Hello, I found out that the memory leak is caused by the focus manager.
So concerning the warning about the module calling net.registerClassAlias() -> the module is garbage collected even when those warnings pops up in the console. Now I'm stuck with the focus manager causing a memory leak : After reading some blog posts about the correct way to handle module unloading (From Alex Harui ,Tom Sugden) I added a textInput in the shell application to which I give focus just before module unloading : Now if a module button is clicked or if the focus is given to a textinput without typing anything, the module instance disappears when the run Garbage collector button is pressed but if some text is typed in a textInput the module stays in memory. I used the debugger to see if the focusManager instance keeps a reference to a module control but I don't found anything. Any idea ? -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Memory-leaks-management-in-modules-tp3422p3482.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
