Dont understand you dan ?
The backing bean is being invoked based on the refresh, I can see the
getMethods getting invoked , however, nothing is updated at the client side.
I have debug at the backing end to show me what is being returned to the
client.
I see the actual value being returned
such as
public String getVar1Value() {
if ( cachedRowSetListener == null ) {
rtn="initialvalue";
} else {
.....do some work ....
rtn = blablbal
}
logger.debug("The value being returned to client is "+rtn);
return rtn;
}
I just sent the example to simplify what I was doing.
Within the logger line I see the value changes. I also see the JSON response
to the client within firebug, but nothing happens on screen. And when I do
any alerts in my code in the client to check the values of the local dom
object ( ie the hidden fields/text fields whatever ) they still have their
old value.
