[Xerte] Re: Glossary, video, visibility issues in HTML5 preview and deployment

Thanks for the quick replies. Attached is the data.xml file for the LO. Reducing the number of entries does allow the resource to load but doesn’t seem to affect the other issues. I’ve been moving between machines, one Win7 but using MAXOS and the other Win8.1 using a local XAMPP setup, for development. I don't have any knowledge of xml so am a bit at a loss for troubleshooting.

I am in the final phases of completing a LO in XOT 2.0 and I have run across an array of issues that I am hoping someone may be able to help me solve. I moved this resource from Captivate to Xerte and would hate to have to move it back at this point.


A bit of background first: The resource is for language learners who will not be connected to the internet so the final deployment is planned to be via USB flash memory. The includes a large glossary of terms (100+ terms), video (mp4) and audio (mp3). As it will be on flash, higher quality video and audio is preferred. HTML 5 is also preferred as we may deploy online at a later date and want users with Apple devices, such as iPads, to be able to access the resource.


At the start of the project I added the text and images and all appeared to preview fine. I exported a SCORM 2004 deployment to demonstrate the resource and it too ran fine in Moodle 2.2. I then added the audio and all still seemed alright. 


Adding the video, however, brought about some unwelcome changes. The video will be embedded in multiple places as it is used for different parts of the instruction. The video would play fine once but afterwards it would not load (nor would it load on subsequent pages with the same video). The video is also on a quiz interaction page, on which it appears to be embedded twice (two video players appear stacked on top of each other). 


At some time during this, the main template disappeared during previews. Page content does appear, and unticking the visibility:hidden box during debug in browser brings the template back. I believe I have seen this posted previously so I am not focusing on this issue here but perhaps it is relevant. 


Finally, when I expanded the glossary (which also initially played fine) to include all terms, it seemed to break the LO. When I try to preview the LO, the template does not appear nor does the page content. Changing the visibility in browser debug does bring back the template but not the navigation buttons or the page content. Also, when I tried to export the LO it no longer sends the files to a zip; rather, it creates an empty zip file and puts the files in the USER-FILES folder for the project.


One other point to further confuse is that if I change the default engine to Flash, much of the resource shows up properly.


Any ideas? I was hoping to demo this for final vetting in two weeks but in this state it is unusable.


Thanks for any help that can be provided. I can attach xml or other files if that is required for further digging.
