Question

Invoking component from cffunction

Hi all,

I had a script in CF7 that used cfinvoke to call a cffunction from inside a different cffunction tag within the same cfcomponent tag. This all worked fine on my old CF7 server, but now on a new CF8 server it throws an error saying "Could not find the ColdFusion Component or Interface CFC.shoppingCart."

Any ideas anyone?

Thanks, Paul

    All's well that ends well.

    Could there be a name/type clash? What happens when you give the function a new name?

    Definitely not something new.

    I suspect something else has changed in the environment that you either
    don't know about or don't htink is relevant so didn't tell us.

    Still: it works now, which is the main thing :-)

    If you get the same error, then you're calling the function from a page relative to which the CFC's path is different from CFC.shoppingCart. There are three paths to consider. What is the path of the shoppingCart CFC, of the page containing the function and of the page that calls the function?

    BKBK,

    The calling page is mysite.com/page.cfm and it calls the cfc as cfc.shoppingCart.
    The shoppingCart cfc is mysite.com/cfc/shoppingCart.cfc

    The error it gives is Entity has incorrect type for being called as a function.

    Thanks,
    Paul

    Trying to get a shared hosting provider to restart a service on their boxes can be quite a frustrating task. If for some reason you can't test the application on a local development machine, you could always just change the name of the CFC and test against the new CFC. You shouldn't have any problems with coldfusion pointing to an old version of the component.

    Can you browse to http://yoursite/CFC/shoppingCart.cfc?

    Do you have a CF mapping called CFC, pointing to the dir that has
    shoppingCart.cfc in it?

    CF needs to know how to find the CFC file.

    Thanks for your reply Adam,

    I can browse to http://yoursite/CFC/shoppingCart.cfc, but it shows an empty page.

    I do not have a CF mapping called CFC, pointing to the dir that has shoppingCart.cfc in it, nor did I have on the old server.

    There are various other functions within the site that use functions from this cfc without issue, but it seems to fall down at the point where a cffunction uses cfinvoke to call another cffunction in the same cfcomponent.

    Thanks,
    Paul
