The table generated has all these columns, but java file has only columns from "component" tag. The first four members are missing. In general, when I deal with "component" or for that matter other classes that are being referred, do I need to specify any additional info?

Table looks fine
===========

PROFILE_ID
PROFILE_DISPLAY_NAME
PROFILE_EMAIL
PROFILE_BIRTHDATE
initial
first
last

please report this in jira

..and then don't ;)

just tested this and the problem is that you have this:

<meta attribute="generated-class">
com.automationschool.core.ProfileBase
</meta>

and meta attributes inherits by default, meaning the component will get it too.

use this instead:
<meta attribute="generated-class" inherit="false">
com.automationschool.core.ProfileBase
</meta>

thanks a lot. That worked.

I see now. Because it inherits, it quietly generates file with the same name for the component, overriding.

yes, i should probably error or warn on that situation.
