[ https://issues.jboss.org/browse/JBSEAM-4800?page=com.atlassian.jira.plugi... ] Samuel Mendenhall updated JBSEAM-4800: -------------------------------------- Description: When clicking on an s:link after a node has been taken down, the exception below is thrown. The s:link will only work if the page is refreshed first so it is served by the new JBoss instance, but that negates transparent failover. Method of reproducing: * Two EAP 5.1 nodes fronted with mod_jk. No firewall, sticky sessions + session replication definitely enabled. * JBDS Seam generated ear + a simple @Clustered EJB3 which has a method that takes a parameter and prints the EL parametrized text (I don't think EL parametrization is relevant here) * Click on the s:link on the page, it invokes fine, go back in the browser. Shutdown the active JBoss instance. Click the s:link again which is redirected to the 2nd JBoss now and receive: 14:17:42,995 ERROR [Exceptions] handled and logged exception java.lang.IllegalStateException: Unable to read view /home.xhtml to execute action "#{someComponent.printText('Hello World')}" at org.jboss.seam.navigation.SafeActions.isActionSafe(SafeActions.java:67) at org.jboss.seam.navigation.Pages.callAction(Pages.java:699) at org.jboss.seam.navigation.Pages.preRender(Pages.java:331) at org.jboss.seam.jsf.SeamPhaseListener.preRenderPage(SeamPhaseListener.java:561) at org.jboss.seam.jsf.SeamPhaseListener.beforeRenderResponse(SeamPhaseListener.java:472) at org.jboss.seam.jsf.SeamPhaseListener.beforeServletPhase(SeamPhaseListener.java:148) at org.jboss.seam.jsf.SeamPhaseListener.beforePhase(SeamPhaseListener.java:118) SafeActions.java:67 isn't so telling: =================== String viewId = id.substring(0, loc); String action = "\"#{" + id.substring(loc+1) + "}\""; InputStream is = FacesContext.getCurrentInstance().getExternalContext().getResourceAsStream(viewId); if (is==null) throw new IllegalStateException("Unable to read view " + "/" + viewId + " to execute action " + action); =================== The code says the InputStream is null on failover, so the getResourceAsStream(viewId) failed to return anything. was: When clicking on an s:link after a node has been taken down, the exception below is thrown.
