[Pharo-project] [BUG]ByteSymbol(Object)>>error:

Dec. 20, 2009

      I also opened an issue http://code.google.com/p/pharo/issues/detail?id=1638 where the stack and a screenshot can be seen.

In a nutshell, when you use Method Finder and from there start a Browser, you get an MNU ByteSymbol>>hasWideCharacterFrom:to:.

Steps to reproduce:
1. Start the Method Finder
2. in the search pane write 'max:' and accept it
3. click in (first in my image) method 'detectMax:'
4. on the right upper pane click in "Collection detectMax:"

More details:

As can be seen in the screenshoot in the issue tracker, the method source *is
shown* but the Browser fails to render the method name's list and instead a
red with a yellow crossings appears instead.

If "venturously" another protocol is selected, the same red with yellow
crossing is shown and no more navigation to the method sources is possible.
