I'm still wiggling my way through the ins and outs of Lectora. The Lectora support team has been very helpful. I've discovered some things I'd like to share.
Limitations on built-in preview. Up to a certain point, the built in preview functionality works great. But once you start doing advanced techniques such as using flash to set Lectora variables, the preview will not work.
Web Server based preview. So now I've switched to previewing my content from a web server. I installed the Apache web server and send my Lectora HTML output to a folder under the htdocs on Apache. This allows me to view the content as the end-user will see it and I can catch errors earlier in the process. However, it's not a substitute for testing it out in the actually LMS. If I had to test it in the LMS every time it would take way too long.
Do you have a method for previewing that has worked well?
