Always value in pure research, but just to be a negative Nellie, I've real doubts about a feature like this actually being used, even if the technical issues are addressed.
Authorware had "jumpfile", which seamlessly segued between files.It was used if you had a router style architecture.
Don't remember anyone asking for the ability to jump to a specific page.That sounds like a glossary or definition type structure requirement and there's easier ways to accomplish those.And without the ability to return to the same place in the calling module (Call and Return), I don't see huge numbers of folks using it.
But like I said, futzing around is a great way to stumble across other nuggets.:-)

According to my Xerte desktop installation it generates a linkID and not a pageID 
phew you had me worried there for a minute :-)

I know you have referred to "deep linking" before but I was never sure what you meant.

The idea here was to create a link using a value known to the learning object author.
It was just an experiment. Maybe if it works without the delay in XOT then it would be more acceptable.

I can shorten the delay in Xerte but in the absence of a means of knowing when the page array has been fully populated it will always be guess work as to how short the delay can be.

Kind regards

No, the wizard automatically produces a pageID in the xml – you’ll have seen it I’m sure. The intention for this was to facilitate deep linking, i.e. ?pageID=321234524
 But when Pat and I tried to get it to work nicely we couldn’t and parked it. It may well be we hit the same issue you have hit: the need for the delay, which I don’t think is acceptable to the end user.

 The javascript routine used matches a name to data, so you could just as easily use ?name=titlePage as you could ?pageID=titlePage 
 The problem with using name is that the page name is more likely to be "Title Page" and the use of spaces might cause a problem.
 It was never intended that this should be an alternative routing internally within a learning object to another page in that learning object. It was only intended to be a means of opening a different learning object, which you can do already using a URL. The only difference here was that someone on one of the postings was lamenting the inability to open a new learning object at a specific page.
 The version for XOT would have to use the extXML which, from memory, did not suffer the need for a delay before it could be used. But I am quite happy to leave it out of this release as once people were happy it would work OK then it could be added later.
 I need a little time to finish the XOT demo version anyway and right now I am focusing on an update to the scenario page to make it easier to implement scenarios like the Farmer, the Goose, the Fox and the Bag of Grain on one side of the river. 
 Kind regards

The need for that delay may well be why we decided to leave it last time. It’s disorienting to see the page for that long and then suddenly be moved on. Let’s leave this for another time.

 The delay is because I have had to put a timer in to give Xerte the time to build the rootIcon.pages array - it's a bit of guess work as to how long I need to give it. It would be nice if the onInit event didn't fire until the array had completed being built, then I could remove the timer and the delay would be reduced to the minimum required.
 In XOT you use a different array so I think the time delay will be insignificant as if I recall correctly the array was already fully available.
 I'll run some further tests in XOT now that I have the javascript sorted out and then post something for you to try out.
 Kind regards

Working fine here (although with a noticeable lag, first page is shown and after 1 second the menu page is opened)

Hello Everyone, I have been working (between beta version stuff) on a means of making it possible to open a Xerte project at a specific page, rather than always have them open at the title page.
 Attached is a simple 3 page desktop Xerte project as a proof of concept.
 Do not open it in Xerte (at least until you have finished testing it!) If you publish the project, in Xerte, your local copy of rloObject.js will overwrite the one in the project and the code that supports the redirection will be lost.
 Would you mind unzipping it and then opening index.htm in a web browser - not Xerte.
 For it to work you will need to set up the folder in which you place it as a trusted location in the Flash player settings (otherwise javascript calls will not work).
 It should open at a title page. 
Then add to the url in your browser  
?pageID=menu and press enter to reload the page.
 After a short delay the project should redirect from the title page to the menu page. 
I have tested this in Firefox, IE8, and Opera.  
If anyone has other browsers at their disposal I would be keen to know if the redirection works. e.g. Chrome, Safari, 
Should you examine the project the key stuff that makes it work is a function at the end of rlsObject.js and some code running off the onInitHandler interaction in the entry frame. Because rootIcon.pages.length has not finished being built when the onInit event fires I have added a timer to create a delay to allow time for the array to be built - hence the delay before redirection takes place.
 Should this prove reliable in your testing I believe the same approach should be applicable to XOT (albeit using a different array to source the page information)
 Kind regards
