I’m trying to export an image from a Qlik Sense mashup using the Visualization API ( viz.exportImg ).
It works but only for the very first app you open “AppA”, see example code below.
If you open another app ,”AppB”, before the first one the image export fails with error code: 2 (I have not found any documentation for what error code 2 means by the way).
If you however open the second app “AppB” after the first one “AppA” exporting images works but only ever for the first opened app. The “currApp” API call seems to follow this pattern, it only ever returns the first opened app.
Data export seems to work regardless of opening sequence.
Is this the expected behavior or is there a way to change the “active” app??
Example code:
var prefix = window.location.pathname.substr( 0, window.location.pathname.toLowerCase().lastIndexOf( "/extensions" ) + 1 );
var config = {
host: window.location.hostname,
prefix: prefix,
port: window.location.port,
isSecure: window.location.protocol === "https:"
};
require.config( {
baseUrl: ( config.isSecure ? "https://" : "http://" ) + config.host + (config.port ? ":" + config.port : "") + config.prefix + "resources"
} );
require( ["js/qlik"], function ( qlik ) {
qlik.setOnError( function ( error ) {
$( '#popupText' ).append( error.message + "<br>" );
$( '#popup' ).fadeIn( 1000 );
} );
$( "#closePopup" ).click( function () {
$( '#popup' ).hide();
} );
//callbacks -- inserted here --
//open apps -- inserted here --
// var AppB = qlik.openApp('SimpleAppB.qvf', config); // If i comment this line in the export stops working??? Why???
var AppA = qlik.openApp('SimpleAppA.qvf', config);
// var AppB = qlik.openApp('SimpleAppB.qvf', config); // Opening AppB here does not affect AppA export
//get objects -- inserted here --
AppA.getObject('QV01','Rwgz');
var CurrApp = qlik.currApp(this); // <- Allways returns the first opened app (see above)
console.log('CurrApp is: ', CurrApp);
var Imgsettings = { format: 'png', height: 300, width: 600 };
var Datasettings = { format: 'OOXML', state: 'A' };
AppA.visualization.get('Rwgz').then(function(vis){
vis.exportImg(Imgsettings).then(
function (success) {
console.log('Image download link: ', success);
}, function (error) {
console.error('Image export error: ' , error);
});
vis.exportData(Datasettings).then(
function (success) {
console.log('Data download link: ', success);
}, function (error) {
console.error('Data export error: ' , error);
});
});
} );
