set a PrimeFaces theme

[nidheesh]

how to set a PrimeFaces theme? I have downloaded a aristo-1.0.0 jar and added the following code in web.xml file .

<context-param>
<param-name>primefaces.THEME</param-name>
<param-value>aristo</param-value>
</context-param>

but not working!Any idea?

I have a quite similar problem with PF 3.0 M4. I am using my own theme and it seems it's broken in M4 because it works fine on M2 and M3.

Code: Select all

 <!-- <context-param>
    <param-name>primefaces.THEME</param-name>
    <param-value>none</param-value>
  </context-param> -->

Please try theme version 1.0.1 (not 1.0.0) for 3.0 M release

@jguerra, I created an issue yesterday: http://code.google.com/p/primefaces/iss ... il?id=2696

I had the same problem, but got it to work with this:

Code: Select all

<context-param>
        <param-name>primefaces.THEME</param-name>
        <param-value>#{preferences.theme.name}</param-value>
</context-param>

if you look at the head renderer, you see that the theme loaded would then be primefaces-{whateverStringyourBeanReturns}/theme.css. So I no longer specify a theme in on my page: it's now set by head renderer using value supplied by my bean (<param-value>#{preferences.theme.name}</param-value>).

org.primefaces.renderkit.HeadRenderer (excerpt)

Code: Select all

String theme = "aristo";
        String themeParamValue = context.getExternalContext().getInitParameter(Constants.THEME_PARAM);

        if(themeParamValue != null) {
            ELContext elContext = context.getELContext();
            ExpressionFactory expressionFactory = context.getApplication().getExpressionFactory();
            ValueExpression ve = expressionFactory.createValueExpression(elContext, themeParamValue, String.class);

            theme = (String) ve.getValue(elContext);
        }

        encodeTheme(context, "primefaces-" + theme, "theme.css");

I assume that if you completely leave out the primefaces.THEME param, theme will default to aristo.

"none" keyword support enabled again, this was a regression after setting default theme to aristo, thanks!

By the way if you use your own theme, I suggest creating it following PF theme conventions so you can swap easily.
