LiveCode Forums.

I am working on an iPad app and depending on user selection, I have an image being set to a url link like this:
Now this works for the most part. But the problem I'm having is simple navigating between cards with LiveCode. LiveCode crashes constantly on me when trying to work on other parts of my app. I have received the following error messages while working only with the cards containing these images:

Handler: tooltipUpdate
Handler: getUrl
Handler: ulHostNameToAddressCallback
Handler: mouseDown
Handler: updateForSelectedObjectChanged

I randomly get these handler errors with the same words:

"The handler: tooltipUpdate has reached the recursion limit of: 400000. Execution will be terminated to prevent hang."

I'm not sure what is going on here. I don't know if this is an error in my code or if this is something LiveCode is having an issue with, but everytime, LiveCode will throw one of these errors (never the same each time), hang up to the point to where I have to Force Quit the application. I am not using any kind of animation engine or anything, it's just changing the filename of an image depending on a selection.

Is anyone else running into anything like this? Any feedback would be greatly appreciated.

Hi cenglish,

I have no idea what is going on here, just tried your script and also had to kill LiveCode which did not surprise me!

BUT, on the other hand, what do you exspect when you set the filename of an image to an URL that points
to a DIRECTORY instead of a real image file on the server???
...
put "http://www.google.com/images/70987/" into urlAddress
set the filename of image "tImage" of card "main" to urlAddress
## a SLASH is definitively no valid image file suffix for LiveCode!

That wasn't the actual link I'm trying to use. I just made up some stuff as an example. The point I was trying to make is that if you set the filename of an image to a url (a very common use I would think) of an image, LiveCode crashes. My actual link that I use has images from a database through web services.

A better example would be:

I'm wanting to change an image to an image from a website. Is it not possible to do this?

Just tried your example code and it worked fine here.

and a rather bad one

There must be something else going on***, I also use this very often and never had problems setting the filename of an image to an internet url!

*** "tooltipUpdate" seems to be an internal LiveCode command!

Where does that chunk of code live? It's not in the image itself, is it?
