While this is working

when
        item : ItemVo(itemStatusCode == ItemVo.STATUS_INACTIVE) or
ItemVo(itemStatusCode == ItemVo.STATUS_DELETE)

Is this the right way of doing it ?

thanks

when

ItemVo.STATUS_DELETE )
when
        item : ItemVo ( itemStatusCode == ItemVo.STATUS_ACTIVE ||
itemStatusCode == ItemVo.STATUS_DELETE )
when
        item : ItemVo ( (itemStatusCode == ItemVo.STATUS_ACTIVE ||
itemStatusCode == ItemVo.STATUS_DELETE) )

ItemVo.STATUS_DELETE )
when
        item : ItemVo ( ( itemStatusCode == ItemVo.STATUS_ACTIVE ) || (
itemStatusCode == ItemVo.STATUS_DELETE ) )
when
        item : ItemVo ( itemStatusCode == ItemVo.STATUS_ACTIVE OR
itemStatusCode == ItemVo.STATUS_DELETE )

All of these when conditions fail for me ... Can somebody send the syntax
for two attributes check with OR condition ..

thanks

Thanks Rahul
Yes i was setting it in working memory thats why it was working in RHS
.....

workingMemory.setGlobal("itemValidationDao", itemValidationDao);
and then in the DRL
global com.walmart.itemfile.item.dao.ItemValidationDao
itemValidationDao;

I think i am missing something very basic ..

thanks

Did you set the global in the WorkingMemory?

You can do that using the API at

http://labs.jboss.com/file-access/default/members/jbossrules/freezone/do
cs/3.0.5/apidocs/index.html
and yes that is for 3.0.5. I am sure there is an
equivalent for the version that you are using.
