Your error is apparently in the createToolTip() method of a class called GridHeader. Monkey patching classes in Flex definitely works and is something I’ve done multiple times. The fact you still get the error message when using the built in class, along with the error message make it certain the problem lies elsewhere.

I tried this. I created a class in mx.managers and called it ToolTipManagerImpl. I put in your code suggestion for the createToolTip function. I get this error when create…

VerifyError: Error #1030: Stack depth is unbalanced. 1 != 0.
at my.class.path::GridHeader/createToolTip()

I backed out the changes to the function (using original flex code) and tried that.

Same thing.

I seem to remember trying to do things like this before. Flex does not like it when you use its packages to overwrite its own classes.

Hi Morten,

You don’t actually need to create a whole new SWC. To monkeypatch a class in Flex all you do is copy the class from the framework and save it in your project under the same package it came from. So in your project you would create mx.managers.ToolTipManager or whatever it is, copy in the code from the framework and then edit whatever it is you need. When your project is compiled it will use your local class instead of the one in the framework.

If thats not clear hit up Google, I am sure there is more info out there about monkeypatching Flex.

HTH,
Ben

I have just the same problem. I wan’t to use cutom tooltip with the “createTooltip” method.
I’ve tried patching my eclipse flex with the latest 3.1SDK all afternoon and evening – but to no avail! Either the patching doesn’t work (which i think might be the most probable thing) – or the patch does not live well with 3.1?

Can you go into a BIT more detail on how you actually do the patching (ie: create a “stub” SWC to include etc.) To me, it seems that, whatever I do, it’s the original flex sdk that gets called by my app…. arrrg

Morten

If I remember correctly – this ‘bug’ was marked deferred with a workaround. Workaround as in… if the bug sits long enough Ben will probably get sick of futzing with it and throwdown a monkey patch. Thanks for the bits Ben.
