我需要PrimeFaces中的一個非常動態的視圖。視圖必須構建到運行時並添加PrimeFaces組件。帶動態添加組件的PrimeFaces視圖
在我的視圖中，我有一個panelgrid並添加了來自backing Bean的元素。我的問題是沒有setter被調用。我添加了一個ValueExpression，並且調用getter，但從來不是setter。

我支持bean
package com._9.controller.global;
import java.io.Serializable;
import java.text.ParseException;
import java.text.SimpleDateFormat;

@ManagedBean(name = "editor")
@ViewScoped
public class Editor implements Serializable
{
private static final long serialVersionUID = -33430593454354523L;
private String str_Text = "";
@PostConstruct
public void init()
{
}
public String getStr_Text()
{
return this.str_Text;
}
public void setStr_Text(String str_Text)
{
this.str_Text = str_Text;
}
public void setUiComponents()
{
org.primefaces.component.inputtext.InputText inpt_obj = new org.primefaces.component.inputtext.InputText();
inpt_obj.setValueExpression("value", createValueExpression("#{editor.str_text}", String.class));
HtmlPanelGroup tile = new HtmlPanelGroup();
tile.setId("testPanelGroup");
tile.getChildren().add(0, inpt_obj);
PanelGrid tiles;
tiles = (PanelGrid) FindComponent.doFind(FacesContext.getCurrentInstance(), "dynaForm:tiles");
tiles.getChildren().add(2, tile);
RequestContext.getCurrentInstance().update("dynaForm:tiles");
}
public ValueExpression createValueExpression(String valueExpression, Class<?> valueType)
{
FacesContext facesContext = FacesContext.getCurrentInstance();
return facesContext.getApplication().getExpressionFactory().createValueExpression(facesContext.getELContext(), valueExpression, valueType);
}
public void StoreDataVr()
{
int i = 0;
}
}
有沒有在我的setValueExpression導致二傳手到不行什麼問題？
