Conversion error in write access to a property

Question

Hello,
in JSF I get a conversion error when I try to save an order.
An order object has a from- and a to-address.
To avoid duplicate coding I encapsulated the address data in a class Address.
public class Order implements Serializable{
  private Address fromAddress;
  private Address toAddress;
  //Getter/Setter for addresses are implemented
public class Address implements Serializable{
  private String city;
  private String country;
  private String remark;
  //Getter/Setter for all fields are implemented
}Reading the address data works without problems.
Writing (saving an order) does not work. For each property of Address a conversion error is thrown.
The access is like
<t:inputText value="#{orderBean.order.address.country}" .../>
Principally it is possible to access the address properties because reading works.
What is going wrong when writing?
And how could I find out more details about the conversion errors occurred?
Any hints appreciated

Hello,
I'm afraid these are the fileds causing the errors.
Here is an excerpt from the JSP.
When I set rendered="false" for the panelGroup containing five "crucial" fields, I get five messages "conversion error" less.
<t:panelTab label="#{messages['auftrag.reiter_von']}" rendered="true">
        <t:panelGrid columns="1">
          <%-- Line with input fields--%>
          <t:panelGroup>
            <t:panelGrid columns="5">
              <!-- Name -->
              <t:inputText size="20" maxlength="80"
                value="#{orderBean.order.fromAddress.name}"
                readonly="#{orderBean.readonly}">
              </t:inputText>
              <!-- Street -->
              <t:inputText size="20" maxlength="80"
                value="#{orderBean.order.fromAddress.street}"
                readonly="#{orderBean.readonly}">
              </t:inputText>
              <!-- Zip -->
              <t:inputText size="5" maxlength="10"
                value="#{orderBean.order.fromAddress.zip}"
                readonly="#{orderBean.readonly}">
              </t:inputText>
              <!-- Country -->
              <t:inputText size="5" maxlength="5"
                value="#{orderBean.order.fromAddress.country}"
                readonly="#{orderBean.readonly}">
              </t:inputText>
              <!-- City -->
              <t:inputText size="40" maxlength="80"
                value="#{orderBean.order.fromAddress.city}"
                readonly="#{orderBean.readonly}">
              </t:inputText>
            </t:panelGrid>
          </t:panelGroup>Thx for assistance. If there is no solution in sight, I will refactor it the way I described. It already took me too much time...
