我正在尝试在 ajax 命令按钮请求后更新 primefaces 表单(向导第一步)但没有成功。进行实际 ajax 调用的命令按钮位于对话框中。我想在提交请求后强制我的视图刷新。
命令按钮从数据表中删除记录。它工作正常,记录被删除,但是当对话框被隐藏时,数据表继续显示已删除的记录。我想以某种方式强制它刷新。有任何想法吗?我可以从我的支持 beanreviewManagerBean.deleteProtocol()
方法中做到这一点吗?
这是代码(我的 BackBean 是 viewScoped):
<h:form id="reviewManagerForm">
...
<pe:masterDetail id="masterDetail" level="#{reviewManagerBean.currentLevel}" showBreadcrumb="false" selectLevelListener="#{reviewManagerBean.levelListener}" >
<f:facet name="header" >
<h:panelGroup layout="block" style="margin-top: 10px;" >
<h:panelGroup styleClass="levelTitle ui-state-default ui-corner-all wizard-breadcrumbs#{reviewManagerBean.currentLevel eq 1 ? 'ui-state-hover' : ''}">
<h:outputText value="1: Protocol picker"/>
</h:panelGroup>
...
<p:messages id="mainMessagesPanel" showDetail="true" closable="true" />
</h:panelGroup>
</f:facet>
<pe:masterDetailLevel level="1">
<p:panel id="panel1" header="List of available protocols">
<p:dataTable id="protocolsDataTable" var="cRProtocol" rowKey="#{cRProtocol.revProtId}" value="#{reviewManagerBean.cRReviewProtocolList}"
widgetVar="protocolsTable"
...
selection="#{reviewManagerBean.selectedReviewProtocol}"
selectionMode="single" >
...
<p:ajax event="rowSelect" listener="#{reviewManagerBean.setSelectedRow}" />
<p:ajax event="rowUnselect" listener="#{reviewManagerBean.unsetSelectedRow}"/>
...
<p:column sortBy="#{cRProtocol.revProtTitle}" headerText="Title" style="width:200px;text-align:center;">
<h:outputText value="#{cRProtocol.revProtTitle}" />
</p:column>
...
<p:column>
<p:commandButton value="Delete" onclick="dlg5.show()"
update=":reviewManagerForm:deleteSingleProtocol"
disabled="#{reviewManagerBean.checkifProtocolIsOpen(cRProtocol)}"
ajax="true" process=":reviewManagerForm:deleteSingleProtocol" />
</p:column>
</p:dataTable>
</p:panel>
...
<p:dialog id="dialog-deleteprotocol" header="Delete Image Type" widgetVar="dlg5" dynamic="true" modal="true" resizable="false">
<p:panelGrid id="deleteSingleProtocol">
<p:row>
<p:column>
<h:outputText value="Id:" style="font-weight:bold; padding-right:10px" />
</p:column>
<p:column>
<h:outputText value="#{reviewManagerBean.selectedReviewProtocol.revProtId}" />
</p:column>
</p:row>
...
<p:column>
<p:commandButton id='protocolDelete'
value='Delete'
action='#{reviewManagerBean.deleteProtocol()}'
ajax="true"
onclick="dlg5.hide()" icon="ui-icon-disk"
update=":reviewManagerForm:protocolsDataTable"
process=":reviewManagerForm:deleteSingleProtocol" />
</p:column>
</p:row>
</p:panelGrid>
</p:dialog>
