Conditionally Display ADF Command Button

Question

I have an ADF table with a select option. I have a command button that executes a query titled "View Detail". I want the button to display but I only want it enabled when the Item Name column in the selected row of the table appears in a separate view object which takes the Item Name as a parameter.
Thank you for your help.

Thank you Frank,
Let me be more clear - I hope this is not too confusing.
I have an adf table (ID ItemsTable) that has the following columns:
Select, Object Name, Sequence, Item Name, Source
I set autosubmit on the Select column to true
I set the ID to Select
The partialtrigger value on the table is ItemsTable:Select
I have a command button in the table header labeled "View Details".
I have a view object (Obtotal) with the following syntax
select object_name from
objects
where object_name = :vitem;
In the page def, I created an action to execute the VO and pass #{row.ItemName} into the vitem bind variable. I also invoke the action.
The disabled property of my View Details button is
#{bindings.Obtotal.estimatedRowCount >=1}
The partialtrigger value is ItemsTable:Select
I would expect that each time I select a different row, the row.ItemName would be passed to the view object which would execute and return different results based on the vitem passed.
I would expect my View Details button to toggle (enabled/disabled) based on the whether or not there are results in the Obtotal iterator.
I must be missing something because My View Details button is always enabled.
Thank you for your help.
