Question

This is probably one very simple question to answer, but I can’t output the variable I am trying to send to a view through a controller in the Grails Framework.

render(view: 'parseerror', error: it)

That’s my code in my controller, it renders the view correctly but as soon as I am trying to call the variable through ${error} it outputs nothing. It should output a string since when I print the iterator, the console output: The example string

Thanks for helping me out 🙂

The map key is “errors”, not “error”, but I belive, you want to achieve something similar to this code:

render( view: 'parseerror', model: [ 'error': error ] )
