Jspx page visible property

Question

jdev 11.1.1.3
I need to show a command button in a row only if the value entered in "Price" input textbox is a positive value in that row of the table.
In the properties of the button, I added this
visible=#{row.bindings.Price.inputValue > 0}
I tested entering a -1 on the input textbox.
It gives me an error saying
Cannot convert -1 of type class oracle.jbo.domain.Number to class java.lang.Long
Help please!
Thanks

hi user,
It gives me an error sayingCannot convert -1 of type class oracle.jbo.domain.Number to class java.lang.Long
reason behind this error is:
your Price data type is will be Number.
but your comparing or doing like this visible=#{row.bindings.Price.inputValue *> 0*}
so two different type of data cant make compare itself.
so we have to cast.
as i consider your appraoch and i tried

}use this .it's working fine
