Vector class in a Flex Library Project

Question

i seem to be having some problems with the Vector class in actionscript 3

in a Flex Project or an ActionScript Project it is possible to do this

var v:Vector.<String>;

But when i do the same thing in a Flex Library Project (to create an SWC) then i get the following error on that line of code 1046: Type was not found or was not a compile-time constant: String.

so when using Flex Library Project it fails..., but when i compile the same thing using compc there are no problems

any idea why only the library project is complaining about Vector ?

btw this happens with all kinds off Vector declarations , not just String

var v:Vector.<String>
var v:Vector.<Number>
var v:Vector.<Object>

etc, all fail...

(i am using flex 4 sdk)

Answer 1

Check if your are publishing for a version flash >=10

Answer 2

You might need the latest Player Globals SWC: http://labs.adobe.com/downloads/flashplayer10.html

Similar to this issue?

Answer 3

ok it seems with Flex Builder 3 it is not possible to specify a minimim required flash player version for a Flex Library project , that's why it wasnt working.

i have tested the same thing in Flash Builder 4 , and now it is possible to specify that player version , which it possible to compile the Flex Library Project.

Thx for the answers Tegeril and Patrick you pushed me in the right direction.

Answer 4

Make sure you set the "-target-player" compiler argument to "10,0,0".

Answer 5

add:

"-target-player 10,0,0"

under "Properties -> Flex Library Compiler -> Additional compiler arguments !

Then it works with Flex B. 3
