i have no idea, why should not work. want every time changes toolbox value show additional information form toolbox

when update part of view have specify id of element present in dom. panel trying update not present in dom, in case form.toolbox evaluates true. when false cant updated , not added view. can solve problem is, wrap panel inside element , update element. work because wrapper-element present.

so try following part of panel:

<h:panelgroup id="toolboxoptions">     <p:panel id="toolboxoptionspanel" rendered="#{form.toolbox}">     ....     </p:panel> </h:panelgroup>

have @ answer of following question further explanation: jsf + primefaces: `update` attribute not update component
