Hi all,
It seems that when using background, \startitemize[columns] does not work as expected: there are no columns, and the numbers of the items are pushed to the left.
Below is a not so minimal example: the resulting PDF can be found here:
http://dl.dropbox.com/u/4316076/enumeration-background-exo.pdf
I am not sure whether this behaviour began with a recent beta or not.
The version I am using is: ConTeXt ver: 2012.01.16 18:33 MKIV.
Best regards: OK

You can use the columns environment (which is used by itemize) in a framed, framed text or background environment.
What you can do is to replace the background environment with text background or you use the simple columns environment which does work in framed etc.

Thanks Wolfgang for your attention.
Now that you mention this, I understand that the columns environment cannot be used at the same time as framed or background environments. Is this a definite barrier?
As a matter of fact changing background to textbackground (as you suggested) did not work neither.
Have a nice day: OK

It’s not a limitation of the mechanism \startcolumns uses to make multiple columns because the same mechanism is also used by \startsimplecolumns but of the implementation of the command. When you search the list archive you can find examples with streams which permit columns in \framed etc.

Thanks fo rthe explanations: indeed with my previous setups for having each exercise with a vertical rule at its left, the following modification works fine when I need items in two columns:
\startsimplecolumns
\startitemize[r,packed][margin=standard,stopper=,left={(},right={)},distance=1em]
\item $3x - 5 = 4$.
\item $(x-1)(x+3) = 5$.
\item $2 - 3x \geq 2 x - 8$.
\item $(x - 1) \leq (x-1)(x+2)$.
\item $2x^2 - 3x +1 < 0$.
\item $x^2 - 4x \geq x - x^2 - 1$.
\stopitemize
\stopsimplecolumns
Best regards: OK
