Sahi Ruby 1.3.0 and Sahi 6.0.1 incompatibility on fetch()

dave

until Sahi 6.0.0, fetch is define in sahi ruby 130 :

def fetch(expression)
key = "___lastValue___" + Time.now.getutc.to_s;
execute_step("_sahi.setServerVarPlain('"+key+"', " + expression + ")")
return check_nil(exec_command("getVariable", {"key" => key}))
end

But, in Sahi 6.0.1 "setServerVarPlain" was rename in setServerVarForFetchPlain in concat.js

So, librairy Ruby Sahi is not compatible with Sahi 6.0.1

fetch must become :
def fetch(expression)
key = "___lastValue___" + Time.now.getutc.to_s;
execute_step("_sahi.setServerVarForFetchPlain('"+key+"', " + expression + ")")
return check_nil(exec_command("getVariable", {"key" => key}))
end
