[Xerte] Re: Almost there - then Page Templates event broadcasting became inconsistent - any ideas

[Julian Tenney]

I've had some similar issues to deal with as well. I haven't looked at the file, but here is what I would think about / try and do:

Bear in mind the flow of execution. It's basically a sideways dive through the xml tree. All children are parsed, then one by one, each of their children are parsed and so on, as you know. Is it possible that your broadcast is happening before the event response is set up and ready for action (can you debug the interaction ID of the event interaction?

Secondly as the xml is being parsed, events can cause the parsing to happen out of sequence, as you can jump around before the main parse has finished.

Something to try is to put the event handler on its own interaction icon somewhere and see if that fixes things?

Alternatively force a 0 second wait before broadcasting your event? That will ensure the first parse is complete before you start jumping around, and things should be set up.

Subject: [Xerte] Almost there - then Page Templates event broadcasting became inconsistent - any ideas

I would have posted this to the xertetrans group but could not see how to attach a file to the message.

I am trying to finalise my language demonstrations and have hit some inconsistent behaviour in Page Templates.
It appears to be very similar to what was being experienced with the auto play of narration, so I am hoping that Julian or Pat may be able to throw some light on a solution to the problem. The problem Page Templates project is attached.

If you preview the project, the project runs and there is an event broadcast by the title page but the event fails to be executed. This is critical to the languaging of pages because it loads the language file.

However if you carry on to page 2 then return to page 1 the event is executed by the Title page.

Also if you take the text page and move it up the project tree so that it is page 1 then preview the project, when you move to page 2 (which is now the title page) the title page broadcasts the event and the event is then executed loading the language file.

So what have I got to do to get the event to execute correctly when the title page is the first page in the project?

For reference there are minor changes to the templates.rlt file as follows

The entry frame has its templateData property set to the languages.xml file.
An extra event "loadLang" has been added to the narrationHandlers Interaction, with a script to load in the languages.xml file.

The title.rlm and quiz.rlm file have a little extra code to allow them to function in PageTemplates and Page Wizards. There is additional code to set up language codes for the project but this all runs after the execution of the event is completed, so should have no impact on matters. Besides once the event runs everything else works like clockwork!

Any ideas that can lead to a solution will be more than welcome!

Kind regards

Johnathan
