Changing theme dynamically

[binnyg]

Is there a way to intercept and change theme dynamically?

Scenario is user belongs to an organization and each organization has a theme and based on user organization I want to set the theme.

Is this doable?

we did it by using a custom:

org.jboss.portal.core.aspects.controller.PageCustomizerInterceptor

which determines the users theme and provides it into the request:

...
serverInvocation.getServerContext().getClientRequest().setAttribute(ATTR_VIEW_THEME, theme);
...

and a custom:

org.jboss.portal.theme.tag.ThemeTagHandler

which reads the theme out of the request:

...
 PageContext pageContext = (PageContext) getJspContext();
 HttpServletRequest request = (HttpServletRequest) pageContext.getRequest();
 PortalTheme theme = (PortalTheme) request.getAttribute(PageCustomizerInterceptor.ATTR_VIEW_THEME);
...

and writes its elements onto the page:

...
JspWriter outWriter = pageContext.getOut();
Iterator it = theme.getElements().iterator();

while (it.hasNext())
{
 ThemeElement te = (ThemeElement) it.next();
 String elementString = te.getElement();

...

 outWriter.println(elementString);
}
...

Thank you. This is what I am looking for and will try this approach.
