Question

This error has been popping up lately since I started evaluating Grails 2.0.0.RC3.
I make simple changes to a controller, then save.

From pictureList.count() which somehow worked in 1.3.7 but not in 2.0.0RC3

def tagged = {
        def pictureList = Picture.findAllByTag(params.id)
        render(view: 'list', model: [pictureInstanceList:pictureList, 
            tag:params.id, pictureInstanceTotal:pictureList.count()])
}

To pictureList.size() which makes more sense as pictureList is of type ArrayList

def tagged = {
        def pictureList = Picture.findAllByTag(params.id)
        render(view: 'list', model: [pictureInstanceList:pictureList, 
            tag:params.id, pictureInstanceTotal:pictureList.size()])
}

I get the compiling output message letting me know whats going on.

| Compiling 1 source files
| Compiling 1 source files.
| Compiling 1 source files..
| Compiling 1 source files...

Then I reload the page and I get this.

Now the only way to recover from the error(that I’ve found out) is to restart the application.

Has anyone come across this issue?? I’ll try to isolate the issue, if possible, so i can submit a bug report.

I should add that this app was originally based on grails 1.3.7 and I’ve recently upgraded it to 2.0.0RC1 and now to 2.0.0RC3

Answer 1

Do you use Intellij Idea and run grails app with it?
If so, you might try this temporary solution as offered on Idea’s issue tracker:

add enable.groovy.hotswap=false to /bin/idea.properties and restart IDEA.

This fixed this issue for me
