jsf 2 - How to pass a value on selected row change? -


i have permanent problem, have datatable value="#{mybean.items}" var="itms", , want pass selected item bean class.

in columns, use <f:setpropertyactionlistener value="#{itms}" target="#{mybean.selectedrow}" /> pass value, want rows. how that?, , put listener?.

thank much.

what richface version using?

for richfaces 4.3.x, following example might trick:

xhtml:

<rich:extendeddatatable   id="mytable"   value="#{crudbean.rows}"   var="rowitem"   rowclasses="odd-row, even-row"   selection="#{crudbean.actionform.selection}"   rows="#{crudbean.actionform.occurrences}"   rowkeyvar="idx" >   <a4j:ajax event="selectionchange"     listener="#{crudbean.actionform.selectionlistener}"     immediate="true" />   <rich:column width="100px" styleclass="#{rowitem.classname}">     ...stuff...   </rich:column>   <rich:column width="173px" styleclass="#{rowitem.classname}">     ...stuff...   </rich:column> </rich:extendeddatatable>

the following code made sure got fired on row selection change:

<a4j:ajax event="selectionchange"   listener="#{crudbean.actionform.selectionlistener}"   immediate="true" />

the bean:

public void selectionlistener(ajaxbehaviorevent event) {   uiextendeddatatable currentdatatable = (uiextendeddatatable) event.getcomponent();   object originalkey = currentdatatable.getrowkey();    // debug log statement   log.debug("selectionlistener() - rowkey = {} ", originalkey);   // debug log statement   if (log.isdebugenabled()) {     log.debug("\n selectionlistener() - rowindex = {}", currentdatatable.getrowindex());   }   if (currentdatatable.isrowavailable()) {     // selectionitems.add(datatable.getrowdata());     idatarow rowvalue = transform((idatagridrow)currentdatatable.getrowdata());     changeactiverow(rowvalue);   } }

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.
