I have list of check boxes inside rich:dataTable and I want to check all the boxes at once with a single check box from header column.
<rich:column id="includeInWHMapping" >
<f:facet name="header">
<h:selectBooleanCheckbox value="#{checkallbox.selectAll}">
<f:ajax actionListener="#{checkallbox.selectAllBox}" render="selectedForWHProcess" />
</h:selectBooleanCheckbox>
</f:facet>
<h:selectBooleanCheckbox id="selectedForWHProcess" value="#{checkallbox.checked[data]}">
<f:ajax actionListener="#{checkallbox.selectAllRows}"/>
</h:selectBooleanCheckbox></rich:column>
Code in checkallbox Bean:
private Map<StandardStructure, Boolean> checked = new HashMap<StandardStructure, Boolean>();
private boolean selectAll;
public boolean isSelectAll() {
return selectAll;
}
public void setSelectAll(boolean selectAll) {
this.selectAll = selectAll;
}
public Map<StandardStructure, Boolean> getChecked() {
return checked;
}
public void setChecked(Map<StandardStructure, Boolean> checked) {
this.checked = checked;
}
public void selectAllBox(ValueChangeEvent e){
boolean newSelectAll = (Boolean) e.getNewValue();
Iterator<StandardStructure> keys = checked.keySet().iterator();
while(keys.hasNext()){
StandardStructure ss = keys.next();
checked.put(ss, newSelectAll);
}
}
When I check the h:selectBooleanCheckBox of header column nothing happens. What am I missing here? Should I have to implement Map for "selectAll" property too?
Thanks.
First of all. f:ajax
doesn't have actionListener
, it has a listener
. Read the docs here. Second thing, you can use valueChangeListener
on h:selectBooleanCheckbox
and only there. Third, listener inside rows boxes is wrong. Basically, it looks like you need to read this topic.
Now, here is the working example:
<h:form>
<rich:dataTable value="#{checkallbox.allValues}" var="data" id="dataTable">
<rich:column>
<f:facet name="header">
<h:selectBooleanCheckbox value="#{checkallbox.selectAll}"
valueChangeListener="#{checkallbox.selectAllBox}">
<f:ajax render="dataTable" />
</h:selectBooleanCheckbox>
</f:facet>
<h:selectBooleanCheckbox value="#{checkallbox.checked[data]}">
<f:ajax />
</h:selectBooleanCheckbox>
</rich:column>
<!-- other columns -->
</rich:dataTable>
</h:form>
Other possible problems with your code (since you've shared just a part).
equals
method is good. In 95% of case the default is not, especially if they are @Entity
.You have to make sure that the map is populated with false at the beginning. I use @PostConstruct
:
@PostConstruct
protected void performPostConstructAction() {
for (StandardStructure s : getAllValues()) {
checked.put(s, false);
}
}
