setRedirectURLToSearchResults() not redirecting - netsuite

Question

I an new to NetSuite, and I am having a problem. I have created a button on a form through a user event script.
The button calls a client script, which executes a saved search. The search result should be displayed to the user.
Everything is located in one file:
function userEventBeforeLoad_AddSearchButton(type, form, request){
if(type == 'view' || type == 'edit'){
form.setScript('customscript_tvg_project_search_button');
var projectid = nlapiGetFieldValue('companyname');
form.addButton("custpage_search", "KHM Search", "performSearch('" + projectid + "')");
}
}
function performSearch(projectid) {
console.log('test in client');
alert('projectid = ' + projectid);
var obj = nlapiLoadSearch(null, 'customsearch_project_cost_detail_sublist');
obj.setRedirectURLToSearchResults();
}
I created a user event script record for userEventBeforeLoad_AddSearchButton(). and a client script record for performSearch().
In the code above, the button is created and the alert is being displayed. But no redirect is happening.
When I look at the result in Firebug it looks like this:
{"result":"\/app\/common\/search\/searchresults.nl?api=T","id":5}
Any ideas why the redirect is not happening, and what to do?
Edit: My code above was stripped down to simplify. The reason I am passing projectid over is that I actually need to filter the search result, suing the following two lines:
var searchFilter = new nlobjSearchFilter('job', null, 'anyof', projectid);
obj.addFilter(searchFilter)

Answer 1

Although the documentation does state that, "This method is supported in afterSubmit user event scripts, Suitelets, and client scripts", it seems from this NS User Group post by a Netsuite Employee in reply to someone who experienced the same issue as you, that the API does not actually perform the redirection client side:
Redirection works on server side. Use window.location.assign(url) to
navigate via script in client-side.
Testing this, I can see that setRedirectURLToSearchResults does appear to correctly "load the search into the session", so adding this line afterwards should fix your problem.
window.location = '/app/common/search/searchresults.nl?api=T';

setRedirectURLToSearchResults is not working for me either, but since you are using clientscript you might want to try this:
function performSearch(projectid) {
console.log('test in client');
alert('projectid = ' + projectid);
var searchid = 'customsearch_project_cost_detail_sublist';
location = '/app/common/search/searchresults.nl?searchid=' + searchid;
}
