Can't get actions to work in Liferay Faces

Hi Chris,

It was my pleasure -- so glad to hear that it is working for you now. Thanks for hanging in there and for using Liferay Faces.

Kind Regards,

Neil

Hey, it's working! There is much dancing going on here!

The other thing we had on that page was a button that when clicked would display the current date selected in the calendar, and that worked, as well!

I also changed the calendar tag to look like this:

<p:calendar id="myCal" mode="inline" value="#{testBean.myDate}">
	<p:ajax event="dateSelect" listener="#{testBean.updateDate}" update="myMsgs" />
</p:calendar>

and added the output of myDate:

<h:panelgroup id="myMsgs">
	#{testBean.myDate}
</h:panelgroup>

Thank you so much for seeing this through with me, Neil!

The version of Liferay IDE I have installed is 2.2.1.201411200728-ga2, and Eclipse is Luna 4.4.1, so I am installed the E4 RCP Patch in Eclipse. Thanks for the links, as well.

Hi Chris,

I found the problem -- the <portlet>...</portlet> section of your WEB-INF/liferay-portlet.xml descriptor was missing some entries. When I changed it to look like this:

    <portlet>
        <portlet-name>my-calendar-portlet</portlet-name>
        <icon>/icon.png</icon>
        <instanceable>true</instanceable>
        <remoteable>true</remoteable>
        <requires-namespaced-parameters>false</requires-namespaced-parameters>
        <ajaxable>false</ajaxable>
        <header-portlet-css>/css/main.css</header-portlet-css>
        <footer-portlet-javascript>/js/main.js</footer-portlet-javascript>
        <css-class-wrapper>my-calendar-portlet-portlet</css-class-wrapper>
    </portlet>

... then it started working.

The problem stems from the fact that our Ivy project templates are missing the ajaxable and requires-namespaced-parameters elements. So every time a new project is created, they need to be added.

If you are using Liferay IDE to develop your portlets, then a potential workaround for this bug should be found in verson 2.0.1 (and higher) of Liferay IDE, as documented in IDE-1389. As of the time of this writing, the latest version of Liferay IDE is 2.2.1, as documented in a recent blog post by Greg Amerson.

Kind Regards,

Neil

Thanks, Neil! I'm attaching the project which lives under liferay-plugins-sdk-6.2\portlets if that helps to make sure working on the same code. The view in question is under docroot/view/my-calendar-portlet, and it currently has p:ajax instead of f:ajax but you can easily switch it back.

Chris

Hi Chris,

If it is OK with you, let's keep the conversation going here in the Liferay Faces forums. I should have some time later today to take a closer look. I'll get back to you.

Kind Regards,

Neil

Hi, Neil,

Thanks for the response (which you were also kind enough to post on stackoverflow, where I posted there because this post was marked as spam and the long US Thanksgiving holiday delayed administrators from clearing it).

As I said on stackoverflow, the changes you suggested did not seem to fix the issue. I also tried using p:ajax, but to no avail.

Given my experience with JSF, I'm confident the Bean and .xhtml file are correct. I'm thinking the problem is either in the Liferay faces bridge itself or there is some configuration item I am missing somewhere. Being new to Liferay, I have no idea where to look.

Hi Chris,

I am not certain but this might be caused by FACES-1993. For now, I recommend that you try removing the paragraph that surrounds the h:panelGroup component tag:

<p>...</p>

And then try this:

<f:ajax render=":someForm:output" event="keyup" />

Kind Regards,

Neil

We are having issues with trying to use Liferay Faces along with any JSF components to fire action events.

I've gone through the first part of the "Developing JSF Portlets" instruction page up until the Internationalize JSF Portlets section with success. I went ahead and added some other JSF components with some success as well, however, events are not working.

The goal is to have a text box where the user can change the default text of "World", and a text area will update by AJAX on every keystroke with "Hello, XXX" (where XXX is the text from the box).

I am getting a postback to the server. The DebugPhaseListener is resulting in only BEFORE/AFTER RESTORE_VIEW 1, and BEFORE/AFTER RENDER_RESPONSE 6. There are no phases in between, which I presume is part of the problem.

Here are all of the assets and code that I think are relevant to figure out what is going on. Any help you can give would be greatly appreciated.

UPDATED: Using Liferay 6.2, running in Eclipse with the latest Tomcat bundle and latest eclipse plugin from the liferay update site. Java 1.7.0_71.
UPDATED 2: Yes, I have tried out the view.xhtml and TestBean.java in a separate JSF project and it works.

view.xhtml:
