In my graphical application, I have a feature to export all pages to images, I have this exception which I don’t know where to start looking to solve it:

An infinite loop appears to have resulted from cross-dependent views.

Any one can help me to get an idea of this exception ? how to solve it ? or what causes such a crash ?

Here is the stack trace:

    Well there’s not a lot to go on without any code to look at, but I’ll give it a shot anyway.

    The first step is to make the views less dependent on each other. Perhaps have a model that they both look at rather than having them look at each other.

    Another step might be making the update code only do an update when needed. Sometimes, when I have a control that changes another control and I put in logic to update it when the other control changes, I find my update stuff is being called when no change is really needed. For example, if some event results in the resize of a control, you might want to calculate the new values and then ONLY change the size properties if they have actually changed. (ie: aren’t the same as the new values)

    Hope this helps…
