Im generating a form field using php on Symfony like this:

In summary, my problem is how do you easily make a connection resource a global variable? To be specific, I'd like to open a Redis queue connection and would like to use that in multiple functions without the hassle of passing it as a parameter, i.e.'

\n\n
#===============================================================================\n# Global variables\n#===============================================================================\nREDIS_QUEUE <- how to initialize\n
\n\n

Then, in my main function, have

\n\n
# Open redis queue connection to server\nREDIS_QUEUE = redis.StrictRedis(host=SERVER_IP, port=6379, db=0)\n
\n\n

And then use REDIS_QUEUE in multiple functions, e.g.

\n\n
def sendStatusMsgToServer(statusMsg):\n    print \"\\nSending status message to server:\"\n    print simplejson.dumps(statusMsg)\n    REDIS_QUEUE.rpush(TLA_DATA_CHANNEL, simplejson.dumps(statusMsg))\n

My game needs to fill tableView cells with a bunch of things from my server database. This has been working fine. Then I upgraded Xcode to 4.6 and targeted iOS6.1, to please the App Review Team folks. Now, one of my connections never completes. (All of the other Posts seem to work correctly, as always.) Here's my post:

\n\n
- (void) fillCells {\n    Cell_QtoA *newCell = [[Cell_QtoA alloc] initCellUser:usrID Grp:grpID Qtn:0 Gnm:@\"na\" Cat:@\"na\" Sit:@\"na\" Pfl:@\"na\" Lks:0 isA:0 ddA:0 ];\n    NSMutableURLRequest *reqPost = [SimplePost urlencodedRequestWithURL:[NSURL URLWithString:kFillCells] andDataDictionary:[newCell toDictC]];\n    (void) [[NSURLConnection alloc] initWithRequest:reqPost delegate:self];\n}\n
\n\n

I think it's working fine. The PHP and database haven't changed. Everything worked great yesterday, before the upgrades. Here's my connection method:

\n\n
- (void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {\n   NSLog(@\"data = %@\", data);\n   NSString  *error;\n   NSArray *array = (NSArray *)[NSPropertyListSerialization propertyListFromData:data mutabilityOption:NSPropertyListImmutable format:0 errorDescription:&error];\n   if( error ) {\n       NSLog(@\"Error = %@\", error);\n       return;\n   }\n   NSLog(@\"1st object in array of %d is %@\", [array count], array );\n}\n
\n\n

Because I suspected net speeds to be an issue, I added a timer to the call, which I never needed before:

\n\n
timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(fillCells) userInfo:nil repeats:YES];\n
\n\n

The timer didn't help. Still get errors:

\n\n
\"Unexpected EOF\" and \"Unexpected character z (or whatever) at Line 1\"\n
\n\n

The NSLog of data shows hex data that appears cut off, like:

\n\n

I am about to release an update to my application to use the new JavaScript Google Charts API having taken note of the deprecation warning against the Google Image Charts API. I am encountering JavaScript issues with the axis labelling apparently dependent on the version of the Android WebKit. I am aware that using the Google Charts API simply won't work pre-3.1 owing to the lack of SVG support within the Webkit client.

\n\n

Background

\n\n

The application currently supports Eclair (API Level 7) upward with SVG support only arriving on the in-built WebKit client in Honeycomb MR1 (API Level 12). To address this discrepancy in functionality my code employs a simple if-else statement inspecting the Android version prior to deciding which charting API to use.

\n\n

The rendering issue

\n\n

This is best shown with a picture. Please note that;

\n\n
    \n
  1. The same JavaScript is being run on the Android Honeycomb Emulator as on the Jelly Bean device.
    2. \n
  2. The comparison is between an emulator (not working) and a real phone (working)
    3. \n
  3. The JavaScript is being run from within a WebView leveraging the in-built android.webkit.WebViewClient
    4. \n
  4. The axis on the emulator show as [Object object] but correctly on the real device
    5. \n
\n\n

\n\n

\n\n

Figure 2 - The correct axis labelling found on the Real device.

\n\n

The code

\n\n

Without 'paste-bombing' the issue with masses of irrelevant code the bits of JS and Java driving the naming of the vertical (v) axis are described below;

\n\n

JavaScript

\n\n
...\nAs part of the chart options...\n...\n// Vertical axis.\nvAxis: {title: yAxisTitle.toString(),\n        baselineColor: 'white',\n        titleTextStyle: {color: 'gray'},\n        textStyle: {color: 'gray'}, \n        gridlines: {color: 'gray'}\n        }\n
\n\n

where yAxisTitle has been injected in via the Android WebView.addJavascriptInterface like so;

\n\n

Java

\n\n
chart.addJavascriptInterface(String.format(getString(string.height_label), getUnits().getSymbol()), \"yAxisTitle\");\n
\n\n

Investigation to date

\n\n

From briefly encountering the [Object object] description previously (I'm new to the world of JS) I understand that I am simply executing a toString on a JavaScript object and that's what it looks like. But does this mean there has been a change in Java-JavaScript injection between Android 3.1 and 4.1 which means the datatypes being inject via the addJavascriptInterface are now being 'remembered' whereas previously they were not? Should I be serialising the string into a JSON object or is that overkill for what is passing an (almost) primitive type? Finally should I be explicitly casting on the JS side to enforce that the sorts of objects being used for items such as axis labels are indeed strings? Thoughts appreciated.

I'm loading data using jQuery (AJAX), which is then being loaded into a table (so this takes place after page load).

\n\n

In each table row there is a 'select' link allowing users to select a row from the table. I then need to grab the information in this row and put it into a form further down the page.

\n\n
$('#selection_table').on('click', '.select_link', function() {\n    $('#booking_address').text = $(this).closest('.address').text();\n    $('#booking_rate').text = $(this).closest('.rate').val();\n});\n
\n\n

As I understand it, the 'closest' function traverses up the DOM tree so since my link is in the last cell of each row, it should get the elements 'address' and 'rate from the previous row (the classes are assigned to the correct cells).

\n\n

I've tried debugging myself using quick and dirty 'alert($(this).closest(etc...' in many variations, but nothing seems to work.

\n\n
