The EL resolver is defined via a faces-config file, so it is
automatically enabled for Woodstock. Technically, you could override
this at the application level (i.e. via your own faces-config.xml). For
example, if there is a Seam resolver, you could ensure it is called first.
<application>
<el-resolver>com.sun.webui.jsf.faces.UIComponentELResolver</el-resolver>
<el-resolver>com.sun.webui.jsf.faces.ThemeELResolver</el-resolver>
<el-resolver>com.sun.webui.jsf.faces.DataProviderELResolver</el-resolver>
</application>
That said, your stack trace refers to line 72 of UIComponentELResolver.
This particular line invokes a simple log utility class. Basically, we
print out the class name and the property to be retrieved.
70: public Object getValue(ELContext context, Object base, Object
property) {
71:
72: log("getValue(ctx, " + base + "," + property + ")");
Our LogUtil uses standard J2SE logging, so I don't understand why Seam
would be involved here?

I have a couple more questions for you:
1. Is logging enabled?
2. What version of Java are you using?
3. Do you have commons-logging.jar in your class path?
4. Would you be willing to test a new jar, providing we strip out the
logging?
