Groovy/Grails Tools Suite (GGTS) code-assist in GSP pages for model objects

StackOverflow https://stackoverflow.com/questions/16166078

Question

I am a newbie in Grails, and still learning.

I have the following code for the model:

class Book {

    static constraints = {

    }

    String title
    String author
}

and controller:

class KillController {

    def index() { render "kill world"  }

    def view() {
        def book = new Book( author: "Mike", title: "nuff sed")
        [ model: book ]
    }
}

And for view.gsp, I have the following:

<html>
    <body>
        Author: ${ model.author }<br />
        Title : ${ model.title }
    </body>
</html>

Everything is working, and the correct output is produced. However, in the GSP editor, when I type ${ model. }, I don't get any proposals from code-assist. Pressing ctrl+space after typing the dot does not help.

Pressing Ctrl+space inside ${ } works though, and it correctly recognizes model as a Book object.

Is code assist for models not yet supported in the GSP editor? Thanks! :D

Was it helpful?

Solution

This is a bug. It should be working and it does in many other situations. When I try it, I do see that an exception is being thrown:

I'll have to see what is going on here.
