@svickers2 That's exactly what it was! We're developing a few LTIs and serving them from the same domain. The message appears to be more informational than an actual error message. Thanks!

No, it hasn't. This is definitely an app that has unique name made up of my name, date, and time.

Hey everybody, I know, I just posted in here. I'm trying to solve multiple problems at once right now. I think they may actually be related in the future though. Right now, we're dynamically loading content into pages via jQuery using DIV ids. This usually works, but isn't always reliable, and we've run into problems with doing this in Firefox. The next iteration of this solution seems to be to load dynamic content from a page that creates dynamic content via an iframe with URL parameters that would inform the page which content to load. I can make this work easily enough, but the content is quite long, and so we get the infamous iframe scroller within the page, which we're really trying to avoid. It seems simple enough to add an "onload" function to the iframe, then create a function in our global javascript that basically gets the height of the content that was loaded into the iframe, then set the height of the iframe through the code using the scrollheight parameter. A solution like this can be found here: https://stackoverflow.com/questions/9162933/make-iframe-height-dynamic-based-on-content-inside-jquery-javascript The problem is that Canvas strips out the onload parameter to an iframe. Does anybody have any workarounds that they've been able to implement to dynamically resize iframe height to the height of the content that's contained within it? Thanks, Jarred

Hi everybody, I'm really hoping some kind soul can help me out here. I'm learning LTI development for a few different projects we have in the pipeline. I have a Hello World app that I'm learning with. I understand the XML, URL, and Manual Entry methods. I understand programming. I have an XML file that I've generated with the correct information. I'm stuck on what seems like the simplest thing though... When I try to install a new application on a sandbox course, I get the error message " This tool has already been installed in this context. Would you like to install it anyway?" With 2 options, "No, Cancel Installation" and "Yes, Install Tool". I get the same error message whether I copy and paste the XML, point to the XML, or even just add an app manually with only the Name, Consumer Key, Shared Secret, and Launch URL fields. I don't see how this tool could have been installed previously. It's a sandbox course on our main instance. The application Name, Consumer Key, Shared Secret and Launch URL are all very unique. I've made sure of it by appending my name and the date. I've also tried some really out there configurations. I still get the same message. Can anybody talk me through this? I'm not installing the app, just in case I end up overwriting something else that is going on in the background that I'm unaware of. I've searched everywhere for an answer to this question, but I seem to be the only one with it on the entire internet, lol! Thanks so much! -Jarred
