nullpointerexception - What might be the reason for JSF/MyFaces to lose its FacesContext? -


i have webapplication based on jsf(2.1.17) myfaces /primefaces + omnifaces on 8.0.0.9

most of time works ok, following exception:

java.lang.nullpointerexception         @ org.apache.myfaces.shared.context.flash.flashimpl.iskeepmessages(flashimpl.java:388)         @ org.apache.myfaces.shared.context.flash.flashimpl._savemessages(flashimpl.java:668)         @ org.apache.myfaces.shared.context.flash.flashimpl.dopostphaseactions(flashimpl.java:269)         @ org.apache.myfaces.lifecycle.lifecycleimpl.render(lifecycleimpl.java:254)         @ javax.faces.webapp.facesservlet.service(facesservlet.java:199)         @ com.ibm.ws.webcontainer.servlet.servletwrapper.service(servletwrapper.java:1230)         @ com.ibm.ws.webcontainer.servlet.servletwrapper.handlerequest(servletwrapper.java:779)         @ com.ibm.ws.webcontainer.servlet.servletwrapper.handlerequest(servletwrapper.java:478)         @ com.ibm.ws.webcontainer.servlet.servletwrapperimpl.handlerequest(servletwrapperimpl.java:178)         @ com.ibm.ws.webcontainer.filter.webappfilterchain.invoketarget(webappfilterchain.java:136)         @ com.ibm.ws.webcontainer.filter.webappfilterchain.dofilter(webappfilterchain.java:97)         @ org.omnifaces.filter.facesexceptionfilter.dofilter(facesexceptionfilter.java:56)         @ org.omnifaces.filter.httpfilter.dofilter(httpfilter.java:77)         @ com.ibm.ws.webcontainer.filter.filterinstancewrapper.dofilter(filterinstancewrapper.java:195)         @ com.ibm.ws.webcontainer.filter.webappfilterchain.dofilter(webappfilterchain.java:91)

// ... more filters ...

when looking @ flashimpl line388 if find:

@override public boolean iskeepmessages() {     facescontext facescontext = facescontext.getcurrentinstance();     externalcontext externalcontext = facescontext.getexternalcontext(); //<-- line 388     map<string, object> requestmap = externalcontext.getrequestmap();     boolean keepmessages = (boolean) requestmap.get(flash_keep_messages);      return (keepmessages == null ? boolean.false : keepmessages); }

so looks there no facescontext. although (again looking @ code) should created in facesservlet.service further call stack.

one of filters have registered logs time used in different phases of jsf lifecycle, , complains phase render_response started, although running.

logging suggesting in current request requested page not found , therefor apropriate error page requested.

all might happen during ajax request not sure.

any ideas might causing problem?

i found this bugreport couldn't find reference getrequestdispatcher doesn't seem apply.

i found question: null pointer exception in flashimpl.java in ibm jsf might duplicate since have more (possibly relevant) information might or might not apply other question thought better create new one.
