java - PrimeFaces Tree - show different context menu when selecting multiple nodes -

-

i'm working on primefaces web app. started getting bear me.

i have tree multiple types of nodes - each own context menu. problem want able show different context menus when single node selected , when multiple are. tree's selection mode should multiple.

code:

    <!-- here should context menu when multiple nodes selected -->     <!--        <p:contextmenu for="tree"> -->     <!--            <p:menuitem value="multiple items selected"> -->     <!--            </p:menuitem> -->     <!--        </p:contextmenu> -->      <p:contextmenu for="tree" nodetype="type1">         <p:menuitem value="type 1 selected">         </p:menuitem>     </p:contextmenu>      <p:contextmenu for="tree" nodetype="type2">         <p:menuitem value="type 2 selected">         </p:menuitem>     </p:contextmenu>      <p:contextmenu for="tree" nodetype="type3">         <p:menuitem value="type 3 selected">         </p:menuitem>     </p:contextmenu>      <p:tree id="tree" value="#{treebean.root}" var="node"         selectionmode="multiple">         <p:treenode type="type1">             <h:outputtext value="#{node}" />         </p:treenode>          <p:treenode type="type2">             <h:outputtext value="#{node}" />         </p:treenode>          <p:treenode type="type3">             <h:outputtext value="#{node}" />         </p:treenode>     </p:tree>

thanks much!

i solved purely in client side changing css of menu items wanted hide.

i used single context menu both single selection , multiple hide items don't want show multiple selection. every menu item wanted hide in case of multiple selection got style="class: multiple_tree_cm;". used context menu event on tree.

example tree:

<p:tree id="tree" widgetvar="treewv">     <p:ajax event"contextmenu" onstart="updatetreecontextmenu();"/>      <p:treenode .../> </p:tree>

example context menu:

<p:contextmenu for="tree">     <p:menuitem ... styleclass="multiple_tree_cm"/> <!-- don't want show multiple selection --> </p:contextmenu>

i hide menu items adding css class multiple_tree_cm class menu items. this:

function updatetreecontextmenu(event) {     if (pf('treewv') && pf('treewv').selections && pf('treewv').selections.length === 1) {         $('.multiple_tree_cm').removeclass('disabled');     } else {         $('.multiple_tree_cm').addclass('disabled');     } }

css:

.multiple_tree_cm {} .disabled { height: 0 !important; display: none !important; }

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
