jsf - How to perform commandLink's action method before filedownload in commandLink? -


codes:

<p:dialog header="downloads" widgetvar="hwdialog" modal="true"     showeffect="fade" hideeffect="fade" resizable="false"     appendto="@(body)" width="700" height="500" position="center center">      <p:ajax event="close" listener="#{mb.selectedreset()}"         update="@([id$=hwtable])" />      <h:form id="dlg_form">         <p:datatable id="dlg_hwtable" var="std"             value="#{mb.list}"             paginator="true" rows="10" rowkey="#{std.id}"             rowsperpagetemplate="5,10,15" rowindexvar="count">                <p:column headertext="file">                 <p:commandlink ajax="false" value="download"                     action="#{mb.preparefordownload(std)}">                     <p:filedownload value="#{mb.file}" />                 </p:commandlink>             </p:column>          </p:datatable>     </h:form> </p:dialog>

file null at first click in p:filedownload.then dialog closes unexpectedly.unexpectedly because close event doesn't work when dialog closed.but re-opening dialog , clicking link again.works downloading previous file.so filedownload performed before commandlink's action method.how can solve problem?

you need use actionlistener prepare file stream p:filedownload, because action method gets triggered after downloading logic executes.
fix dissappearing dialog - happening because without file download request resulted in non-ajaxical post navigation, resets page dom initial state.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
