Can I call JET.news.create().more() more than one times?

Binglin Yu

I create a subscription like below:

var newsSubscription = JET.News.create()
.newsExpression("IBM.N")
.topSize(0)
.basketSize(1)
.onAppend(onAppendAll)
//.onInsert(onInsertAll) // I don't need latest news but historical ones
//.onDelete(onDeleteAll)
.start();
And call the "more()" function like
newsSubscription.more(1);
And in the onAppendAll function, I calculate out a number to see whether more historical news needed. If yes, call "newsSubscription.more(1);" again, which will trigger onAppendAll again. The loop continues, until I find the news I want.

This loop worked fine for some cases, until today I noticed a dead loop in Beta env. The same (unwanted) piece of news "urn:newsml:reuters.com:20141014:nDJJN01A50:2" continues to return (after around 20 rounds of correct callings) by newsSubscription.more(1), which caused the dead loop.

So, I tried to call the "more()" for once with bigger lines, like "newsSubscription.more(30)". And this time, everything returns well, and more news happening earlier than "urn:newsml:reuters.com:20141014:nDJJN01A50:2" can be returned successfully (which means there are news older than that).

So, my question is, can I call the "more()" functions many times? If nope, how to retrieve the latest piece of news I want in "history"?

Thanks.

Refer to JET.js API Demo (News Plugin -> Retrieving more headlines at runtime), subscribtion.more() can be called multiple times.

I got the same problem when using your snippet code but my app stuck at this headline:

Append: 29-Oct-2014 : 08:00:59 Fitch Solutions: IBM's CDS Reach Widest Level in 3 Years IBM.N urn:newsml:reuters.com:20141029:nFit809685:1

I will contact JET team to verify the problem.
