I use the following code to scan for all available WiFi-Networks:
[[CWInterface interface] scanForNetworksWithSSID:nil error:&err];
Usually I get a NSSet of Networks but sometimes I get the following error:
The operation couldn’t be completed. (com.apple.coreWLAN.error error
22.)
Error Domain=com.apple.coreWLAN.error Code=22
I haven't find anything about that error code 22. Is there a documentation or a solution for this?
Because I had another problem with CoreWlan(http://stackoverflow.com/questions/9943833/cwinterface-returning-no-data) i replaced it with Apple80211.framework.
This also is a workaround for this one...

My company is working on converting from ColdFusion to NodeJS with Express, I'm running into an error trying to update some data in SQLAnywhere.
I have one update function working with 5 pieces of data. I'm working on my second, with 23 data points, but I'm running into an error stating:
"Error: Code: -2006 Msg: Can not bind parameter(s)."
I can't find any information about this online, not even using the error code. Any help, or pointing me in the right direction, would be appreciated.
Turns out it was trying to save integers into "char" fields on the database. Odd that we never had this issue with ColdFusion, but using "String(…)" around the values seemed to solve the issue.
I am using Manifoldcf v2.7.1 and Solr v5.2.1 and trying to crawl Jira using the Jira connector and am getting the following error in Manifoldcf:
Error: Repeated service interruptions - failure processing document:
Error from server at (servername:port/solr/jira): String index out of range: -11
Note: I removed my server and port info from the error message
One of the error logs from Solr is showing the following at the top of the stacktrace:
java.lang.StringIndexOutOfBoundsException: String index out of range: -11
at org.apache.solr.request.macro.MacroExpander._expand(MacroExpander.java:144)
Don't know what is causing this area and how to fix it. Thanks in advance!
Turns out that there was a Jira issue with Java written in the comments section. I think that it wasn't being exited out properly by Manifold. To avoid this, I excluded this one issue that was causing issues from future crawls.
I am getting an error:
java.lang.NullPointerException
When I call:
<cfdump var="#posts#" top="2">
<cfset postsQuery = EntityToQuery(posts)>
dumping posts shows an array of objects as it should but for some reason the EntityToQuery(posts) is breaking. The error message is not one of the normal ones which tell you what line it broke on etc. its just the following struct:
message: [empty string]
StackTrace: java.lang.NullPointerException
TagContext: array[empty]
Type: java.lang.NullPointerException
Does anyone have any idea what could cause this? I think its data related but I don't know what to look for. Its only happening on one implementation of this code, not the others im working on.
Strange errors stopped the next time the coldfusion service was restarted.
So if anyone else has that problem.... give restarting cf a try
In my application I have integrate Three20 Library and Restkit framework, after this I am Build the code the error was generated
the error is :
`"Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1"`
and the error description is
ld: duplicate symbol _OBJC_METACLASS_$_RKJSONParser in /Users/pratikkanada/Desktop/Zipogo/Zipongo - working
version/RestKit/Build/Release-iphonesimulator/libRestKitJSONParserYAJL.a(RKJSONParser+YAJL.o) and
/Users/pratikkanada/Desktop/Zipogo/Zipongo - working version/RestKit/Build/Release-
iphonesimulator/libRestKitJSONParserSBJSON.a(RKJSONParser+SBJSON.o)
so, pls tell me how to solve this error
It seems that you have added that lib two times.
Please search libRestKitJSONParserSBJSON.a and (RKJSONParser+SBJSON.o) in entire code and you may found one of these added two times.
Simply solution is remove any one of two same files.
I am seeing the following error when trying to search using Lucene. (version 1.4.3). Any ideas as to why I could be seeing this and how to fix it?

In this same environment I also see the following error:

The same code works in a test environment, however not in production. Cannot identify any obvious differences between the two environments.
File permissions are wrong (it needs write permission) or your are not able to access a locked file that the current process needs.
