Hi All,

I have a Table A having the following schema: a-id, a-name

public class A{
int id; //get&set methods
String name; //get&set methods
}

and Table B having the following schema: b-id, a-id {a-id is a foreign-key referring Table A}

public class B{
int id; //get&set methods(Foreign Key)
int idB; //get&set methods

}

I have a SQL statement that create a Model List for being used on the webpage:


select * from A left join B on A.a-id = B.a-id;
  • which generates a-id, name, b-id

(aka C)

I created a grid using model as what (C) looks like. And there are 2 columns in the Grid namely:

B-ID,   Name ( aka D)

I would like to create a combobox for column (D) to update a record in Table B; the combobox should looks like:

Label of a-name but use the value with <a-id>

May I ask how to achieve it; is there any relevant small talks / previous thread that I can refer to?

Thanks a lot.

Didn't get your question very clearly, is it relates to UI or just your domain logic? maybe you should provide a simple one that relate to UI. and you can do the domain logic in the controller

Yes, you can set both label and value to a comboitem and then you can use Combobox.getSelectedItem().getValue() to replace Combobox.getValue()

sample:

<zk>
    <combobox id="cbx">
        <comboitem label="label one" value="value one" />
        <comboitem label="label two" value="value two" />
    </combobox>
    <button label="test">
        <attribute name="onClick"><![CDATA[
            if (cbx.getSelectedItem() != null) {
                System.out.println(cbx.getSelectedItem().getValue());
            } else {
                System.out.println("");
            }
        ]]></attribute>
    </button>
</zk>
