मैं सिर्फ RichFaces 3 और 4PrimeFaces/JSF घटक आईडी पी के भीतर से नहीं मिला: datatable
से आ रही PrimeFaces 3.3.1 के साथ शुरू कर रहा हूँ मैं संरचना के साथ एक datatable है:
<f:facet name="header">
<h:outputText value="Employees" />
</f:facet>
<p:column sortBy="#{emp.lastName}">
<f:facet name="header">
<h:outputText value="Last Name" />
</f:facet>
<h:outputText value="#{emp.lastName}" />
</p:column>
<p:column>
<f:facet name="header">
<h:outputText value="First Name" />
</f:facet>
<h:outputText value="#{emp.firstName}" />
</p:column>
...
<p:column>
<p:commandButton icon="ui-icon ui-icon-trash"
value="Remove"
process="@this"
update="employee-remove-dialog"
oncomplete="employeeRemoveDialog.show();">
<f:setPropertyActionListener target="#{employeeManager.currentEmployee}" value="#{emp}" />
</p:commandButton>
</p:column>
</p:dataTable>
<p:dialog header="Remove Employee"
modal="true"
appendToBody="true"
widgetVar="employeeRemoveDialog"
id="employee-remove-dialog">
<h:outputText value="Remove employee #{employeeManager.currentEmployee.fullName}?" />
<f:facet name="footer">
<p:commandButton icon="ui-icon ui-icon-check"
value="OK"
action="#{employeeManager.deleteEmployee}"
process="@this"
update="employee-list"
oncomplete="employeeRemoveDialog.hide();" />
<p:commandButton icon="ui-icon ui-icon-close"
value="Cancel"
onclick="employeeRemoveDialog.hide();"
ajax="false"
immediate="true" />
</f:facet>
</p:dialog>
</h:form>

आईडी नहीं पाया जा सकता है:
हालांकि PrimeFaces एक अपवाद फेंकता है। हम्म .... मैंने मूल रूप से रिचफेस से संरचना की प्रतिलिपि बनाई। पंक्ति को हटाने या संपादित करने के लिए पंक्ति बटन की आवश्यकता नहीं है: कर्मचारी-फॉर्म: ... उपसर्ग। मुझे आश्चर्य है क्यों।
जब प्रपत्र एक आईडी दे रही है और साथ पीएफ घटक संदर्भ लगाकर ':' वाक्य रचना कोड चलाता है के रूप में उम्मीद:
<h:form id="employee-form">
<p:dataTable ...>
...
<p:column>
<h:panelGrid ...>
<p:commandButton ...
update=":employee-form:employee-remove-dialog"
...>
...
</p:commandButton>
</h:panelGrid>
</p:column>
</p:dataTable>
<p:dialog ...
id="employee-remove-dialog">
</p:dialog>
</h:form>
प्रश्न:
क्यों एपी: datatable जरूरत रूट जेएसएफ आईडी को उपसर्ग करने के लिए? शायद यह मेरा कोड है, लेकिन पोस्ट किया गया उदाहरण मेरे लिए न्यूनतम लगता है। किसी भी मामले में, इसका उपयोग करने से परिणामस्वरूप पूरे आवेदन में संभवतः लंबी आईडी हो जाएगी।
मैं क्या गलत कर रहा हूं?
पुनश्च: मैं JBoss 7.1.1.Final, Mojarra 2.1.7, पीएफ 3.3.1
(+1) एल्गोरिदम पोस्ट करने के लिए धन्यवाद: यह एक ठोस मामले के लिए ठोस से अधिक मददगार है। – Ralph
