Getting error arrayindexoutofbound : 0 in extended VO

Question

Hi,
I have extended view object ApInvPoShipmentsVO(added new columns), initially I was getting error 'each row in the query result columns must be mapped to a unique query attribute in the mapped entity columns'  somehow I was able to resolve it.
But now while running the page I am getting Arrayindex.. 0 when trying to use/print a particular view attribute.
Also other custom added columns are fetching bad values, whereas when I run the same in sql dev. it is fetching correct value
I am badly stuck with this, any help will be very great full.
Regards

For this.. Please create transient attributes first(say column1,cloumn2 etc). Then modify your sql query to add your columns with names as exactly the same transient attribute name and then modify the transient attribute by checking the 'mapped to sql' check box.
looks like the attribute mapping is distorted. Try the above step and check.
