Opening a portlet in dialog from web content

Recently I was asked how to do this! Well, it's rather simple (providing you understand the limitations of accessing portlets without permission, and portlets that are not allowed to be loaded dynamically; a.k.a. add-default-resource, and so on).

Here goes!

First I created a simple web content structure/type with the following definition:

<root>
    <dynamic-element name='portlet-id' type='text' index-type='' repeatable='false'></dynamic-element>  
    <dynamic-element name='parameters' type='text' index-type='' repeatable='true'>         
        <dynamic-element name='value' type='text' index-type='' repeatable='false'></dynamic-element>
    </dynamic-element>
</root>

Then I created the following web content template:

 

<script type="text/javascript" charset="utf-8">
    AUI().ready('aui-dialog','aui-dialog-iframe','liferay-portlet-url', function(A) {
        var url = Liferay.PortletURL.createRenderURL();
        url.setPortletId("${portlet-id.data}");
        url.setWindowState('pop_up'); 

        #foreach ($parameter IN $parameters.getSiblings())
            url.setParameter("${parameter.data}", "${parameter.value.data}");
        #end  

        window.myDialog = new A.Dialog(
            {
                title: 'My Dialog',
                width: 640,
                centered: true
            }
        ).plug(
            A.Plugin.DialogIframe,
            {
                uri: url.toString(),
                iframeCssClass: 'dialog-iframe'
            }
        ).render();
    });
 </script>

 

As you can see there is a place for setting the portletId to craete an URL for, as well as a repeated section for assigning parameters to the url.

Creating an article with the Portlet Id value of 3 results in a dialog opening with the search portlet.

 

You can expand this simple example into whatever you like. The Alloy Dialog plugin is very rich and the Liferay.PortletURL library provides a complete API for creating all of the PortletURL types defined by the portlet spec.

 

Enjoy!

Very nice - thanks!
A shame it does not work when you use https.

How about applying my fix from : http://issues.liferay.com/browse/LPS-14965

(pretty please)
Done! https://github.com/brianchandotcom/liferay-portal/pull/882
sweet! thanks
Hi,
I’m getting an ugly “Java null pointer exception” when I try to run Social Office on MySQL. I have tried to find the solution online but there is not much help out there. I have even posted in one of the forums, but there’s been no response in the last two days.

I know that this is not the right place for this question, but i had no other solution. So im just asking everyone who is involved with Social Office at some point or the other.

I’m posting a few excerpts from the log file here. Please let me know if you can suggest me some workaround for this error.

Hi all,

Where could I found API doc about Liferay, PortletURL objects?

Thanks
As far as I can tell that is still in the "to be documented" queue.

Here is the link to the js source though: https://github.com/liferay/liferay-portal/blob/master/portal-web/docroot/html/js/liferay/portlet_url.js
Hio, i try to do the same thing but I just want to display 'Article' in popup. I wrote something like that :

var url = Liferay.PortletURL.createRenderURL();
url.setPortletId('56');
url.setWindowState('pop_up');
url.setParameter("struts_action", "/journal/view_article");
url.setParameter("groupId","18");
url.setParameter("articleId","10460");
url.setParameter("version","1.0");

Only this message in the popup :
"Portlet is temporarily unavailable. "

anyone could help me, please?
Try this portletId instead "56_INSTANCE_0000". That ID is whitelisted and should allow you to open this portlet dynamically.

Note that for security reasons most portlets have to be added to the resource check whitelist (portlet.add.default.resource.check.whitelist) before they allow you to open them dynamically otherwise any enterprising hacker could open any portlet in the system using javascript in a browser's scripting console.
thanks Ray but where do i modify these properties? In portal-ext.properties?
Change the portletId in your code, and the whitelist in portal-ext.properties.

Make sure to "append", new values to the defaults of the property. The defaults for 6.1 are here: https://github.com/liferay/liferay-portal/blob/6.1.x/portal-impl/src/portal.properties#L467
i set this in porta-ext.properties :
portlet.add.default.resource.check.enabled=true
portlet.add.default.resource.check.whitelist=58,56_INSTANCE_0000,86,87,88,103,113,145
and now there's no longer ""Portlet is temporarily unavailable. " but popur is clear.

in my console :
16:11:39,459 ERROR [RequestProcessor:676] Invalid path was requested /journal/view_article
16:11:39,459 ERROR [PortletRequestProcessor:363] User ID null

It looks fishy! Try setting the portlet mode (to "view").
nothing's better. Maybe it's a problem of struts path. In my liferay-portlet.xml :
<portlet>
<portlet-name>56</portlet-name>
<icon>/html/icons/journal_content.png</icon>
<struts-path>journal_content</struts-path>
......
i've the solution.

Summarizing then, with Liferay 6.0.6 CE :

url.setPortletId('56_INSTANCE_0000');
url.setWindowState('pop_up');
url.setParameter("struts_action", "/journal_content/view");
url.setParameter("groupId","18");
url.setParameter("articleId","17106");

My mistake was on the struts_action path. Look at liferay-portlet.xml and struts-config.xml. It's very important not to forget te "groupId". For "whitelist", see above. And thanks to Ray for his help.
