What you are exactly looking for?

If you are looking to store value in portlet prefrence then below is the code.

final PortletPreferences prefs = portletRequest.getPreferences();
prefs.setValue("paramName", "paramValue");
prefs.store();

Thanks & Regards,

Alloy UI is just an user interface library so it won't save any data.

Follow Amit's instructions and create a Java class which is invoked from your FORM if you want to save your data.

Its is working with Liferay 6.1

Define your AUI element with below syntax

<aui:input name="preferences--showFeedTitle--" type="checkbox" value="<%= showFeedTitle %>" />

It should follow pattern like preferences--paramName-- .

And make sure you use below Configuration class in your liferay-portlet.xml

<configuration-action-class>com.liferay.portal.kernel.portlet.DefaultConfigurationAction</configuration-action-class>

By using this way we dont need to write any code to store form element value into preferences . DefaultConfigurationAction class will detect form element with specified syntax and store the same in preference for you.

In case if you want to retrieve value from preference then directly use

preferences.getValue("showFeedTitle")

// No need to use that syntax to get value

Interesting. Have to test it out.

The normal way to save configuration is outlined in the page below.

Yes its interesting and it will reduce code to store form elements values in preferences.

Listed same thing on my blog as well.

I would definitely like to give a try for it. It's something new today I learned from you.

Thanks for sharing this information.

Hi Jitendra

Any idea how can I use the same mechanism for dropdown if I am selecting multiple values ?

Thanks

Hi, what if the preferences I'm dealing with have multiple values? Any fast way to update the value with preferences--parameters-- ??

I'll explain better with an example. Suppose I have in my portlet.xml

<preference>
           <name>MultipleValues</name>
           <value>Number 2</value>
           <value>Number 3</value>
 </preference>

And in my config.jsp

<%
PortletPreferences preferences = renderRequest.getPreferences();
String portletResource = ParamUtil.getString(request, "portletResource");
PortletPreferences prefs =
           PortletPreferencesFactoryUtil.getPortletSetup(request, portletResource);
String [] mul = prefs.getValues("MultipleValues", 
                                    new String []{"", ""});
%>

<aui:form action="<%= configurationURL %>" method="post" name="fm">
    <aui:input name="<%= Constants.CMD %>" type="hidden" value="<%= Constants.UPDATE %>" />

    <aui:input name="preferences--MultipleValues--" type="text" value="<%= mul[0] %>" />
    <aui:input name="preferences--MultipleValues--" type="text" value="<%= mul[1] %>" />

    
    <aui:button-row>
       <aui:button type="submit" />
    </aui:button-row>
</aui:form>

After the submit the preference "MultipleValues" will be updated only with one value and it changes from a String[2] to a simple String.

Any way to specify a in the aui to refers to the index like preferences-MultipleValues-[0] ??

Thank you in advance for the help.

Cheers
