Thank you for the reply. Your are right. One of my challenges is to enable users to pick the attributes to dynamically display what they want, just like the 'New Query' function in 'Search Object' in AwareIM Standard menu. However, I did not find AwareIM to provide templet/widzard to implement it.
Another big challenge is to display the a parent with multiple children structure (i.e, a view with sub-view of child BO). I'd like to build query on parent BO to display part of parent's attributes with all Child BO's attributes in a sub-table. Is there any way to display the result without using self-defined presentation?
