Hi!
I need to render some text containing links i a JSF component. I
cannot render a full commandLink element, since the data comes from a
content management system and the contract allows me to only modify
the href attribute of the anker element. The whole thing runs under
Liferay, a portlet container.
The solution I came up with is:
- declare a outputText element in the jsp and use its binding
attribute to create my own UIComponent.
- my UIComponent renders its children (getRendersChildren returns true)
- override encodeChildren and output the text while modifying the href
attribute of the href tokens.
I can click the link in the rendered page but the lifecycle gets
somehow distorted, because the viewrott is not restored properly, i.e.
The RestoreViewExecutor cannot restore the view. T
he result is that the lifecycle is interrupted and the request doesn't
get through to the "Invoke Application" phase.
Here is how I create the action link: ( the code is mostly copied from
org.apache.myfaces.shared_impl.renderkit.html.HtmlLinkRenderBase
String viewId = "/article/article.jsp";
if (PortletUtil.isRenderResponse(context)) {
RenderResponse response =
(RenderResponse)context.getExternalContext().getResponse();
PortletURL url = response.createActionURL();
url.setParameter(MyFacesGenericPortlet.VIEW_ID, viewId);
url.setParameter(PARAM_ITEMID, hrefToken.getLinkData());
url.setParameter(PARAM_ITEMTYPE, hrefToken.getLinkType().toString());
return url.toString() + '#';
}
Is there a better way of generating an action url. This implementation
has a hard-coded navigation and is so ugly. There must be a better
way.
Any ideas are much appreciated.
Cheers
Martin
