hello,
example:
use [1] to generate a demo application with facelets (option 2).
change the id of the panelGrid
from
<h:panelGrid id="grid" columns="2">
to
<h:panelGrid id="#{helloWorldBacking.myId}" columns="2">
and add
public String getMyId() {
return "myID";
}
to the HelloWorldBacking class.
have a look at the rendered html and you will find:
<table id="form:myID">
regards,
gerhard
