Subject Re: What is <entity-one> ?
Date Mon, 07 Jan 2013 06:44:04 GMT
Thanks for the help Atul. The concept is clear to me now.

So I just wanted to test that out. Instead of setting primary key value
from parameters, I thought of giving a hard coded value as follows.

<set field="dataResourceId" from-field="STDWRAP001"/>
<entity-one entity-name="DataResource" value-field="currentValue"/>
<set field="dataResource" from-field="currentValue"/>

where "STDWRAP001" is a valid dataresource id which exists in database. But
this is what I get in console.

*PrimaryKeyFinder.java:153:INFO ] Returning null because found incomplete
primary key in find: [GenericEntity:DataResource][dataResourceId,null()]*

What went wrong here?
