Searching LOV is not invoking any method

Question

Hello JHeadstart team:
I have the following behaviour with my LOVs generated from JHeadstart (10.1.2)
The "Go" button seems to not invoke anything, just give back the same page, not doing any filter.
By watching the log window in JDeveloper, seems like no event is invoked.
Also, I don't see in the generated lov.uix page an event called lovFilter under handlers (should I have one?)
When the page is invoked from the parent page, I have the following log, and the advancedSearch is being invoked giving me the filter, if I typed something before clicking the flashlight:
12:01:56 DEBUG (JhsActionServlet) -Setting current HttpServletRequest on jhsUserRoles wrapper object on session to allow EL access to request.isUserInRolefunction

But nothing happens when clicking "Go". Is it a bug? Do I have any workaround?

Answer 1

Here goes my workaround. JHeadstart Team, please check if what I'm doing is right. If yes, I believe this is an important correction for future releases:
Reason:
The LOV page generated has in the <listOfValues> tag the attribute searchAreaMode="filter".
The onLovFilter event has the code:
String searchAreaMode = request.getParameter(SEARCH_AREA_MODE);
if ("advanced".equals(searchAreaMode))
onAdvancedSearch(daContext);
else if ("simple".equals(searchAreaMode))
onQuickSearch(daContext);
else
// if we get here, we are not yet in the LOV page, the user
// has invoked the page through clicking on the lov icon.
// we must clear the search text so it is not displayed as search
// criterium in the lov (searchAttribute is already empty when
// clicking the lov icon)
// And onQuickSearch should only execute the query if iterator
// is not inf find mode. To signal to the onQuickSearch method that
// this check is needed and to clear the search text, we set a
// request attribute
request.setAttribute(LOV_CHECK_FIND_MODE, "true");
mLog.debug("Lov icon clicked, clear searchText in searchBean");
onQuickSearch(daContext);
But this code is setting the LOV_CHECK_FIND_MODE to true when searchArea = "filter", making the onQuickSearch event to set the searchText to null
I overriden the whole event adding also the
else if ("filter".equals(searchAreaMode))
onQuickSearch(daContext);
and now is working fine.
In my previous post I mentioned that also the attribute was wrong, but this was my mistake in the ApplicationStructure file.
