I'm trying to use the expected conditions function to make protractor wait for the presence of items on a page before continuing.

I have followed the example in the docs, but I am getting an error about an undefined property.

This seems to be the case when using any expected condition, not just related to the presenceOf function I am using here:

var EC = protractor.ExpectedConditions
var pixels = element.all(by.repeater('item in items'))
var pixelsLoaded = EC.presenceOf(pixels)

browser.wait(pixelsLoaded,10000)

Failed: Cannot read property 'bind' of undefined Stack: TypeError: Cannot read property 'bind' of undefined at [object Object].ExpectedConditions.presenceOf (/foo/bar/node_modules/gulp-protractor/node_modules/protractor/lib/expectedConditions.js:233:33) at Env.

• javascript
• angularjs
• webdriver
• protractor

Fixed by removing the improper call to all:

var pixels = element(by.repeater('item in items'));
