thx for this hint. "You must ensure that the parameters are available not only when the page is rendered, but also when it is sub- mittedIf the arguments can not be resolved when the page is submitted the action method will be called with null arguments" --> Stateful bean, right? I did read the chapter and adapted my program according to it. I didn't had any luck. I changed my Project so it looks same like the booking example. I dont see any difference in my code the the booking example. I am quite frustrated because i don't get any feedback from the system and I am trying all kind of combinations since 3 days now with no luck. I have a list of results If the user clicks on an author from the list the page is redisplay according to the parameter passed in the function call searchByCreator(); | | <h:form id="searchForm"> | <h:inputText id="value" required="false" value="#{searcher.searchString}" style=" width : 300px; "/> | <h:commandButton id="search" value="search" | action="#{searcher.search}" style="width : 50px; "/> | </h:form> | | | <h:dataTable var="resultElem" value="#{searchResult}"> | <h:column> | <!-- Creator --> | <h:form styleClass="subText" style="margin:auto;padding:auto; /*just for the IE*/"> | <ui:repeat var="a" value="#{resultElem.doc.creator}" > | <h:commandLink value="[#{a}]," action="#{searcher.searchByCreator(a)}" /> | </ui:repeat> | </h:form> | </h:column> | </h:dataTable> | | @Stateful | @Name("searcher") | public class SearchBean implements Search, Serializable { | | @DataModel | private List<SearchResult> searchResult; | | public void searchByCreator(String creator){ | .... | } | ... | | @Destroy | @Remove | public void destroy() {} | | if I use h:commandLink my function is never called the page is just rerendered If I user s:link the function gets called but the parameter is empty! If i put the h:command link outside the ui:repeat this makes no difference the result is the same like above. If I use the in second loop a h:dataTable i have the same result as above simplified system: If i make a function call outside the DataTable id doesn't work always | inside the search form | <h:form id="searchForm"> | <h:inputText id="value" required="false" value="#{searcher.searchString}" style=" width : 300px; "/> | <h:commandButton id="search" value="search" | action="#{searcher.search}" style="width : 50px; "/> | <h:commandLink styleClass="subText" value="#{searcher.searchString}," action="#{searcher.searchByKeyword(searcher.searchString)}" /> | Does work | </h:form> | Two Forms | <h:form id="searchForm"> | <h:inputText id="value" required="false" value="#{searcher.searchString}" style=" width : 300px; "/> | <h:commandButton id="search" value="search" | action="#{searcher.search}" style="width : 50px; "/> | <h:commandLink styleClass="subText" value="#{searcher.searchString}," | </h:form> | | <h:form> | action="#{searcher.searchByKeyword(searcher.searchString)}" /> | don't work | </h:form> | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4121650#...
