    <p>Based on my tests you have to wrap the insert in code I tested that is similar to the above example.</p> <p>For example, I did this and it still failed with Fibers error.</p> <pre><code>function insertPost(args) { if(args) { Fiber(function() { post_text = args.text.slice(0,140); T.post('statuses/update', { status: post_text }, function(err, reply) { if(reply){ // TODO remove console output console.log('reply: ' + JSON.stringify(reply,0,4)); console.log('incoming twitter string: ' + reply.id_str); // TODO insert record var ts = Date.now(); id = Posts.insert({ post: post_text, twitter_id_str: reply.id_str, created: ts }); }else { console.log('error: ' + JSON.stringify(err,0,4)); // TODO maybe store locally even though it failed on twitter // and run service in background to push them later? } } ); }).run(); } } </code></pre> <p>I did this and it ran fine with no errors.</p> <pre><code>function insertPost(args) { if(args) { post_text = args.text.slice(0,140); T.post('statuses/update', { status: post_text }, function(err, reply) { if(reply){ // TODO remove console output console.log('reply: ' + JSON.stringify(reply,0,4)); console.log('incoming twitter string: ' + reply.id_str); // TODO insert record var ts = Date.now(); Fiber(function() { id = Posts.insert({ post: post_text, twitter_id_str: reply.id_str, created: ts }); }).run(); }else { console.log('error: ' + JSON.stringify(err,0,4)); // TODO maybe store locally even though it failed on twitter // and run service in background to push them later? } } ); } } </code></pre> <p>I thought this might help others encountering this issue. I have not yet tested calling the asynchy type of external service after internal code and wrapping that in a Fiber. That might be worth testing as well. In my case I needed to know the remote action happened before I do my local action.</p> <p>Hope this contributes to this question thread.</p>

    1. CO<deberg> [02:33:57] that's a bad answer, i should comment on that. <deberg> [02:34:20] that does create a Fiber, but it doesn't set up the useful meteor context inside it, and it doesn't actually block the outer method on the inner thread.

    2. CO@TomWijsman which is accurate then? Fiber around the entire block of code in the method?

    3. CO<deberg> [01:40:21] 1: unhook the write fence. see the implementation of Meteor.setTimeout in packages/meteor/timers.js for an example of this. <deberg> [01:41:19] 2: wrap whatever callback you've defined in a new fiber, so that the method doesn't return until your callback runs. that's how synchronous meteor APIs are implemented, like in packages/mongo-livedata/mongo_driver.js <deberg> [01:42:02] the right answer is actually 3: yell at us for not implementing a decent synchronous API for whatever you're trying to do :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
