jsf - How do I pass a parameter to Primefaces menuitem that shows a dialog? -

-

i have p:menubutton contains several p:menuitems. each of these items has calls method parameter on session scoped backing bean , open modal dialog depends on backing bean. p:menuitem looks this:

<p:menuitem value="..." oncomplete="dialog.show()" update=":dialog" actionlistener="#{mycontroller.createnewitem}"> </p:menuitem>

the parameter passed mycontroller.createnewitem thing depends on menuitem clicked , tried pass in 3 ways:

1) <f:setpropertyactionlistener target="#{mycontroller.newitem.property}" value="..." />

this doesn't work because modal dialog seems block f:setpropertyactionlistener. setter mycontroller.newitem.property gets called after close dialog, not enough. works if dialog not modal, need modal.

2) <f:attribute name="param" value="..." /> event.getcomponent().getattributes() returns map single element, looks some_namespace.mark_id => number, not parameter wanted pass.

3) <f:param name="param" value="..." /> read works action, not actionlistener, tried anyway. facescontext.getcurrentinstance().getexternalcontext().getrequestparametermap() contains fields on form parameters, not 1 wanted pass, guess doesn't work.

is there way i'm trying here or stuck using f:setpropertyactionlistener , non-modal dialog? thanks.

if want pass argumens , use action

<p:menuitem value="..." oncomplete="dialog.show()" update=":dialog" action="#{mycontroller.createnewitem(your parameter)}"> </p:menuitem>

where createnewitem

public void createnewitem(.....){ }

or 

public string createnewitem(.....){       return null; }

using action return null or void wont navigation...

about ajax request , <p:menuitem doing ajax implicitly under hood anyway

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
