Display a formatted text / message on p:confirmDia

Question

When a row in <p:dataTable> is right-clicked, <p:contextMenu> appears with a delete option. When this option is clicked, <p:confirmDialog> appears with two buttons Yes and No - a conformation warning about deleting the current row as follows.

<p:contextMenu for="dataTable">
    <p:menuitem oncomplete="confirmDelete.show()"
                value="Delete"
                update="confirmDialog"
                process="@this dataTable"
                actionListener="#{testManagedBean.deleteActionListener}"
                icon="ui-icon-close" ajax="true"/>
</p:contextMenu>

<p:confirmDialog id="confirmDialog"
                 widgetVar="confirmDelete"

                 message="#{testManagedBean.message}"

                 header="Message"
                 severity="alert"
                 closeOnEscape="true"
                 showEffect="slide"
                 hideEffect="fold"
                 appendTo="@(body)"
                 closable="true">

    <p:commandButton id="btnYes"
                     value="Yes"
                     process="@this"
                     oncomplete="confirmDelete.hide()"
                     actionListener="#{testManagedBean.deleteActionListener}" 
                     update="dataTable"/>

    <p:commandButton id="btnNo"
                     value="No"
                     onclick="confirmDelete.hide()"
                     type="button" />
</p:confirmDialog>

Is there a way to set the message attribute with a formatted message on this dialog.

For example, the property testManagedBean.message in its managed bean is set to a string like

You are about to delete <font color='#ff0000'>2</font> rows. <br/>This action will never be undone. <br/>Are you sure?

The confirm dialog displays this string as a whole. HTML in this string should be interpreted as HTML. I don't see any attribute like escape in <p:confirmDialog>.

Is there a way to display this string as a formatted message.

Answer 1

I found an ugly solution nesting of <f:facet name="message"> within <p:confirmDialog>.

<p:confirmDialog id="confirmDialog"
                 widgetVar="confirmDelete"

                 header="Message"
                 severity="alert"
                 closeOnEscape="true"
                 showEffect="slide"
                 hideEffect="fold"
                 appendTo="@(body)"
                 closable="true">

    <p:commandButton id="btnYes"
                     value="Yes"
                     process="@this"
                     oncomplete="confirmDelete.hide()"
                     actionListener="#{testManagedBean.deleteActionListener}"
                     update="dataTable"/>

    <p:commandButton id="btnNo"
                     value="No"
                     onclick="confirmDelete.hide()"
                     type="button" />

    <f:facet name="message">
        <h:outputFormat value="#{testManagedBean.message}" escape="false"/>
    </f:facet>
</p:confirmDialog>

Removing the message attribute from <p:comfirmDialog> and nesting <f:facet name="message"> inside it.

Note : <h:outputFormat> is only needed, if one or more parameters need to be passed by means of nested <f:param> to be substituted in respective placeholders ({0}) in the message text. Just keep on using <h:outputText escape="false">, if no such parameters need to be passed.
