I just tried the alpha-3 build but i'm getting an exception before i can even see a single page the exception that show on screen is this:

java.lang.NullPointerException
org.apache.tapestry.engine.AbstractEngine.service(AbstractEngine.java:263)


After some debugging inside tapestry i found the the cause of the error is that AbstractEngine is not being able to get the request cycle.
So line 230 of org.apache.tapestry.engine.AbstractEngine that is:

cycle = _infrastructure.getRequestCycleFactory().newRequestCycle(this);

throws an exception with the following message:

org.apache.hivemind.ApplicationRuntimeException: Error building service tapestry.request.RequestCycleFactory: Error at jar:file:/C:/java/jakarta-tomcat-5.5.7/webapps/siges/WEB-INF/lib/tapestry-4.0-alpha-3.jar!/META-INF/tapestry.request.xml, line 206, column 88: Unable to read property serviceEncoders of object <SingletonProxy for tapestry.url.LinkFactory(org.apache.tapestry.services.LinkFactory)>: java.lang.reflect.InvocationTargetException [jar:file:/C:/java/jakarta-tomcat-5.5.7/webapps/siges/WEB-INF/lib/tapestry-4.0-alpha-3.jar!/META-INF/tapestry.request.xml, line 203, column 21]


After looking at line 206 i noticed that only "strange" thing about it was that the "set-object" element was broken in half with a new line. So i removed the new line and the error was gone.


It looks like a bug, that i wanted to check with the mailing list first before i created the bug in JIRA.
So, is it ?


Cheers
