jsf 2 - After showing / hiding a JSF element with AJAX how to hide the triggering element? -


i followed intructions given balusc in [this answer][1]

[1]: jsf , f:ajax hiding/showing div , worked. want hide element when command button pressed , element id="incorrectquestion" shown. did in example. have tried lot of combinations couldn't hide command button.

            <h:panelgroup rendered="#{not answerresultbean.showincorrectquestions}">                 <div id="logindiv" style="width: 400px; text-align: left;">                     <center>                         <f:ajax render="incorrectquestions">                             <br />                             <h:commandbutton value="#{strings.failedquestions}"                                 action="#{answerresultbean.setshowincorrectquestions(true)}" />                             <br />                             <br />                         </f:ajax>                     </center>                 </div>             </h:panelgroup>             <h:panelgroup id="incorrectquestions">                 <h:panelgroup rendered="#{answerresultbean.showincorrectquestions}">                     <div id="logindiv" style="width: 400px; text-align: left;">             ...

just put <h:panelgroup> containing button inside <h:panelgroup id="incorrectquestions"> well. way updated on ajax request , rendered condition cause hidden.

by way, try keep code dry. you've there quite code duplication. 

<h:panelgroup layout="block" id="logindiv" style="width: 400px; text-align: left;">     <h:commandbutton value="#{strings.failedquestions}"         action="#{answerresultbean.setshowincorrectquestions(true)}"         style="text-align: center; margin: 10px;"         rendered="#{not answerresultbean.showincorrectquestions}">         <f:ajax render="logindiv">     </h:commandbutton>     <h:panelgroup rendered="#{answerresultbean.showincorrectquestions}">         ...     </h:panelgroup> </h:panelgroup>

note <h:panelgroup layout="block"> generates <div>. way there's no need <h:panelgroup><div>.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
