Displaying an Article or a Wiki Entry in Pop-Up

[Marc Grünewald, modifié il y a 11 années.]

Hello everyone,

once again I need your Help. I'm currently developing several Portlets and I'm trying to provide a simple and clean help for these Portlets. I want to realize that, by writing a Liferay Article and implement a Button in the Portlets which preferrably opens that article in a Pop-Up. For your Information, I'm using Icefaces, JSF and Liferay 6.1.?

Hope you guys can help


Cheers Marc

You can use the ICEfaces3 ace:dialog component tag for the popup. For the article text, you can retrieve that from a JSF model managed-bean like this:

@ManagedBean
public class HelpModelBean {

    private String text;

    public String getText() {
        if (text == null) {
            LiferayFacesContext liferayFacesContext = LiferayFacesContext.getInstance();
            ThemeDisplay themeDisplay = liferayFacesContext.getThemeDisplay();
            long groupId = liferayFacesContext.getScopeGroupId() // assumes that the help text article is in the current site/community
            String articleId = "1234"; // the id of the help text article
            String languageId = LanguageUtil.getLanguage(liferayFacesContext.getLocale());
            text = JournalArticleLocalServiceUtil.getArticleContent(long groupId,
		java.lang.String articleId, java.lang.String languageId,
		com.liferay.portal.theme.ThemeDisplay themeDisplay)
        }
        return text;
    }
}

Hi Neil,

sorry to bother you again, but I tried your code(in fact I fetch the content of a WikiPage) and it is doing what it should but just displaying unformatted plain text isn't really user friendly to read... Is it possible to show the whole wikipage in the ace:dialog?

Best Regards

Is your content using stored as Wiki entries (like the ones created with the Liferay Wiki portlet) or is the content stored as Web Content articles?

[Marc Grünewald, modifié il y a 11 années.]

Its created using the Wiki-Portlet from the Control Panel.

[Neil Griffin, modifié il y a 11 années.]

OK for retrieving Wiki content from the Liferay database that can be rendered as HTML, then I recommend that you look at the following JSP found in the Liferay Portal source code: portal-web/docroot/html/portlet/wiki/view_page_content.jspf

You can use similar Java Scriptlet code in your JSF model managed-bean to retrieve the Wiki article.

Okay thanks, I'll look into it. Just out of curiosity, is there a huge difference between displaying an Article and a Wiki Page? If yes, what are the advantages/disadvantages? Basically I want to provide a Help for my Custom Portlet which should be visible after a button-click. Whether that renders in a pop-up or in a new Page is not that important, a pop-up is probalby a little more user friendly though.

[Neil Griffin, modifié il y a 11 années.]

For the purpose of rendering Help, there isn't much difference. I think that Web Content articles might be a better fit though, because they are similar to individual text files which are not necessarily related to each other. Wiki articles tend to be part of a Wiki Page hierarchy with hyperlinks to related Wiki content.

[Marc Grünewald, modifié il y a 11 années.]

Hmm I see, then I would take your advice and stick with Web Content articles. Is there a similiar jsp(f)-File for me to take a look at? Sorry for asking all that... still a pretty newbie to all that stuff. Thanks anyway for all your help so far, I really apreciate it.

Best Regards

No problem, here's the file I think you're asking about:
portal-web/docroot/html/portlet/journal/view_article.jsp

[Marc Grünewald, modifié il y a 11 années.]

Hello Neil, I gave it a try and it works!
I "exported" the code of the jsp mentioned to a Bean and accessed the article content with an ice:outputext and "escape" disabled.
The content shwos inside a ace:dialog as you've suggested. Thanks you very much, that really really helped. Have a nice day! Cheers Marc
