Found it, had a naming problem while i had appname in package.properties and that's why only that worked.
i created this property file: ClassName.properties in the ClassNames's path.
It contains:
appname = Loto
tooasltip = Home Page
In the code if i write: <s:text name="appname" /> it works and displays Loto
If i write <s:text name="tooasltip " /> it displays "tooasltip" instead.
What am i doing wrong?
I mention i just change the property name and leave the code in place, and it behaves differently for different property names.
Also the order the properties are defined in their file is irrelevant, as it should, what goes wrong then?
Same weirdness with <s:text name="getText('appname')" /> -it works, <s:text name="getText('tooasltip )" /> doesn't.
