Hi,

I'm newbie in tapestry, i have a problem when i want to show a foreign field
value in textfield. it show me the error as below:
Parameter(s) 'translate' are required for
org.apache.tapestry5.corelib.components.TextField, but have not been bound.

in java is:
================================
@Component(id = "Customer")
private Customer customer;
public Customer getCustomer()
{
   return customer;
}
public void setCustomer(Customer customer)
{
   this.customer = customer;
}
===============================
in tml is:
===============================
<input  t:type="TextField" t:id="Customer" t:value="Customer"
t:maxLenght="5" t:size="5" />
===============================

may i know how to solve this kind of problem?
*Remark: Customer field is a foreign field.

Thank you.

Regards,
Tan
