[Xerte-dev] Re: Xerte editor closes if you add a setup script to the Learning Object icon

Mon Feb 27 12:36:04 GMT 2012

But in thepreloader the xml is laoded. So it must know what file to load in there somewhere.

OK I can see in MainPreloader the jumpFile(url) method, and its reference to

this.contentXML._url

but if I try in xerte to

debug("contentXML = " + _level0.contentXML._url);

I still get contentXML = undefined.

If I try

debug("contentXML = " + contentXML._url);

I get

contentXML = file://C:\Xerte2\XMLEngine.swf?id=133401039

I don't know enough about the workings of Flash and Xerte to make any changes here but if you are able to add some code that will make the rlo or rlt file name  (or even just the extension)  accessible as a property I can test against, then I could use this as my test for desktop V XOT / pageTemplate.

Kind regards

Hello Julian,

_level0.contentXML._url - this returns undefined

_level0.engine.contentXML._url  or rootIcon.contentXM._url both return

file://C:Xerte2\XMLEngine.swf?id=77679910

(my install folder is C:\xerte2)

Kind regards

Test this:

It should be the url to the rlo / rlt file, with the extension on the end.

Yes, I think that will work. In any case, any engine test could also be written in the template.rlt, it will only use the same information to judge the situation.

Some usful thigns for testing environments:

if the LO has template data...
if a page has templateData...?
if mdm != undefined you are at design time in xerte on windows
if templatePath != undefined you are on a toolkits server else you're not.

They don't at the moment, but I think you need an engine-side test. I'll write something for you.

Would it ever be the case that a XOT project would assign a value to a page Icon's templateData property?

If this would never happen then I can just reverse the original test, instead of testing for a project extXML I can test for pageIcon.extXML

if (pageIcon.extXML != undefined){
// Page Wizard

What do you think?

Kind regards

Neither am I.

I was going to ask you if you had any ideas where I would be able to access it.

Is the project file in a XOT project always called template? as in template.rlt.

It might be easier to check the file name rather than the extension as this will be available in templateData.

Kind regards

Hello Julian,

Thanks for a quick fix - all tests so far suggest this has solved the problem :-)

Now that I am working on a default .rlo file for the "page projects" I am including a template and xwd file which is resulting in there being an extXML, it also means that now the project can take the project name from the extXML file just as with pageTemplates / XOT.

So I need a new test for identifying when the model is in XOT / pageTemplate projects and when it is in a desktop project.

What I would like to do is work on the principle that in XOT / pageTemplate projects the setup script will define a variable "xMode"

Then I can replace the original block

if (extXML == undefined){
   // Page Wizard
   pageIcon.templateData = pageIcon.extXML.toObject();
   pageIcon.templateData = pageIcon.templateData.pageWizard[0];
} else {
  // Toolkits
  myXML = new XML(extXML.firstChild.childNodes[rootIcon.getPageIndex() - pgOffset]);
  pageIcon.templateData = myXML.toObject();
  rootIcon.setTitleText(templateData.learningObject[0].name);
}

with

if (xMode == undefined){
  // Page Wizard
  pageIcon.templateData = pageIcon.extXML.firstChild.toObject();
 // pageIcon.templateData = pageIcon.templateData.pageWizard[0];
} else {
  // Toolkits
  myXML = new XML(extXML.firstChild.childNodes[rootIcon.getPageIndex() - pgOffset]);
  pageIcon.templateData = myXML.toObject();
  // rootIcon.setTitleText(templateData.learningObject[0].name);
}
rootIcon.setTitleText(templateData.learningObject[0].name);

The commented lines of code would be removed - they are just there to make explicit the changes I am proposing.

Not requiring to define a value for xMode in a desktop environment would make it easier to use the models in a pure desktop project (i.e. one in which the developer did not even use the "Create new Page Project option"), but it would need that all XOT projects and future pageTemplate projects had the xMode variable set.

What do you think?

Given that the line
rootIcon.setTitleText(templateData.learningObject[0].name);

works, would it also mean that if we had a method for the page icon to set it's title property that we could use

pageIcon.setTitleText(pageIcon.templateData.pageType[0].name);

As a way of overcoming the problem of using the name value to set up the page title display (probably wouldn't sort out the display of page titles in the TOC though) mmm.

Kind regards

Johnathan

Subject: [Xerte-dev] Xerte editor closes if you add a setup script to the Learning Object icon

I've been doing some tests as part of establishing a standard pagetemplate.rlo file for the new version of the xerte editor that handles individual page templates..

However I have hit a problem. I want to include one or more set up scripts as children of the Learning Object.

If you add a setup script then this breaks the process of adding a new page. The folder for the page is created in the "pages" folder and the xwd and xml files are created in the page's folder. However the insertion of the page model file into the project fails. This means that if you select "Yes" when the "Open the wizard" prompt is displayed then Xerte collapses to the task bar and won't open again.

If you then close down Xerte and then re-open the project the project behaves correctly until you try adding another page.

Kind regards

Johnathan
