XPages viewPanel remembering previous selection

Question

I have a viewpanel in an XPage that has its search value "Search in Search Results" set to a sessionScope variable called queryString. it is set with the following formula...

var tmpArray = new Array("");
var cTerms = 0;
if (sessionScope.SearchTourArea != null && sessionScope.SearchTourArea != "") {
    tmpArray[cTerms++] = "(Field TourArea = \"" + sessionScope.SearchTourArea + "\")";
}
if (sessionScope.SearchTourRegion != null && sessionScope.SearchTourRegion != "") {
    tmpArray[cTerms++] = "(Field TourRegion = \"" + sessionScope.SearchTourRegion + "\")";
}
qstring = tmpArray.join(" AND ").trim();
sessionScope.queryString = qstring;
return "Query = " + sessionScope.queryString

Within the view, in the "Search in search results" I use the formula;

return sessionScope.queryString;

This all works and returns the correct results, however my problem is that it seems to remember this sessionScope variable, so if I include the following code, it will open the page saying there are "34 tours found that suit your choice" when i haven't yet set the search criteria.

if (getComponent("viewPanel1").getRowCount() == 0){
 return "Sorry, we dont yet have any Tours for this combination. Please change some of your choices"
 } else {
return getComponent("viewPanel1").getRowCount() + " tours found that suit your choice"
 }

I'm at a loss. I think all i need to do is reset the sessionScope variable to "", but dont seem to be able to do it.

thanks in advance,

You don't state where sessionScope.queryString being set. Please add that information and/or confirm the code is being run again when you expect it to. — Paul Stephen Withers
I agree with what Paul said. A sessionScope variable is saved across the session so once set it will be reused unless changed. You can change to use a viewScope variable instead. — Per Henrik Lausten
Sure, once the user selects the field values (activity, sub activity etc). They then click on a button that performs a partial refresh on a computed field that works out/displays the formula and the view needs to be refreshed. The code works perfectly whenever it is run, the only part I am struggling with is that it the view seems to retain the number of results, even if it isn't showing them. I have tried the viewScope, but it wasnt doing it as well as i wanted. Is there a way to clear the sessionScope on opening an XPage - and the resulting view results? thanks again. — smacca01
You can reset sessionScope variable in beforePageLoad event. — Knut Herrmann
Hi, thanks, I tried that but it didn't seem to effect the view count at all. I used sessionScope.queryString ="". Is that correct? Thanks again. — smacca01
