Titanium SDK 3.4.0, iOS 8 support ? about nl.fokkezb.infinitescroll HOT 9 CLOSED

Can you show me the XML and JS where you used it?

from nl.fokkezb.infinitescroll.

Let me try with the latest version of the widget before ... 🐤

from nl.fokkezb.infinitescroll.

Ok still crashing, hope this code will help you:
XML :
<TableView id="tableView">
<Widget id="is" src="nl.fokkezb.infiniteScroll" onEnd="loadMore" />
</TableView>

JS:

addManyToView = function(collection) {
var baseData, limitedVideos, newData;

baseData = $.tableView.data;
newData = [];
limitedVideos = Alloy.createCollection('Video', collection.first(_displayAmount));

limitedVideos.each(function(V) {
newData.push((Alloy.createWidget($.__widgetId, 'Row', {
video: V
})).getView());
});

$.tableView.data = baseData.concat(newData);
};

What Alloy version are you using? Does it work when using Alloy 1.4.1?

from nl.fokkezb.infinitescroll.

Currently using Alloy 1.5.0-rc3 with CLI version 3.4.0-rc4
Same with Alloy 1.4.1

here is the full error trace:

I don't see a call to $.is.init() in your JS snippet, nor the method loadMore you have in the XML snippet. The line mentioned in the error trace should only be executed if the widget is used in a list view, but it might also execute if it isn't initialised properly.

I do call $.is.init($.tableView) within my widget's constructor now, but the crash happens before the controller's code.
Looking into file://.../alloy/widgets/wz.StreamTableView/controllers/widget.js:31, I found out:

$.__views.is = Alloy.createWidget("nl.fokkezb.infiniteScroll", "widget", {
id: "is",
__parentSymbol: __parentSymbol
});
loadMore ? $.__views.is.on("end", loadMore) : __defers["$.__views.is!end!loadMore"] = true;
$.__views.tableView = Ti.UI.createTableView({
separatorColor: "#dbdbdb",
scrollsToTop: true,
minRowHeight: 0,
rowHeight: 0,
footerView: $.__views.is.getProxyPropertyEx("footerView", {
recurse: true
}),
id: "tableView"
});

If titanium is trying to instantiate your widget before creating the tableView, that'd explain a lot... no ?

edit: after moving the call to $.is.init($.tableView), I realise this issue is not related to iOS8 and also happens on ios7.1 copiled with Ti 3.2.3. To be continued tomorrow...

Could you try https://github.com/FokkeZB/nl.fokkezb.infiniteScroll/blob/master/controllers/widget.js ?

Alloy 1.5.0 has some weird changes to __parentSymbol

If it is being used in a required controller e.g. then it may point to the parent controller instead of a view ;)

Awesome ! Works flawless
Thanks a lot Fokke 👍
