FirePartialAction event parameter

Question

Hi, I'm a newbie, Thanks for your patience ...
I have a custom create rec page, there is an Item (SupplierCode) poplist with a firePartialAction, event name is "hoho", parameters I have defined "parm1" with value ${oa.CreateDetailVO1.SupplierCode}
In my Controller, processFormRequest I have the following code... just to see what I got from the parameter value,
if ("hoho".equals(pageContext.getParameter(EVENT_PARAM)))
String parmValue = pageContext.getParameter("parm1");
System.out.println("got parameter from firing event:"+parmValue);
When I run this page, the poplist is on the blank value, when I select a value 'A', it fire "hoho", but the parameter print out in the System.out.println msg is null, when I change the value to 'B', the "hoho" got fire again, with parameter value print out in the msg is 'A', when I change the value to 'C', hoho got fired again with value of 'B'.
Seems like the parameter value passed back is the old value? was it suppose to pass back with the old value? or did I do something wrong?

Answer 1

In the parameters of the firePartialAction, you must be passing some parameters to get the resultant values in the CO.
In general the format is ${oa.ViewInstance.AttributeName}
For your case try using ${oa.*current*.AttributeName}
This will give you the new value.
