ajax - PropertyNotFoundException when using bean's method's result for <h:selectBooleanCheckbox/> -


environment:

  • primefaces 5.1
  • mojarra 2.2.2
  • spring 4.0.2

current code:

i have following xhtml page:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"                 xmlns:ui="http://java.sun.com/jsf/facelets"                 xmlns:h="http://java.sun.com/jsf/html"                 xmlns:f="http://java.sun.com/jsf/core"                 xmlns:p="http://primefaces.org/ui"                 xmlns:c="http://java.sun.com/jsp/jstl/core"                 template="/web-inf/pages/main/admin.xhtml">      <ui:define name="contentbody">         <p:datatable widgetvar="weekdaytable"                      value="#{weekdaylist.countries}"                      var="ctr"                      styleclass="weekdaysmanagementdatatable">              <p:column width="100"                       sortby="#{ctr.desc}"                       headertext="#{msg['page.admin.weekday.list.country']}">                 <h:outputtext value="#{ctr.desc}" />             </p:column>              <c:foreach items="#{weekdaylist.weekdays}" var="day">                 <c:set var="open" value="#{weekdaylist.checkopen(ctr.id, day.date)}"/>                 <p:column width="20" headertext="#{utils.datetodayweek(day.date)}">                     <h:selectbooleancheckbox value="#{open}">                         <p:ajax listener="#{weekdaylist.handleday(ctr.id, day.id)}" />                     </h:selectbooleancheckbox>                 </p:column>             </c:foreach>         </p:datatable>     </ui:define> </ui:composition>

the associated bean following :

@named("weekdaylist") @scope("session") public class adminweekdaylistcontroller implements serializable {      ...      public boolean checkopen(string ctrid, date date) {         country ctr = countrydao.getbyid(ctrid);         list<weekday> list = weekdaysmap.get(ctr);          if (list == null) {             return true;         }          weekday day = new weekday();         day.setdate(date);          (weekday wd : list) {             if (wd.compareto(day) == 0) {                 return wd.isopen();             }         }         return true;     } }

i have bean maintains current page display , whole application made ajax. user on same page , content dynamically loaded.

the problem:

when reload (f5) page, seems work correctly. but, if go trought normal navigation (ajax loading), have got propertynotfoundexception...

here stack trace:

but make me think problem not come bean is, if remove #{open} value of <h:selectbooleancheckbox/> works (except checkboxes not checked way want):

<c:foreach items="#{weekdaylist.weekdays}" var="day">     <c:set var="open" value="#{weekdaylist.checkopen(ctr.id, day.date)}"/>     <p:column width="20" headertext="#{utils.datetodayweek(day.date)}">         #{open}         <h:selectbooleancheckbox value="true">             <p:ajax listener="#{weekdaylist.handleday(ctr.id, day.id)}" />         </h:selectbooleancheckbox>     </p:column> </c:foreach>

as can see keep using #{open} not inside value attibute.

questions:

what did wrong? missing something? there bug?

thanks.

so... have found "solution", , respond own question.

i added fakes getter , setter method checkopen. bean looks this:

@named("weekdaylist") @scope("session") public class adminweekdaylistcontroller implements serializable {      ...      public boolean getcheckopen() {         return true;     }      public void setcheckopen(boolean b) {     }      public boolean checkopen(string ctrid, date date) {         country ctr = countrydao.getbyid(ctrid);         list<weekday> list = weekdaysmap.get(ctr);          if (list == null) {             return true;         }          weekday day = new weekday();         day.setdate(date);          (weekday wd : list) {             if (wd.compareto(day) == 0) {                 return wd.isopen();             }         }         return true;     } }

this way jsf thinks checkopen valid (read/write) attribute, but calls checkopen(string ctrid, date date). never calls getter or setter...

if can explain this, gratefull. , if has better solution, listening.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
