Reason: I had installed and removed but still the entries in the registry was creating the issue.

Solution:

To uninstall Windows Live Writer, click Start, then type/paste the following and press Enter:

msiexec /x {178832DE-9DE0-4C87-9F82-9315A9B03985}

    static constraints = {
       password(size:6..32,blank:false),
       email(blank:false,email:true)
    }
}

Is there a way where I can validate only my password?
YES

if(user.hasErrors()) {
    if(user.errors.hasFieldErrors(“password”)) {
       println user.errors.getFieldError(“password”).rejectedValue
    }
}

In Grails.
int paramValue – param.int(“paramName”)

how sleek….

In the process, I got the following (misleading error)

126: The specified module could not be found – ../mysql_api.so

But mysql_api.so was in the path where ruby was looking for.
Solution:
Make sure your MySql bin path is in your PATH variable.

Thanks to this link. The problem was in my AVAudioSession Category which was set to AVAudioSessionCategoryRecord while it should have been AVAudioSessionCategoryPlayAndRecord.
