-----------------------------
Summary: Opening a .doc file under iOS causes the file system API
to break (and any other plugins that may use NSMutableArray pop)
Key: CB-877
URL: https://issues.apache.org/jira/browse/CB-877
Project: Apache Cordova
Issue Type: Bug
Components: iOS
Affects Versions: 1.4.0
Environment: Simple project that opens a word document in iOS 5.0+
Reporter: James Rose
Assignee: Shazron Abdullah
After getting the UIWebView to navigate to a .doc the FileSystem API breaks.
in javascript:
FileSystem.root.getFile(<path to word document>, { create: false }, function
(fs_file){
window.location = fs_file.toURI();
}
Then in the shouldStartLoadWithRequest method open the word doc, and after x
seconds redirect it the home page again (faster than creating a new view
controller etc).
Once back on the home page try call any of the FileSystem API's and they won't
run the success or failure callbacks.
It seems that the control that opens the word documents overrides the
NSMutableArray pop implementation added in NSMutableArray+QueueAdditions, it no
longer returns the first element in the array, instead it returns the last
element (checking the function pointer for pop before/after opening the word
document returns different results).
CDVFile seems to be the only code where the pop method is used, and seems to be
the only part that is broken.
Suggested fix: rather than calling [arguments pop] use [arguments
objectAtIndex:0]
Side note:
Calling [arguments objectAtIndex:0] followed by VERIFY_ARGUMENTS won't call the
callbacks if they exist either, in the verifyArgument method in CDVPlugin, if
you pass a callbackId to the method it then does:
NSString* callbackId = [arguments objectAtIndex:0];
and returns the failure to that callbackId rather than the one you specified,
since the callbackId has been removed from the array it will try callback on
the first parameter.
