jsf datatable validation

[vivek ja]

I have a datatable which contains rows of textboxes. I want to validate each of these input fields.
I get a nullpointer exception on UIComponent.findComponent.
This is how I access the value
uiComponent.findComponent("selectForm:invoice:0:amount")
uiComponent.findComponent("selectForm:invoice:0:name")
etc.,

where each row corresponds to an Invoice bean that has getters and setters

I am not sure if this is the right way to access the field.

I submitted the above before completing the message. Sorry!
I am not sure how to access indexed fields
Can someone please help me out with this?
