I'm noticing some odd behavior with redirect when I set my app.context a certain way. I found a bug in the Grails JIRA which describes my problem perfectly, but it was marked as UTR: http://jira.grails.org/browse/GRAILS-7546
Here is my description of the problem:
I'm currently using Grails 2.0M2. I have the following properties defined in my application.properties file:
app.context=/
app.name=foobar
When I call redirect in a controller, redirect is adding the app name onto the uri I provide, which then causes a 404. Here is how I'm doing this:
String partialUrl = createLink(mapping: 'helloworld') // returns `/hello/world`
redirect(uri: partialUrl) // INCORRECTLY redirects to
// `http://mysite.com/foobar/hello/world`
// instead of `http://mysite.com/hello/world`
Assume that I have a URL mapping named helloworld defined in my UrlMappings.groovy file with a path of /hello/world.
So, long story short, if I set the app.context to /, I would NOT expect the app.name to show up in my final redirect URL.
Is this a bug or expected behavior? Any idea on the easiest way I could build up the redirect URL without doing too many manual steps?

I hate to say it, but I cannot reproduce it either. I created a test project with one controller (named Hello), using your code to create an action that does nothing but redirect:
package test1
class HelloController {
def index() {
def model = [:]
model.content = 'content...'
model
}
def redir() {
String partialUrl = createLink(mapping: 'helloworld') // returns `/hello/world`
redirect(uri: partialUrl) // INCORRECTLY redirects to
// `http://mysite.com/foobar/hello/world`
// instead of `http://mysite.com/hello/world`
}
}
I created an index page, index.gsp in the views/hello
<h1>index.gsp</h1>
<html>
<body>
<p>This data is coming from the model:</p>
<p>content: ${content}</p>
</body>
</html>
Setup helloworld in the UrlMappings to map to the index action of the hello controller:
class UrlMappings {
static mappings = {
"/helloworld"(controller: "hello", action: "index")
"/$controller/$action?/$id?"{
constraints {
// apply constraints here
}
}
"/"(view:"/index")
"500"(view:'/error')
}
}
And changed the application.properties to have the app.context=/
#Grails Metadata file
#Sun Nov 06 14:51:56 EST 2011
app.grails.version=2.0.0.RC1
app.context=/
app.name=test1
app.servlet.version=2.5
app.version=0.1
When I ran the app, I could go to localhost:8080/hello and it would show my simple GSP. I tried localhost:8080/helloworld and also got it as expected per the mapping. Then I tried localhost:8080/hello/redir and I was properly redirected to localhost:8080/helloworld.
However, if you're still facing this issue, I have a few suggestions
1) Try using the new link generator available in 2.0 instead of createLink. It may not do anything different, but worth a try: grailsLinkGenerator.link(mapping: 'helloworld')
2) If it's only on redirects from within controllers, you could just add the http://mysite.com portion yourself to the partialUrl.
3) Last resort, write a Filter attached to afterView that does a regex search and replace on the contents for mysite.com/foobar. Not sure this will catch redirects though, but if anything would, I'd assume this would be it since filters can be applied at broad level.

def yourAction = {
redirect(uri:"helloworld")
}
That doesnt work for you?
