ColdFusion wsPublish tag and destroyed session variable
January 9th 2018
95

We are back with a solution to another, perhaps not so widely known bug. This time it’s a ColdFusion native bug involving its own websocket and session variables. Frankly, it was bugging us (no pun intended)  for the past 2 years. Here’s the problem in detail:

We are running an application that utilises ColdFusion’s native websockets functionality. In a most basic scenario, we run a cfcomponent with several functions to create a notification record and insert it in the database. Then, as one would, push it via the webscoket so all the connected users with the relevant permissions receive it instantaneously. All is nice and well, right? NO.

Animate div with max-height using CSS and jQuery
May 11th 2017

Recently we ran into an annoying problem. Say you have a div with some dynamic text. Sometimes the text is short, so should be displayed in its entirety. Other times - it’s too long, so should be partly hidden. However, differently from hiding the text completely and then using jQuery’s .slideDown() of simply .show(), we wanted to display first few lines of it and give user the ability to show the rest. Also, and this part is very important - the revealing of the whole text should be animated (sort of the .slideDown() effect).

Coldfusion LinkedIn API

ColdFusion LinkedIn API

It’s been a while now that we were searching for a working ColdFusion LinkedIn API that would let users not only to receive data, but to submit some too. Although there were optional libraries such as linkedin-j, not everyone knows or wants to dip into the pure java world. Thanks to Derek Bowes, we stumbled across the LinkedIn.cfc which was a great plugin. The only trouble was that the plugin was already out of date since LinkedIn had updated their API in the second half of 2012, and now required member permissions were no longer a part of the original source code.

So we took the initiative to our hands and amended the plugin to allow users set the permissions required as well as the ability to post status updates.

But what if the settings box in question has some elements inside it that need a separate handling and should keep the box open? Read inside on how to skip document.one event in such cases.
