[英]JSF / Primefaces composite component with nested composite component
我目前使用
並嘗試將復合組件放入復合組件中。
復合組件:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:composite="http://java.sun.com/jsf/composite" xmlns:p="http://primefaces.org/ui"
xmlns:components="http://java.sun.com/jsf/composite/components">
<composite:interface>
<composite:attribute name="myobject" required="true" />
</composite:interface>
<composite:implementation>
<p:panelGrid id="container">
<components:newEntry outputLabelId="labelId" outputLabelValue="#{msgs.label}"
selectOneMenuId="labelMenuId" selectOneMenuValue="#{myobject.value}"
selectOneMenuItems="#{myobject.values}" update=":targets">
</components:newEntry>
</p:panelGrid>
</composite:implementation>
</html>
嵌套的復合組件:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:composite="http://java.sun.com/jsf/composite" xmlns:p="http://primefaces.org/ui"
xmlns:components="http://java.sun.com/jsf/composite/components">
<composite:interface>
<composite:attribute name="outputLabelId" required="true" />
<composite:attribute name="outputLabelValue" required="true" />
<composite:attribute name="selectOneMenuId" required="true" />
<composite:attribute name="selectOneMenuValue" required="true" />
<composite:attribute name="selectOneMenuItems" required="true" />
<composite:attribute name="update" required="true" />
<composite:attribute name="rendered" default="true" />
</composite:interface>
<composite:implementation>
<p:row>
<p:column>
<p:outputLabel id="#{cc.attrs.outputLabelId}" value="#{cc.attrs.outputLabelValue}"
rendered="#{cc.attrs.rendered}" />
</p:column>
<p:column>
<p:selectOneMenu id="#{cc.attrs.selectOneMenuId}" value="#{cc.attrs.selectOneMenuValue}"
effect="none" filter="true" filterMatchMode="contains" rendered="#{cc.attrs.rendered}">
<f:selectItems value="#{cc.attrs.selectOneMenuItems}" />
<p:ajax event="change" update="#{cc.attrs.update}" />
</p:selectOneMenu>
</p:column>
</p:row>
</composite:implementation>
</html>
但是,我沒有收到錯誤消息或呈現的元素,這非常令人困惑。
僅當我將嵌套組件與其父組件移到同一級別時,才會渲染嵌套組件。
2.1.6是否不支持此功能,或者我做錯了什么?
我只是記得我以前在素面panelGrid上遇到過類似的問題。 panelGrid不知何故不接受嵌套的組件,只是吞下了它而沒有錯誤或警告。
用JSF替換素面panelGrid可解決此問題:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:composite="http://java.sun.com/jsf/composite" xmlns:p="http://primefaces.org/ui"
xmlns:components="http://java.sun.com/jsf/composite/components">
<composite:interface>
<composite:attribute name="myobject" required="true" />
</composite:interface>
<composite:implementation>
<h:panelGrid id="container">
<components:newEntry outputLabelId="labelId" outputLabelValue="#{msgs.label}"
selectOneMenuId="labelMenuId" selectOneMenuValue="#{myobject.value}"
selectOneMenuItems="#{myobject.values}" update=":targets">
</components:newEntry>
</h:panelGrid>
</composite:implementation>
</html>
由於具有JSF 2.3依賴性,我測試了Prime face 5.0。 在那個版本中,問題仍然存在。
