Hi all,

I am writing a docker to edit variables and have encountered a problem.
The KoVariableManager does not contain any variables even though the document 
does. I was wondering if I am missing something obvious. Here is a code 
snippet i use to count the number of variables. This code always returns zero 
even when the canvas corresponds  to a loaded KWord document that contains 
about 10 variables such as page number and date.
The KoVariableManager instance is always successfully retrieved.

Cheers,
Jos

KoVariableManager* getVariableManager(KoCanvasBase *canvas) {
    if (!canvas) return NULL;
    KoInlineTextObjectManager* inlineManager
        = dynamic_cast<KoInlineTextObjectManager*>(
            canvas->shapeController()->dataCenter("InlineTextObjectManager"));
    if (!inlineManager) {
        return NULL;
    }

    return inlineManager->variableManager();
}

int countVars(KoCanvasBase *canvas)
{
    KoVariableManager *manager = getVariableManager(canvas);
    if (!manager) return 0;
    return manager->variables().size();
}
