The word attriute is very often used on our business.

Leo

[dhanarajar]

ya I tried that also by giving different var name etc........
but not working.....

and it is working for some condition (previous time also) and getting this error only in some situation only.....

cant guess wthr it is a jsp problem or it is an java class problem.........

this is my drop down retrieve method---------->>>>>>>

public List<IcFacilityAmenityAttributes> updateAttributes(IcBusiness selectedInstance){

return em.createQuery("from IcFacilityAmenityAttributes icAttributes where 1=1 and icAttributes.icInstance = :instance")

.setParameter("instance", selectedInstance.getIcInstance())
.getResultList();
     }


-------------------------------------------------------------

<h:selectOneMenu id="AttributeId" value="#{allocateBookables.attributes}" style="font-size: 10px; color: #880000; width: 100px;float:left;" >

I declared "allocateBookables.attributes" in my action class like this--------->>>


private IcFacilityAmenityAttributes attributes;
     public IcFacilityAmenityAttributes getAttributes() {
          return attributes;
     }

     public void setAttributes(IcFacilityAmenityAttributes attributes) {
          this.attributes = attributes;
     }

-----------------------------------------------------------------

Hi,

and it is working for some condition (previous time also) and getting this error only in some situation only.....

So you say it works sometimes, but not always? Are you sure the query returns something ?

Leo

[dhanarajar]

ya its because  my query problem only ............

Now i solved that problem.....

now everything is working fine for me...................

THANK YOU VERY MUCH FOR YOUR GUIDANCE !!!!!!!!!!!!!

Hi,

although it saves a lot of keystrokes, optmizing (shortening) code makes testing difficult.

Try something like:

public List<IcFacilityAmenityAttributes> updateAttributes(IcBusiness selectedInstance){

List<IcFacilityAmenityAttributes> result;

Query q = em.createQuery("from IcFacilityAmenityAttributes icAttributes where 1=1 and icAttributes.icInstance = :instance");
log.debug(<<LOG SOMETHING TO CHECK>>);
q.setParameter("instance", selectedInstance.getIcInstance())
result = q.getResultList();
log.debug(<<LOG SOMETHING TO CHECK>>);

return result;

 }

As soon as it works correctly you can optimize, (remove the logs and make it shorter), but there is really no need to do that.
