How can a Caliburn.Micro sub menuitem click call an action on the containing view's viewmodel? -

-

i have top level menu in shellview , when selecting sub menuitem, call following method on shellviewmodel (a conductor.collection.allactive).

    public void selectserver(string pservername)     {         mdefaultclaimserver = pservername;     }

the following not work no method gets called (i have tried various signatures , action parameters) -

    <menu name="menu1" dockpanel.dock="top">         <menuitem header="select server" name="claimservers">             <menuitem.itemtemplate>                 <datatemplate>                     <!-- need else show class name -->                     <textblock text="{binding displayname}">                         <contentcontrol cal:message.attach="[event click] = [action txtester.shellviewmodel.selectserver($text)]"/>                     </textblock>                 </datatemplate>             </menuitem.itemtemplate>         </menuitem>     </menu>

the following call shellviewmodel selectserver method null text of clicked sub menuitem (i tried many other signatures , action parameters) -

    <menu name="menu1" dockpanel.dock="top">         <menuitem header="select server" name="claimservers" cal:message.attach="selectserver($this.text)">             <menuitem.itemtemplate>                 <datatemplate>                     <!-- need else show class name -->                     <textblock text="{binding displayname}" />                 </datatemplate>             </menuitem.itemtemplate>         </menuitem>     </menu>

i've been struggling long time , can't figure out. can suggest proper combination can pass header text of sub menuitem shellviewmodel selectserver method?

i got trying working, per post rob eisenberg describing "special trick text bound submenus" here - http://caliburnmicro.codeplex.com/discussions/287228

i still love know how trying standard ootb logic if has suggestions, able understand cm better.

basically added bootstrapper configure() overide -

        messagebinder.specialvalues.add("$originalsourcecontext", context =>         {             var args = context.eventargs routedeventargs;             if (args == null)                 return null;              var fe = args.originalsource frameworkelement;             if (fe == null)                 return null;              return fe.datacontext;         });

and added xaml -

        <menuitem header="_select server" name="claimservers" cal:message.attach="selectserver($originalsourcecontext)" />

and passed header text of sub menuitem wanted.

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...
