exportNetwork with error code #3769

[Joyce Lin]

Hi, i try to use the exportNetwork function previously it worked fine. But now when i try to use it, the error #3769 will pop out. May I know what is the error code referring to? Thank you.

Hi Joyce,

  I have faced this error recently and it seems that it is causing from new flash player sandbox restrictions, as discussed here: http://stackoverflow.com/questions/23703920/flash-sandbox-security-error-just-started-popping-up-in-the-last-day-dead-in-wa if you are building CytoscapeWeb from the sources commenting out the lines that are related to headers in the following method below which is in GraphProxy.as will do the trick i guess:

        /**

         * Send the the network data to a URL.

         */

        public function export(data:Object, url:String, window:String="_self"):void {

            var request:URLRequest = new URLRequest(url);

            //var header:URLRequestHeader = new URLRequestHeader("Content-type", "application/octet-stream");

            //request.requestHeaders.push(header);

            request.method = URLRequestMethod.POST;

            request.data = data;

            navigateToURL(request, window);

        }

Thank you Istemi, I will give it a try.

Have you solved this issue? I got the same error and don't know how to solve it.

Hi,

I suggest you stop using exportNetwork() and use these functions to get the content you want:

png(): http://cytoscapeweb.cytoscape.org/documentation#section/png

svg(): http://cytoscapeweb.cytoscape.org/documentation#section/svg

pdf(): http://cytoscapeweb.cytoscape.org/documentation#section/pdf

graphml(): http://cytoscapeweb.cytoscape.org/documentation#section/graphml

xgmml(): http://cytoscapeweb.cytoscape.org/documentation#section/xgmml

sif(): http://cytoscapeweb.cytoscape.org/documentation#section/sif

Then use JavaScript/AJAX to post the content to the server.

Or you can save (download) the content using the HTML5 file APIs: http://www.html5rocks.com/en/tutorials/file/filesystem/

Thanks,

Christian

Hi,

Sorry to bug you about something so basic, but I am a molecular biologist, not a html expert. Still, I need to get this thing running.

I have managed to get the cytoscape web working (e.g. http://aranet.mpimp-golm.mpg.de/responder.py?name=gene!ath!1), but I am also facing the 3769 error.

How exactly should I use the pdf() and what should the server-side script look like?  

Here is the function that I use for sending the network to my .py script (it was working before):

Coex.addContextMenuItem("EXPORT: as pdf", "network", //pdf()

function (evt) {Coex.exportNetwork('pdf', 'http://aranet.mpimp-golm.mpg.de/cgi-bin/cga.py?type=pdf&pfam=cluster');});

Here is the server-side script sending it to users:

if formatOf=="pdf":

    print "Content-Type:application/octet-stream;";

    print "Content-Disposition: attachment; filename=\"%s.pdf\"\r\n\n" % (pfamOf); 

    print data

Please let me know how to solve this. I am going slowly crazy here.

Cheers,

Marek

I got a solution after bugging a web-developer for 3 days: 

Coex.addContextMenuItem("EXPORT: as pf", "network", 

function (evt) {

        var netta = Coex.pdf();

contentType = 'application/octet-stream';

var a = document.createElement('a');

var blob = new Blob([window.atob(netta)], {'type':contentType, });

a.href = window.URL.createObjectURL(blob);

a.download = 'network.pdf';

a.click();

});

Hi there,

can you provide details on how exactly did you solve it?

I´m using the mini version.

Thanks Marek, I got the same error and solved it follow your solution.

My code:

  function fixBinary (bin) {

    var length = bin.length;

    var buf = new ArrayBuffer(length);

    var arr = new Uint8Array(buf);

    for (var i = 0; i < length; i++) {

      arr[i] = bin.charCodeAt(i);

    }

    return buf;

  }

$("#doexport").click(function(){

  var type = $("#exporttypes").val();

  var blob = "";

  var a = document.createElement('a');

  contentType = 'application/octet-stream';

  if ( type == 'png' ){

        var png = vis.png();

        var binary = fixBinary(atob(png));

        blob = new Blob([binary], {type: 'image/png'});

  }

  else if ( type == "pdf" ) {

        var pdf = vis.pdf();

        blob = new Blob([window.atob(pdf)], {'type':contentType, });

  }

  else{

        var FileContent = "";

        if ( type == "svg" ){

                FileContent = vis.svg();

        }

        else if ( type == "xgmml" ){

                FileContent = vis.xgmml();

        }

        else if ( type == "sif" ){

                FileContent = vis.sif();

        }

        else{

                FileContent = vis.graphml();

        }

        blob = new Blob([FileContent], {'type':contentType, });

  }

  a.href = window.URL.createObjectURL(blob);

  a.download = 'network.'+type;

  a.click();

});
