Dynamic loading of JavaScript libraries is broken in IE
-------------------------------------------------------
Key: TAP5-1731
URL: https://issues.apache.org/jira/browse/TAP5-1731
Project: Tapestry 5
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.3
Reporter: Howard M. Lewis Ship
Priority: Critical
Problem is in this code:
addScripts : function(scripts, callback) {
var _ = T5._;
var loaded =
_(document.scripts).chain().pluck("src").without("").map(this.rebuildURLIfIE).value();
var topCallback =
_(scripts).chain().map(Tapestry.rebuildURL).difference(loaded).reverse().reduce(
function (nextCallback, scriptURL) {
return function() {
this.loadScript(scriptURL, nextCallback);
}
}, callback).value();
// Kick if off with the callback that loads the first script:
topCallback.call(this);
},
In the nested callback, the "this" variable is not set to the right value, at
least not inside ie. Need to fully qualify
(Tapestry.ScriptLoader.loadScript()) or other bind this.
