Hi.
I have tried this namedQuery:
Code:
<query name="Plate.findPlatesByExperiment">
<![CDATA[select p from Plate p where p.experiment = ? ]]>
</query>
but when I try it I get a IllegalArgumentException on my plate id. I haven't been able to figure this out at all. Some googling have brought me to these two pages:
http://www.developpez.net/forums/archive/index.php/t-145907.htmlhttp://forum.hibernate.org/viewtopic.php?t=964102But since neither my french nor my german is very good I think we need a post of this problem in english as well.
What does the:
ERROR BasicPropertyAccessor:167 - IllegalArgumentException in class: net.bioclipse.lis.pojos.AbstractBaseObject, getter method of property: id
mean? I mean I wrote that class and I didn't put any IllegalArgumentException throwing there...
