Hi,

Sorry, UI actions do a page reload when you do current.update() (save your changes).

What is the issue you are trying to solve?

Hi Chuck,

While submiting a change, I need to display an error message(should not do the current.update())   if there is no tasks under particular change request.

Now I'm able to display the error message , but it's disappearing with in 1 second and page is reloading.

I want to show that error message until user closes it.

Thanks

Bala

You can achieve by using client functionality in UI actions

here is the sample script that check if there are any test cases under a test plan (current)

You can you the same logic for checking if change tasks are present

Go through this article

Client & Server Code in One UI Action - ServiceNow Guru

which explains you how the client side functionality works

function test_case()
{


   var test = new GlideRecord('tm_test_case_instance');
       test.addQuery('tm_test_plan', g_form.getUniqueValue());
       test.addQuery('active',true);
       test.query();
       if(test.next())
       {
           gsftSubmit(null, g_form.getFormElement(), 'plan_approval');
       }
       
       else
       {
           alert('Atlease one test case should be added to the list');
           return false;
       }
 
 
 
 
}
if(typeof window =='undefined'){
 updateChange();
}
function updateChange(){
 
 current.state = '3';
 current.update();
action.setRedirectURL(current);
}
