What is <entity-one> ?

[Winster]

Hi,

Can anyone please help me to understand below xml?

Please correct me if I am wrong. "dataResourceId" is taken from parameters
and set to field "dataResourceId". And DataResource entity is fetched (but
which will act as primary key here?) and set to field "currentValue" and
later "currentValue" is assigned to another field "dataResource".

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

Whatever are the primary keys of the entity DataResource, will be searched  
in the "context".

Why primary keys? because you are using entity-ONE.

And the context is where you are setting variables, dataResourceId in line  
1, currentValue in line 2 and dataResource in line 3.

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?

Oops.. that was a mistake. I should not have used from-field.
"default-value" worked for me.

Thanks anyway.

You can simply use following pattern :

<entity-one entity-name="DataResource" value-field="currentValue">
            <field-map field-name="dataResourceId" value="STDWRAP001"/>
</entity-one>


Thanks & Regards

Jose,

Please take some time to understand the Mini-language grammar:

https://cwiki.apache.org/OFBADMIN/mini-language-reference.html

The statement

<set field="dataResourceId" from-field="STDWRAP001"/>


is saying "set the contents of the dataResourceId variable to the value
contained in the STDWRAP001 variable." I don't think that is what you
want. I think you want this:

<set field="dataResourceId" value="STDWRAP001"/>


which says "set the contents of the dataResourceId variable to the
constant 'STDWRAP001'."

-Adrian
