angularjs - Protractor test throws 'element invalid state' exception as soon as I add 'expect' assertion -

-

i have protractor test passes - until add 'expect' assertion end of it. that, 'invalidelementstateerror: invalid element state'. i'm aware protractor asynchronous, building queue of promises , reason barfs @ assertion - have no idea why. 

describe('compose', function() {      it('should send message', function() {         browser.ignoresynchronization = true;         browser.findelement(by.id('compose-link')).click();         browser.sleep(2000);          //select recipient              var el = element(by.name('input_to'));         el.click();         el.sendkeys('a');         //wait server autofill...         browser.sleep(500);         el.sendkeys(protractor.key.enter);          //snip...         //keep clicking buttons, filling out fields etc...         //end snip          //select category         el = element(by.id('section-3')).element(by.css('.secret'));         el.sendkeys('cl')           el = element(by.id('send-now'));         el.click();         //wait confirmation message         browser.sleep(1000);          expect(element(by.id('confirm-sent')).gettext()).toequal('task sent!');     }); });

btw, ignoresynchronization set true because otherwise browser fails sync apparently due server autofill on elements. can turn ignoresync off after fields makes no difference - still need browser.sleep everywhere make test work, leave set true.

if element appearing on click() action of element wait until click() function returns promise , try checking element visible using wait() function. text of element. using wait() function more suitable use sleep(). here's snippet of functionality - 

var ele = element(by.id('confirm-sent'); el.click().then(function(){     browser.wait(protractor.expectedconditions.visibilityof(ele), 10000)     .then(function(){         expect(ele.gettext()).toequal('task sent!');     }); });

hope helps.
