Error loading pages after latest update (linked to caching)

[dredlong]

After updating to the latest version, the pages where I'm using this plugin started throwing the error Call to a member function path() on null. It points to line 166 of the file TableImporterShortcode.php:

$path = $this->grav['shortcode']->getPage()->path();

Clearing the cache temporarily fixes the problem and lets the page load once, but then errors on reload. Setting cache_enable: false on the page prevents the error but I'd prefer to let the pages be cached if the issue can be addressed another way.
