This statement:
new NumberFormat("#.##").format(12.33)
throws this error:
"Class 'double' has no instance method '&'"
Is it a bug or am I doing something wrong?
This is probably a known issue: https://code.google.com/p/dart/issues/detail?id=9215
I guess you don't need to worry about it, it should be fixed soon.

I've suddenly started getting a MissingMethodException in my Grails 2.2.5 app, without any change in code and the error is seemingly spurious, so I'm suspecting corruption somewhere. I'm getting this error:
No signature of method: arthurs.Sale.findByCustomerAndComplete() is applicable for argument types: (arthurs.Customer, java.lang.Boolean) values: [arthurs.Customer : 59, false]
Possible solutions: findByCustomerAndComplete([Ljava.lang.Object;). Stacktrace follows:
Message: No signature of method: arthurs.Sale.findByCustomerAndComplete() is applicable for argument types: (arthurs.Customer, java.lang.Boolean) values: [arthurs.Customer : 59, false]
Possible solutions: findByCustomerAndComplete([Ljava.lang.Object;)
This worked fine until yesterday. The Sale class does in fact have 'customer' (Customer class) and 'complete' (Boolean) properties, and I've checked that what I'm passing are valid parameters. In any case, the error message does specify the argument types and these are correct.
So why might my dynamic 'findBy...' method suddenly stop working? In the past I've often found doing a 'grails clean' often sorts such things out but it doesn't seem to have helped with this one.
Is there something else I should clear out, to give myself a blank slate?
Well, don't know what had happened there but deleting the project folder from '.grails/2.2.5/projects' did the trick.
LATER: No, the problem has returned. Very puzzled by this now.
LATER STILL: Well, I've now determined what it is that triggers the problem, although I am completely baffled as to why it does so. If I add a 'created' property of type Date to my Sale class, the problem recurs and remains until I remove the property, remove the column from the MySQL table, and delete the project folder. If, however, I mark this property as nullable in constraints, it works OK. ???
I have a problem with a code snippet I tried to play with, and since I am new to dart I don't really understand the error message. Can somebody explain to me why the error message says
The constructor returns type 'dynamic' that isn't of expected type
'widget'.
and how to fix it?
The class MaterialList doesn't exist. It looks like maybe you meant TwoLevelList, which is deprecated. You should try ListView instead.
If you have other import statements try to use alias as some libraries may be the reason for conflict.
Example: import 'package:html/parser.dart' as parser;
I read the other related errors and I have been unable to fix my problem
Please help me!
It is the common Expected expression in list of expression error.
Furthermore, I want to know if my error is connected to appdelegate.swift file.
Change
selector(MPCBrowser.requestFoundPeers(_:))
to:
#selector(MPCBrowser.requestFoundPeers(_:))
You forgot the # symbol that precedes selector in #selector.
Sometimes Idea cannot evaluate Groovy expression and rises an error: java.lang.IllegalArgumentException : Invalid method. You can check it on the screen - experiment variable exists and it should be displayed...
What's the problem and how can it be solved?
I think that problem can be in your object toString metod which deguger uses.
I'm getting an error when I'm trying to replace a GoTo in a while loop with a Continue, but whenever I do I get an error reading "Statement expected, but expression of type 'Boolean' found". Is continue a keyword not in Delphi 6? Does the error message mean something else?
Thanks.
It is in Delphi 5, so I would assume it is in Delphi 6.
There must be something else going on in your code, but without posting it, it's impossible to tell.
The error message means that somebody gave a variable the same name as the keyword and Delphi is using that instead of the keyword. Find the variable and try renaming it.
