I just wonder how I messed up the environments on those machines I
tested this on.
Maybe I should try to better describe what the problem is instead of
hoping that someone else would see the effect:
- while loading the page a TreeVirtual is created.
- TreeVirtual creates the SimpleTreeDataCellRenderer
- in the defer method of SimpleTreeDataCellRenderer the following is
called
qx.theme.manager.Meta.getInstance().initialize();
- in initialize the following block is called
theme = setting.get("qx.theme");
if (theme)
{
obj = qx.Theme.getByName(theme);
if (!obj) {
throw new Error("The theme to use is not available: " + theme);
}
this.setTheme(obj);
}
- theme is set to 'example.theme.Theme' (or whatever your application
is named after). This theme is not found in qx.Theme.$$registry and
therefore null is returned by getByName ... what results in the shown
error.
My question now is: the $$registry is filled while loading the different
theme things (I don't understand the details), but why is
example.theme.Theme excluded? Who would be responsible for loading the
file? Why is it visible in the list of "downloaded" files? Is it loaded
to late (why?)?

No I didn't, but would this be required for a brand new project?

You are right of course ...
Cheers,
Gereon
