Category pages should render without error #25
Description
Requesting an E-Commerce category page currently yields unexpected results.
A generic category page like http://localhost/categories/generic yields a couple of exceptions and renders errors in a couple of regions on the page.
A category page for a specific category, like http://localhost/categories/jeans will not throw errors, but it will not render the same like http://localhost/c/jeans (the latter is handled by the E-Commerce controller). For example, it shows the presentation (aggregated/split) facet.
Now, usually a visitor does not request those system pages, but since they are real pages, you could. Also, when using the language selector DXA will think you are on the category page, and link to the the /categories/ URLs mentioned above.
