Re: [Help-smalltalk] Error while opening URL via FileStream

[Stefan Krecher]

Ok, this could be a bug in URIResolver.st:
the method that is responsible for creating a tmp-file calls:
dir := UserProfileSettings default settingAt: 'tmpDir'.
and dir is an empty string.
I guess it should be dir := UserProfileSettings default settingAt: #tmpDir.
this returns the correct value.
