Re: [flexcoders] ArgumentError: Error #2004: One of the parameters is invalid@Graphics/drawRect

it depends on your code.
error finding method: comment half of the block. If its still the same
error, the mistake will be in the other half. if it stopped the error, the
error is in the commented half. repeat for the half with the error. repeat
until you found the problem..

the error is because: if you draw something, change a label, etc.. so
anything with a visual change, it won't change immediately, but every 1/24
second (by default) there is a timer event in Flex to apply that changes.
So this error comes when the program refreshes its view. (you know because
of the last row of the error:   at flash.utils::Timer/tick(), and goes to
flex sdk, not your code..) you get very similar error, when you want to
addChild() to an Element for example..

hope I helped..

yes, but you trigger it, because the drawing and other visual functions are
not called instantly, but on every timer tick, and the timer's speed is 24
ticks/sec by default. so at every tick spark askes every component if the
visuals have changed, and if so, calls the redraw, and thats where it goes
back to your code..

Re: [flexcoders] ArgumentError: Error #2004: One of the parameters is invalid@Graphics/drawRect

2011-12-06 Thread Alex Harui
This error occurs when a components gets drawn at a really small size and its 
constraints compute out to be invalid.  For example, if you have:

s:Rect left=”2” right=”2” /

Once the component containing this rect is only 3 pixels wide, the width will 
be computed as –1 since the left side will be at 2 and right side at 1 and 
(right – left) = -1.

We don’t check for these conditions for performance reasons, and try to get the 
minWidths to defend against it.

In the debugger, you should be able to double-click on the draw() in the stack 
trace then examine properties to determine which rect it is.
