I want to add a new component in the library ThermoPower.

I added a new package in ThermoPower package.mo.  Then I added mypackage.mo in the file of thermopower. And I added the name of my package in the file .order

But when I wanted to open package of thermopower, it wrote "missing name water thermal ..." All package already present in thermopower.

How can I add a new component in the existing library?

Thanks

Best regards
