[Lemon-user] FilterNodes does not accept map adapter

[Wei Liu]

Dear Lemon users,

After reading subgraph adapters (
http://lemon.cs.elte.hu/pub/tutorial/a00009.html#sec_subgraphs) and map
adapters (
http://lemon.cs.elte.hu/pub/doc/1.2.3/a00524.html#ga6d57040954dfe0188f02540fe8cf3319),
I wrote code like this:


lemon::SmartGraph G;
typedef lemon::SmartGraph::NodeMap<bool> BoolMap;
BoolMap alpha(G, false);

// update alpha.
...
lemon::FilterNodes<lemon::SmartGraph> G_fg(G, alpha); // works fine.
lemon::NotMap<BoolMap> not_alpha(alpha);
 lemon::FilterNodes<lemon::SmartGraph> G_bg(G, notMap(alpha) ); // compile
errors.

The compiler gives errors as below:

Did I miss something obvious? I'm using lemon 1.2.3 and gcc 4.7

I appreciate for your help.
