Error while using String.replace("{cost}");

Hey guy's
I got a problem while replacing the String "{cost}" in another String:
the code at line 144 is: msg.replace("{cost}",[...]);
here is the error:

Code:

Because this is not related to my code, i don't know whats wrong.
thanks for help!
edit: it also fails with "//{cost//}"

 

Try it like this: "\\{cost\\}"

 

sorry, i used the wrong ones, this is the code:

Code:java

msg = msg.replaceAll("\\{cost\\}", iConomy.format(cost));

Code:

Well this is a different exception, which is thrown by iConomys format function. What exactly do you pass to it (e.g. what does the variable "cost" contain, and which type is it?)

 

Try String.replace("%cost%", iConomy.format(cost)); You only need to use %cost% in the config file instead.
