Portlet development: configuration updates only after refresh

[Lior Hadaya, geändert vor 11 Jahren.]

Hi,
I'm using Liferay EE 6.1.10 and I'm trying to develop my own portlet, using the plugins SDK, inheriting from MVCPortlet.

I followed this guide http://www.liferay.com/community/wiki/-/wiki/Main/Add+Config+Page+to+Plugin+Portlet in order to create a configuration jsp page that will appear as the Setup tab in the portlet's configuration.
In the setup tab I have one text box and a save button.
The view.jsp of my portlet displays the value that the user typed in the configuration.jsp page.

My problem is that after I click save, I don't see the green message saying the request completed successfully and the parameter doesn't update on my view.jsp.
Only after I close the configuration dialog and refresh the browser, the parameter change is reflected in my portlet's view.jsp.

What am I missing? This is the relevant code:

View.jsp

<% PortletPreferences preferences = renderRequest.getPreferences();
	
	String portletResource = ParamUtil.getString(request, "portletResource");
	
	if (Validator.isNotNull(portletResource)) {
		preferences = PortletPreferencesFactoryUtil.getPortletSetup(request, portletResource);
	}

	String param_name = preferences.getValue("pref-title","");
	
	%>
<br>
The title parameter is now &lt;%=param_name%&gt; <br>

Configuration.jsp

<%
	PortletPreferences preferences = renderRequest.getPreferences();
	
	String portletResource = ParamUtil.getString(request, "portletResource");
	
	if (Validator.isNotNull(portletResource)) {
		preferences = PortletPreferencesFactoryUtil.getPortletSetup(request, portletResource);
	}

	String param_name = preferences.getValue("pref-title","");
%>

<form action="<liferay-portlet:actionURL portletConfiguration=" true">" method="post" name="<portlet:namespace />fm"&gt; 
<input name="<portlet:namespace /><%=Constants.CMD%>" type="hidden" value="<%=Constants.UPDATE%>"> <br>
<table>
	<tbody><tr>
		<td>Title:</td>
		<td>
			&lt;%
				if (preferences != null) {
			%&gt;
				<input name="txtTitle" type="text" value="<%=param_name %>">
			&lt;%
				} else {
			%&gt;
				<input name="txtTitle" type="text" value="">
			&lt;%
				}
			%&gt;
		</td>
	</tr>
</tbody></table>
<input type="button" value="<liferay-ui:message key=" save">" onClick="submitForm(document.<portlet:namespace />fm);" /&gt;
<br>
</form>

ConfigurationActionImpl.java

public class ConfigurationActionImpl implements ConfigurationAction {

	@Override
	public void processAction(PortletConfig config, ActionRequest actionRequest, ActionResponse actionResponse) throws Exception {
		 
		String cmd = ParamUtil.getString(actionRequest, Constants.CMD);
		
		if (!cmd.equals(Constants.UPDATE)) {
			return;
		} 
		
		String title = actionRequest.getParameter("txtTitle");
		
		String portletResource = ParamUtil.getString(actionRequest, "portletResource"); 
		PortletPreferences prefs = PortletPreferencesFactoryUtil.getPortletSetup(actionRequest, portletResource); 

		//Read, validate, and then set form parameters as portlet prerferences //

		
		prefs.setValue("pref-title", title);
		prefs.store();

		SessionMessages.add( 
				actionRequest, config.getPortletName() + ".doConfigure"); 

	}

	@Override
	public String render(PortletConfig arg0, RenderRequest arg1,
			RenderResponse arg2) throws Exception {

		return "/configuration.jsp";
	}

}

Thanks a lot,
Lior

Anyone? please?

I have the same problem.... Did you solve it?

[Lior Hadaya, geändert vor 11 Jahren.]

No, it's still an open issue for me.

Have you found the solution for this yet?

[Lior Hadaya, geändert vor 11 Jahren.]

No, it's still an open issue for me.

Hi, I have found where the problem is, I am using 6.1EE.

http://www.liferay.com/community/wiki/-/wiki/Main/Add+Config+Page+to+Plugin+Portlet

SessionMessages.add(actionRequest, config.getPortletName() + ".doConfigure");
After this line, we need to add another line:
super.processAction(portletConfig, actionRequest, actionResponse);

Then it will show success message and update the portlet automatically.

Hello,

Thank you for the response as I have been trying to solve this for awhile. I eventually got the "Success" message to appear using a different technique but it never updated the view.jsp when I returned. So when I saw your reply, I thought I'd give it another try.

However, after adding the line you indicated, I now get a fatal exception error:
The method processAction(PortletConfig, ActionRequest, ActionResponse) is undefined for the type Object

When in Eclipse I can never get the processAction resolved in the line added:

super.processAction(portletConfig, actionRequest, actionResponse);

Eclipse gives the same message as the error when running it. It's as if I'm missing an Import, but I can't find anything missing.

You can only call the method on the super class if you have a super class. The OP's first post indicated they were just implementing an interface, not extending a superclass...

Is implementing the interface the right way to go? What's the other option that extends a superclass?
I still can't get this to work.. please advise

Thanks

Also, what worked for me before with displaying the parameter's value in view.jsp doesn't work anymore..

when I run this code

<% PortletPreferences preferences = renderRequest.getPreferences();
    
    String portletResource = ParamUtil.getString(request, "portletResource");
    
    if (Validator.isNotNull(portletResource)) {
        preferences = PortletPreferencesFactoryUtil.getPortletSetup(request, portletResource);
    }

    String param_name = preferences.getValue("pref-title","");
    
    %>
<br>
The title parameter is now &lt;%=param_name%&gt; <br>

It doesn't show the parameter's value. Validator.isNotNull(portletResource) returns false (i.e portletResource is null).

Any help would be greatly appreciated..

Thanks

I ended up using a different way to get the portletResource:

String portletResource = (themeDisplay.getPortletDisplay()).getId();

This worked, I can display the configuration value in the view but the original problem that I must refresh the page after saving the configuration settings in order for the view to update still exists.

[Lior Hadaya, geändert vor 11 Jahren.]

I will continue updating on my attempt to solve this hoping one of you might be able to step in and assist..

I began looking at how Liferay implements configuation.jsp pages, for the polls display portlet for example.
I see that polls display's configuration's page uses aui, like this:

<%
String redirect = ParamUtil.getString(request, "redirect");
questionId = ParamUtil.getLong(request, "questionId", questionId);
List<pollsquestion> questions = PollsQuestionLocalServiceUtil.getQuestions(scopeGroupId);
if (scopeGroupId != themeDisplay.getCompanyGroupId()) {
	questions = ListUtil.copy(questions);
	questions.addAll(PollsQuestionLocalServiceUtil.getQuestions(themeDisplay.getCompanyGroupId()));
}
%&gt;

<liferay-portlet:actionurl portletConfiguration="true" var="configurationURL" />

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

	<c:choose>
		<c:when test="<%= !questions.isEmpty() %>">
			<aui:fieldset>
				<aui:select label="question" name="preferences--questionId--">
	                          ...
			</aui:select>
			</aui:fieldset>
		</c:when>
		<c:otherwise>
		</c:otherwise>
	</c:choose>

	<aui:button-row>
		<aui:button disabled="<%= questions.isEmpty() %>" type="submit" />
	</aui:button-row>
</aui:form>
</pollsquestion>

Does this mean I need to use aui too?
I tried to implement my configuration page in a similar way but I get an exception when using aui:form tag:

 java.lang.NoClassDefFoundError: com/liferay/portal/kernel/servlet/ DirectServletContext

Any thoughts?

Thanks

Hi Lior,

Were you finally able to solve this issue?

If you're using Liferay IDE, you can just check Configuration during new project wizard (check custom) to create a empty configuration page.
This is probably the easiest the surest way to create a configuration page.

[Lior Hadaya, geändert vor 11 Jahren.]

I eventually implemented this differently, with a spring portlet.
I have a method in the Controller that returns the configuration values and I call it using AJAX after the user saves the configuration.

[Mikko Torri, geändert vor 11 Jahren.]

As described here instead of

SessionMessages.add(actionRequest,
config.getPortletName() + ".doConfigure");

use

SessionMessages.add(actionRequest, 
portletConfig.getPortletName() + SessionMessages.KEY_SUFFIX_REFRESH_PORTLET,
portletResource);

It will reload the portlet automatically.
