[NTG-context] \noindent in startstop block is not working on the text that follows the block

I defined a startstop block. However, the text that follows the block I don't want to be indented. <Code> \definestartstop[Center][ before={\startalignment[center]}, after={\stopalignment\noindent} ] \starttext \startCenter This is some text! \stopCenter I don't want this paragraph indent; however, it ends up being indented. \stopText <\Code> However, the text that follows the block is indented. How to I declare a \noindent within the startstop block definition that will work when the block is exited? Thanks, Bart
