To determine if this issue affects your system, you can open the browser JavaScript console and look for the following error message:
Uncaught TypeError: Cannot read property 'offsetWidth' of null
If you see this error, you can easily work around it by adding a delay attribute to the tutorial element step.
...
If the 'Next' button is not enabled and the error described above is shown, simply add delayBeforeNextItem attribute to the element, specifying a delay in milliseconds. For example:
Virtualdatacenter's element
| Code Block | ||
|---|---|---|
| ||
{
"element": "#virtualdatacenters\\.tab",
"intro": "In the <strong>Virtual datacenter</strong> section, you will manage all your virtual infrastructure. Let's begin by clicking this icon<br><br><span style='color: orange'><strong>Action needed:</strong></span><br><i>Click the <strong>'Virtual datacenters'</strong> icon to continue</i>",
"position": "bottom",
"actionType": "onclick",
"blockPrevious": true,
"delayBeforeNextItem": 1000
}, |
This will be enough to resolve the issue.
It is up to you specify a suitable delay value depending on the screen and tutorial step, but it would be better to set higher delays than lower ones in order to avoid problems.
