Nicolas Bouillon created TAP5-2475:
--------------------------------------
Summary: Form Field in Loop : on validation error all field get
the same value
Key: TAP5-2475
URL: https://issues.apache.org/jira/browse/TAP5-2475
Project: Tapestry 5
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.4
Reporter: Nicolas Bouillon
Priority: Blocker
On 5.4-beta-26.
Given a template like this :
{code:xml}
<t:form t:id="form">
<t:errors/>
<t:loop source="items" value="item">
<div>
<t:label for="field"/>
<t:textfield t:id="field" value="value" label="prop:item"/>
</div>
</t:loop>
<div>
<t:submit/>
</div>
</t:form>
{code}
If the validation of the form fails (global validation), the page is displayed
with all the field containing the same value, the last one.
{code:title=Index.java|borderStyle=solid}
public class Index {
private Map<String, String> values;
@Property
private String item;
public String[] getItems() {
return new String[]{"one", "two", "three"};
}
public void setValue(String value) {
if (values == null) {
values = new LinkedHashMap<>();
}
values.put(item, value);
}
public String getValue() {
if (values == null) {
values = new LinkedHashMap<>();
for (String item : getItems()) {
values.put(item, item);
}
}
return values.get(item);
}
@Inject
private AlertManager alertManager;
@InjectComponent
private Form form;
public void onValidateFromForm() {
form.recordError("Purposely generated error");
}
public void onSuccessFromForm() {
for (Map.Entry<String, String> entry : values.entrySet()) {
alertManager.info(entry.getKey() + " = " + entry.getValue());
}
}
}
{code}
Any help will be welcomed to guide me to provide a patch.
