Thanks for your answers.
Asley: i bumped because this could be a base bug in the uid system, which 'could' have priority. and if so, i can not continue my (simple) project because this old uid object instancing feature. (so glad c2 currently works on my laptop, and got some time ^^ )
Should i wait for feedback before continue working (and trying to fix) on the project?
PS: I think a status indicator would be useful for any bug-report, to get feedback about its relevance, and if you are working on it. Some people are using c2 in a productive environment, and dont have weeks time for eventually getting an answer <img src="smileys/smiley1.gif" border="0" align="middle" />
telle: i've been reading this stuff long ago, if i could understand why the uid's does not work in this project, i would not have had posted <img src="smileys/smiley1.gif" border="0" align="middle" /> Please download the capx, and try yourself.
