Hi,
I have a selectOneListbox with serveral Items. When selecting an item in this box I want a inputText field to be updated with a correspondant value. To achieve this I use a valueChangeListener on the selectOneListbox to update the Values in the backing bean and a a4j:support to reRender the inputText field. Any ideas why this doesn't work?
<h:form id="viewControllerForm" enctype="multipart/form-data">
<h:selectOneListbox id="SelectData" size="5" valueChangeListener="#{viewController.selectionChanged}">
<f:selectItems value="#{viewController.getDataToSelect()}" />
<a4j:support event="onchange" reRender="InputFields"/>
</h:selectOneListbox>
<h:panelGrid id="InputFields" columns="2">
<h:inputText id="input_value_1" value="#{viewController.value1}" />
<h:inputText id="input_value_2" value="#{viewController.value2}" />
</h:panelGrid>
</h:form>There is more code inside the form but I left it for reading purposes.
private String value1;
private String value2;
@Out(required = false)
public String getValue1() {
return value1;
}
@In(required = false, create = true)
public void setValue1(String value1) {
this.value1= value1;
}
@Out(required = false)
public String getValue2() {
return value2;
}
@In(required = false, create = true)
public void setValue2(String value2) {
this.value2= value2;
}
public void selectionChanged(ValueChangeEvent e) {
if (e.getNewValue() instanceof String) {
String item = (String) e.getNewValue();
if (item != null) {
value1 = item.split(",")[0];
value2 = item.split(",")[1];
}
}
}
Something else is strange: The selectionChangedListener is only called if the <a4j:support event="onchange" /> tag is added. As far as I know it should work without, too.
Thx, for your help.
Chris
