Difference between generating VO while creating EO and otherwise

Question

Hello All,
I wanted to know - Is there any difference between
creating a VO while creating an EO (i.e.by checking 'Generate Default View Object')
and
when If I create an EO first , then seperately create a VO for the same table used in EO; and then attach that EO to the VO . By attaching EO to VO, I mean, after creation of VO ; if we right click that VO to edit - the 'View Object Editor ' window opens. here, I select an EO through the 'Select Entity Objects for this View Object' window.
My requirement was to create a page where I wanted to do search and create. In the create page, the employee id and date has to come automatically. When submit button is clicked, the record is to be saved .
1st I tried through the second method. I got the search results and in the create page, the id&date came as expected but create wasnt successfull. No error or exception came but in the record that got inserted into database had only the id,date and who column values. The other columns had null value.
Later, when I tried using the 2nd method i.e by using the 'Default VO generated', creation was successfull.
Could anybody tell me why it wasnt working the second way?

There is no difference between creating a VO while creating an EO (i.e.by checking 'Generate Default View Object') and create an EO first , and then seperately creating VO . The latter is used if u haven't planned to make which VO or haven't finalised VO query.
In ur case it looks the first time some mapping in VO might have not created correctly in any one case!
