I need to have inputTexts inside
datatable when form is in editable mode. Everything works properly except form cleaning with immediate="true" (without form validation). Then primefaces
datatable behaves unpredictable. After filling in
datatable with new data - it still stores old values.
Short example:
test.xhtml
<h:body>
<h:form id="form">
<p:dataTable var="v" value="#{test.list}" id="testTable">
<p:column headerText="Test value">
<p:inputText value="#{v}"/>
</p:column>
</p:dataTable>
<h:dataTable var="v" value="#{test.list}" id="testTable1">
<h:column>
<f:facet name="header">
<h:outputText value="Test value" />
</f:facet>
<p:inputText value="#{v}" />
</h:column>
</h:dataTable>
<p:dataTable var="v" value="#{test.list}" id="testTable2">
<p:column headerText="Test value">
<h:outputText value="#{v}" />
</p:column>
</p:dataTable>
<p:commandButton value="Clear" actionListener="#{test.clear()}" immediate="true" update=":form:testTable :form:testTable1 :form:testTable2"/>
<p:commandButton value="Update" actionListener="#{test.update()}" update=":form:testTable :form:testTable1 :form:testTable2"/>
</h:form>
</h:body>
And java:
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.faces.bean.ViewScoped;
import javax.inject.Inject;
import javax.inject.Named;
@Named
@ViewScoped
public class Test implements Serializable {
private static final long serialVersionUID = 1L;
private List<String> list;
@PostConstruct
private void init(){
update();
}
public List<String> getList() {
return list;
}
public void setList(List<String> list) {
this.list = list;
}
public void clear() {
list = new ArrayList<String>();
}
public void update() {
list = new ArrayList<String>();
list.add("Item 1");
list.add("Item 2");
}
}
In the example above I have 3 configurations:
1. p:dataTable with p:inputText
2. h:dataTable with p:inputText
3. p:dataTable with h:outputText
And 2 buttons: first clears data, second applies data
Workflow:
1. Try to change data in inputTexts in p:dataTable and h:dataTable
2. Clear data of list (arrayList of string) - click "clear" button (imagine that you click cancel on form because you don't want to store data to database)
3. Load new data - click "update" button (imagine that you are openning new form with new data)
Question:
Why p:dataTable with p:inputText still stores manually changed data, not the loaded ones?
Is there any way to force p:dataTable to behaving like h:dataTable in this case?
