Using Form Fragments

[Robson Pires]

Hi,

I'm currently working on a component which use a loop to render a list of
fields dynamically. Following this is the structure of the component:

componentA.tml

<t:container
  xmlns:t="http://tapestry.apache.org/schema/tapestry_5_4.xsd";
  xmlns:p="tapestry:parameter">
  <div style="height: 500px; overflow: scroll; overflow-x: hidden">

    <t:loop t:source="properties" value="property" encoder="encoder" >
      <t:if test="case">

        <t:delegate to="case" />

        <!-- TEXT -->
        <t:block t:id="text">
          <t:formfragment visible="printable">
            <div class="form-group">
              <t:label for="textField" class="col-sm-4 control-label" />
              <div class="col-sm-8">
                <input t:type="TextField" t:id="textField"
                  value="property.second.defaultValue.rawValue"
                  label="${label}" />
              </div>
            </div>
          </t:formfragment>
        </t:block>
    </t:loop>

  </div>
</t:container>

ComponentA.java

public class ComponentAextends  {


  @Parameter(name = "properties", required = true)
  @Property
  protected List<ObjectPair<ObjectA, ObjectB>>> properties;

  @Property
  private ObjectPair<ObjectA, ObjectB> property;

@Property
  private final ValueEncoder<ObjectPair<ObjectA, ObjectB>> encoder =
 new ValueEncoder<ObjectPair<ObjectA, ObjectB>>() {
    public String toClient(
        ObjectPair<ObjectA, ObjectB> namedKeyObject) {

      String clientValue = "-1";

      if (namedKeyObject != null) {
        clientValue = String.valueOf(namedKeyObject.getFirst().getKey());
      }
      return clientValue;

    }

    public ObjectPair<ObjectA,ObjectB> toValue(
        String key) {

      if (!Misc.isEmptyString(key) && !"-1".equals(key)) {
        long filterKey = Long.valueOf(key).longValue();

        for (int i = 0; i < properties.size(); i++) {

          if (properties.get(i).getFirst().getKey() == filterKey) {
            return properties.get(i);
          }
        }
      }

      return null;
    }
  };

...

My problem is when I click in the button to send the values only the last
field is coming filled, the other fields are coming null. I thought could
be a problem with my encoder but I have seen that the encoder is working
fine. Someone has any idea about this?


Thank you,
