In Adobe Customer Success meeting and New Capabilities link, there is talk of Single Page Application Editor. During the Adobe Customer Success AEM 6.4 preview meeting, we couldn't get the answer to the questions related to SPA Editor. We were advised to post questions to helpx forum.
Discussion points are
Does SPA editor supports editing content for a multi route application? (In AEM 6.4 preview meeting a page was shown but multiple page routing was not shown)
Where can we get the sample application implementation (Looks like this is separate installation required), this is not available with AEM 6.4 Beta preview copy?
Does SPA editor supports to add new components in page dynamically? Any change required on SPA application to consume newly added components in page?
