jsf - primefaces panelgrid update from datatable -


i getting "cannot find component identifier "contentform:tabview:form:addressdialogpanel" referenced "contentform:tabview:form:addressbooktable" " error. how can update panelgrid inside widget?

<h:form id="form">  <p:datatable id="addressbooktable">  <p:ajax event="rowselect" listener="#{addressbookcontroller.onrowselect}"                    update="contentform:tabview:form:addressdialogpanel" oncomplete="addressdialog.show()" /> </p:datatable>  <p:dialog id="addressdialogid" widgetvar="addressdialog">   <h:panelgrid id="addressdialogpanel" columns="2" cellpadding="4">   </h:panelgrid> </p:dialog>  </h:form>

the main problem giving wrong client id of component's. p:tabview component not form. when define h:form, generates standart html form element. , when submit page jsf uses post submit data backing bean. nesting them going occur lot's of issues don't expect. should seperate forms sections sideform or searchform or etc.

you should detect correct client id of component when try update it. can browser's developer settings(press f12 chrome). select component magnifier button , give id update property. here:

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
