The first is an example of using the init() call back method on a ViewController. It pulls the request parameter using the implicit el map, #{param}. There are a bunch of ways to handle this. You can also access params from the faces context. http://svn.apache.org/viewvc/shale/trunk/shale-apps/shale-clay-usecases/src/main/java/org/apache/shale/usecases/symbols/RegistrationForm.java?view=markup This next example uses an action binding and managed bean setter injection. The changeTab method is bound to an commandLink, [EMAIL PROTECTED] The command link has a tabIndex parameter that is extracted by delivering a managed bean. QueryParam paramObj = (QueryParam) getBean("queryParam"); String tabIndex = paramObj.getTabIndex(); The "queryParam" bean is populated with the request parameters and also cached in request scope. <managed-bean> <description> This class simulates the classic Struts FormBean where request parameters are populated in a POJO object. </description> <managed-bean-name>queryParam</managed-bean-name> <managed-bean-class> org.apache.shale.usecases.rolodex.QueryParam </managed-bean-class> <managed-bean-scope>request</managed-bean-scope> <managed-property> <property-name>tabIndex</property-name> <value>#{param.tabIndex}</value> </managed-property> <managed-property> <property-name>selectedName</property-name> <value>#{param.selectedName}</value> </managed-property> </managed-bean> http://svn.apache.org/viewvc/shale/trunk/shale-apps/shale-clay-usecases/src/main/java/org/apache/shale/usecases/rolodex/Rolodex.java?revision=419348&view=markup Gary > > stephan > > 2006/7/13, stephan opitz : > > first - is it possible to log all submited params in to file or output > > of servers log? > > > > second: > > how i built input sides with command button is no problem... > > > > but if i have a commandlink, which should go to a side and has an > > hidden value, from which the sides generate output :-/ > > > > > > > > > > > value="#{categories.showCats}" /> > > > > > > > > > > > value="category_id" /> > > > value="#{node.identifier}" /> > > > > > > > > > > > > > value="#{node.description}" /> > > > value="nodeFolder" /> > > > > > > > > > > the commandlink links to another side... the method showCats will be > > called, but how i also submit the category_id and ist it usefull to > > use some kind of the new functions like init() to prebuilt output data > > from db for the given category_id > > > > stephan > >
