Direct Access to Page variables
Hi All,
I've seen examples from the component ref (i.e. RadioGroup) using @PromoPage@Variable.
How do I implement this? It seems that when I usedit or based my code from the example, an error appeared:
Unable to initialize property activeonly of inpowered.admin.promo.pages.PromoPage$Enhance_24@1c235fe[promo]: Could not load class PromoPage from [ClassLoader: [[C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\classes], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/axis-ant.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/axis.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/bsf-2.3.0.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/comm.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-beanutils-1.6.1.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-codec-1.2.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-collections-2.1.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-digester-1.5.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-discovery.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-fileupload-1.0.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-lang-1.0.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-logging-1.0.2.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/commons-logging.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/gnu.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/gnujaxp.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/itext-1.00.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jakarta-oro-2.0.6.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/javassist-2.5.1.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jaxrpc-api.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jaxrpc-impl.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jaxrpc-spi.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jaxrpc.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jCharts-0.6.0.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jcommon-0.9.1.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jconn2.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/jfreechart-0.9.16.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/junit.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/log4j-1.2.8.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/mail.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/mysql-connector-java-3.0.14-production-bin.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/ognl-2.6.3.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/poi-2.5-final-20040302.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/saaj-impl.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/saaj.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/servlet.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/servletx.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/tapestry-3.0.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/tapestry-contrib-3.0.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/velocity-dep-1.4.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/wsdl4j.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/xercesImpl.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/xercesSamples.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/xml-apis.jar], [C:\oc4j_extended\j2ee\home\default-web-app\WEB-INF\lib/xmlParserAPIs.jar]]]: PromoPage

This is OGNL syntax to reference a static field. Read up on OGNL
syntax from www.ognl.org.
OGNL expressions in pages are implicitly relative to the page, so
anything you can get from your page class you can get directly with an
OGNL expression (except note the syntax for static fields as above).
