Lectora 11 - multiple choice more than one answer bug

In Lectora X5/6 a multiple choice question with more than one correct answer can be defined in the AWT file as

Lectora X5/6 can read this in the AWT file and correctly setup the question.

However, with Lectora 11, if the allowmultiple="true" attribute comes BEFORE the questiontype attribute, then it will ignore the allowmultiple attribute. The odd thing is that it shows in the user interface as a set of checkboxes, but when you run the quiz you cannot get the question right.

If you simply edit the AWT file and move the allowmultiple AFTER the questiontype, it's OK.

This applies also if you import and XML file with the attributes in these orders.

It could be argued that the AWT is not XML, so it can do what it likes re attribute ordering, but when importing XML, there is no guaranteed ordering for attributes, so it should not make ordering relevant.

We are using Java and DOM to produce the AWT and when it parses our initial AWT template, it sorts all the attributes, hence they are written back sorted with the allowmultiple first and it's causing us a problem trying to use Lectora 11.

I have raised a bug.
