LoadStyleStrategy does not work in portlet/facelet environment.
---------------------------------------------------------------
Key: RF-2351
URL: http://jira.jboss.com/jira/browse/RF-2351
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.1.4, 3.1.3
Environment: JBoss Portal 2.6.3-GA / JBoss [Trinity] 4.2.2.GA (build:
SVNTag=JBoss_4_2_2_GA date=200710221139)
Java version: 1.5.0_11,Sun Microsystems Inc.
Java VM: Java HotSpot(TM) Client VM 1.5.0_11-b03,Sun Microsystems Inc.
OS-System: Windows 2000 5.0,x86
Reporter: Andreas Chlupacek
A JSR-168 portlet project using RichFaces 3.1.3-GA and facelets was deployed on JBoss
Portal 2.6.3. In the project's web.xml, the context-parameter
org.richfaces.LoadStyleStrategy was specified. But regardless of the value assigned to
this parameter (DEFAULT, NONE, or ALL), the generated markup always looks the same: The
document will always contain references to the individual per-component xcss resources.
Neither NONE nor ALL seem to make a difference. This behaviour was observed with 3.1.3-GA
as well as with 3.1.4-GA and 3.1.4-SR1.
Steps to reproduce:
===================
Set up a portlet application with the following artefacts:

Observed behaviour:
===================
The setting for LoadStyleStrategy seems to be ignored in a portlet/facelet application.
Neither NONE nor ALL make a difference for the references to the CSS files. They are
always referenced per-component, in the middle of the document's markup. This leads to
the effect that custom CSS classes (specified for example via headerClass or styleClass
attributes) are partially overwritten by RichFaces' component-specific styles. In the
example above, none of the attributes of .panelHead or .paneyBody will ever have any
effect since they are superseded by .dr-pnl-h, .dr-pnl-b, .panelBody and .dr-pnl.
This happens regardless of the RichFaces version or combination of RichFaces and
Portletbridge JARs (3.1.3-GA, 3.1.4-GA and 3.1.4-SR1). Any combination of
LoadStyleStrategy and COMPRESS_STYLE attributes was tested.
Expected behaviour:
===================
The attributes ALL and NONE should cause loading of no stylesheets at all or a single
consolidated CSS, respectively.
