skip autoUpdate="true" with somethig like limitRender

[eunnini]

Hello,

I have a problem with p:messages with autoUpdate="true". Richfaces has a possibility to restrict autoUpdate attribute with limitRender="true". Does primefaces has some possibility

Problem:
open dialog, click on submit button and call oncomplete="dlg.hide()". But, if I have some listener inside dialog, like close dialog that calls some generic method, then p:messages component with autoUpdate="true" is called twice and message disappear (e.q. Delete successful) - The message for deletion is showing correctly, but immediately disappear because of second autoUpdate called by close dialog listener

Regards

we had exactly the same problem and found no solution via primefaces..

we "solved" it by creating our own listener which adds our messages to the update entities, but only when there are new messages in facescontext.
this way our messages are still alive, when closelistener is fired.
only known "bug".. when the closelistener adds a message too, the message from the actionlistener gets lost.. but we dont have this case in our application right now.

Hi,

There isn't concept of "limitRender" in PrimeFaces. I have implemented this behavior by putting a special flag in request scope. E.g. I have p:messages and p:growl and want to show sometimes only p:growl

Code: Select all

<p:growl id="growlNotification" showDetail="true" showSummary="true" rendered="#{not empty requestScope['growlOnly'] and requestScope['growlOnly'] == true}"/>

P.S. RequestContext can't help here.

Thanks guys!

Alex, could you give me some code snapshot about listener that you implemented. We also do not have situation from "knowing bug" that you mention

Please let me know how to use P:poll which should update only specified components and skip other autoupdate components.

I tried different workaround but did not got sucess.

In Richfaces we have limitrender.But we do not have this knid of functionality in primefaces.

If someone know any other workaround please post the message .

Thanks,
Roshan

Same problem here!
Is there any solution?

You can use rendered attribute to avoid auto updating. In my case it is poll component which is clearing messages. If poll is triggered, its client ID appears as javax.faces.source request parameter which can be used in expression language.

Code: Select all

<h:form id="myForm">

    <p:messages autoUpdate="true"
        rendered="#{param['javax.faces.source'] != 'myForm:myPoll'}" />

    <h:panelGrid id="myPanel">
        ...
        ...
        ...
    </h:panelGrid>

    <p:poll id="myPoll" autoStart="true" global="false" interval="15"
        update=":myForm:myPanel" listener="#{myBean.myListener}" />

</h:form>

Alternative solution is binding poll.

Code: Select all

<p:messages ... rendered="#{param['javax.faces.source'] != poll.clientId}" />
...
<p:poll binding="#{poll}" ... />
