how translate the title from the component within the Installfile (.xml).
<?xml version="1.0" encoding="utf-8"?> <install type="component" version="1.5.0"> <name>COMPONENT NAME</name>
When the language it's british it's must show "Component Title". When the language it's the spanish language it's must show "Nombre del Componente", like a title of my very own componet within the Extensions Manager.
The component details are saved within the database. Doing the work how you have carried out won't work. I do not think this really is supported. An elementOritem must have 1 title. You should not have different names for the product/component. Microsoft don't call Home windows another title in The spanish language, German, etc - you want to do exactly the same.
With Joomla 1.6 you are able to translate it. See docs here.
For Joomla 1.5, you cannot.
