Get updated value from bean through JavaScript in JSF -


i have context menu in itemcomp.xhtml , if click on item in context menu action itemdisplay.refreshitems called , on complete of action javascript function showpanel() called

itemcomp.xhtml

<rich:contextmenu disabledefaultmenu="true" event="oncontextmenu" submitmode="ajax">     <rich:menuitem disabled="true" style="color:black; font-weight:bold;" value="items"/>     <rich:menuseparator/>      <c:foreach items="#{itemdisplay.componenttypemap.keyset}" var="itemvalue">         <rich:menuitem value="#{itemvalue}"                        rendered="#{(itemvalue == 'bags report') or                                    (itemvalue == 'chairs report') or                                    (itemvalue == 'tables report')}"                        action="#{itemdisplay.refreshitems}"                        oncomplete="showpanel( '#{itemvalue}','#{item.id}')">         </rich:menuitem>     </c:foreach> </rich:contextmenu>

in refreshitems() of itemdisplaybean.java, setting variables true.

itemdisplaybean.java

private boolean availablebags = false;

public boolean getavailablebags() {     return this.availablebags; }  public void setavailablebags(boolean availablebags) {     this.availablebags = availablebags; } private boolean availablebags = false;  public boolean getavailablebags() {     return this.availablebags; }  public void setavailablebags(boolean availablebags) {     this.availablebags = availablebags; } private boolean availablechairs = false;  public boolean getavailablechairs() {     return this.availablechairs; }  public void setavailablechairs(boolean availablechairs) {     this.availablechairs = availablechairs; } private boolean availabletables = false;  public boolean getavailabletables() {     return this.availabletables; }  public void setavailabletables(boolean availabletables) {     this.availabletables = availabletables; }  public string refreshitems() {     setavailablebags(true);     setavailablechairs(true);     setavailabletables(true); }

and in itemdisplay.xhtml, have javascript function showpanel() follows.

function showpanel(item, itemid) {      if (item == 'bags report') {         if (#{itemdisplay.availablebags})             richfaces.showmodalpanel('bags');         else             alert('no bags found');     } else if (item == 'chairs report') {         if (#{itemdisplay.availablechairs})             richfaces.showmodalpanel('chairs');         else             alert('no chairs found');     } else if (item == 'tables report') {         if (#{itemdisplay.availabletables})             richfaces.showmodalpanel('tables');         else             alert('no tables found');     } }

and problem here -- in javascript function, not getting updated backing bean values, hence availablebags ( if( #{itemdisplay.availablebags} ))is false (even though set true in backing bean), , panel not shown. if refresh page updated value backing bean ( if( #{itemdisplay.availablebags} ) true , panel shown.any 1 can me why getting updated value refreshing page.

as pointed out el expressions evaluated when page renders , become static text.

you can use @data, e.g.:

<rich:menuitem data="#{itemdisplay.availablebags}"      oncomplete="showpanel('#{itemvalue}', event.data)" … >

event.data contain current value of property (you can point object).

edit: in richfaces 3.x js parameter data

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
