Due to the conflicts between the version of YUI we currently load and use in ICEfaces 2 and the version that is loaded and used by Liferay, that issue needs to be resolved first.

ACE Showcase Portlet Testing

Liferay 6.0.5

It's possible to load a single ICEfaces portlet in the page and basic functionality appears to be there. However, there are two major issues:

1) Still appears to be a YUI conflict even when both Liferay and ICEfaces are both using the same version (3.2). Likely still due to the extra evaluation of YUI code which appears to still cause an issue. The problem now is that, since ICEfaces loads last, it's causing some re-evaluation of scripts that Liferay is dependent on for it's UI. The end result is that, after the first ICEfaces ACE portlet has been added to the page, you can no longer move it around or add any other portlets to the page because the Liferay UI no longer functions correctly. I'm seeing the following JS issues several times in the console:

Uncaught TypeError: Cannot read property 'event' of undefined
m.use.H everything.jsp:1
v.each.w everything.jsp:1
m.use.H everything.jsp:1
m.use everything.jsp:1
(anonymous function) ace:53

2) There seems to be some issues around loading CSS properly. I see these types of things in the Chrome console regarding the resources where the URLs to be imported are not properly resolving to what the portlet requires.

/* load core styling from YUI library */
@import url('http://localhost:8080/web/guest/ace?p_p_cacheability=cacheLevelPage&p_p_col_count=1&p_p_col_id=column-1&p_p_id=checkbox_WAR_aceshowcaseportlet_INSTANCE_PG9o&p_p_lifecycle=2&p_p_mode=view&p_p_state=normal');
@import url('http://localhost:8080/web/guest/ace?p_p_cacheability=cacheLevelPage&p_p_col_count=1&p_p_col_id=column-1&p_p_id=checkbox_WAR_aceshowcaseportlet_INSTANCE_PG9o&p_p_lifecycle=2&p_p_mode=view&p_p_state=normal');

Liferay 5.2.3

No JS conflict here but there are other problems.

1) The first interation with any portlet causes the following:

Caused by: java.lang.ClassCastException: com.sun.faces.application.view.StateHolderSaver cannot be cast to [Ljava.lang.Object;
at javax.faces.component.UIOutput.restoreState(UIOutput.java:251)
at com.sun.faces.application.view.StateManagementStrategyImpl$1.visit(StateManagementStrategyImpl.java:261)
... 121 more

2) The same CSS resource loading/importing issues as described above for Liferay 6.

The ACE Showcase example has files and build target for creating a portlet version. Due to ICE-6164, only the File Entry component currently works as a portlet at the time being. Future work to re-able the other portlets are dependent on work in ICE-6164.
