ARB param gives artisan error

[James Whiffin]

Hi. I made a custom gradient UI param based on the sample Custom_ECW_UI, no issues except I need it to be an arb param to properly interpolate between keyframes. So I changed it to an arb param as per the ColorGrid sample. The UI behaves correctly, however once the effect is applied the project can never be saved (i launch the save command but the project remains untitled.aep) and I recieve this error on closing AE (same on windows + mac):

Anyone encountered such an error before? I must be doing something very wrong.

given this error truely is caused by your plug-in, i'd say it some memory corruption. this error makes no sense in the context of what you're doing, so memory corruption would make a sensible explanation.

do a thorough check of your arb param implementation. it's probably either a wrongly sized handle that causes you to overwrite memory beyond that handle's scope, or simply witing data onto a badly cast pointer.

Thanks for the suggestions Shachar. I think I'll just work with the ColorGrid sample from scratch and hope that the error doesn't appear.
