ColdFusion Developer Week - 4th and 8th June, 2012
Hi All, We are conducting the 2nd ColdFusion Developer week happening from 4th â 8th June 2012. (Register here: http://adobe.com/go/cfdeveloperweek ) With the launch of ColdFusion 10, we are back with the 2nd ColdFusion Developer Week, a series of free, live webinars hosted by seasoned ColdFusion experts. The webinars cover a wide range of topics, from what ColdFusion is and how to code it, to more in-depth topics related to CF10- HTML5, REST, ORM, Security enhancements and more. If you are a new developer, someone with little or no ColdFusion experience, or even if you have been using ColdFusion all your life, these sessions are ideal for you. The ColdFusion Developer Week provides something for everyone so sign up now (http://adobe.com/go/cfdeveloperweek) Thanks, Rakshith Naresh Product Manager - ColdFusion Twitter: @rakshithn Blog: http://blogs.coldfusion.com ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:351362 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Wait for File to Get Written
maybe use cfdirectory and look at 'dateLastModified' to wait for it to be 2~5 old (so you know it has finished writing to it) Well, not sure that has any benefit by itself versus just checking if the file exists. I would make a retry loop, say 5 times with a sleep in between and break out if file found Okay, yeah this is more the piece I was looking for, a way to find the file quickly if it is there, while also ensuring that the page won't hang waiting for it if it doesn't complete. Yeah, this should work nicely, thanks!

Re: Wait for File to Get Written
You could also use cfthread. Spawn the execution off into another thread, then use the cfthread join action to make current processing wait until the child thread is finished and rejoined. Put your logic to check for file existence in the child thread where the execution of the external app is. Then you have a timeout on the join so that it won't wait around forever. Might be a bit cleaner separation.

Another CFDOCUMENT SUCK?
CFDOCUMENT has been the bane of my existence for years. Check out this simple dynamic PDF packaging code which should work... CFSET PAGEARRAY = [] / CFLOOP from=1 to=3 index=i CFDOCUMENT FORMAT=PDF NAME=PDFPAGE htmlbodydiv style=background:url(http://www.houseoffusion.com/_/hof120.gif)BRnbsp;/div/body/html /CFDOCUMENT cfset arrayappend(PAGEARRAY,PDFPAGE) / /CFLOOP CFDOCUMENT FORMAT=PDF NAME=PDFPAGE htmlbodydiv style=background:url(http://www.houseoffusion.com/_/hof120.gif)BRnbsp;/div/body/html /CFDOCUMENT cfset arrayappend(PAGEARRAY,PDFPAGE) / CFPDF action=merge name=FINALPDF cfloop from=1 to=#arraylen(PAGEARRAY)# index=i cfset pointer = PAGEARRAY[i]/ cfpdfparam source=pointer /cfloop /CFPDF cfcontent type=application/pdf variable=#tobinary(FINALPDF)# If you run this (on CF8 or CF9 - not tried 10) you will notice that the image appears only on the first and last page! Why? Because CFDocument ignores background images after the first call when in a loop. I was able to prove this by putting the call into a CFINCLUDE inside the loop. But then, if you add a CFDOCUMENTITEM to it, it throws an error: Routines cannot be declared more than once. According to Adobe there was a hotfix for this in CF8, although it did not work for me. Anyone know CFDoc well enough to present another solution?

Re: Another CFDOCUMENT SUCK?
Why not use one cfpdf with pagebreaks instead? Ray, this was a simple example to show the suckage. For the app, the data for various documents is coming from a database, and each one has different headers and footers. We already have all of the code which constructs the individual CFDocs successfully, and are merely trying to wrap it in a loop to stick them together into a single PDF. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:351368 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
cflayout and CKEditor don't play well together...sometimes.
I am using CF 9.1 on a Windows 2008 Web Server and have noticed another issue with cflayout(area). This (of course) only occurs in IE9. It works fine in Firefox. Let's say I build a cflayout page with 3 cflayoutareas (tabs). If I place a rich cftextarea (CKEditor) within tab 2 or 3 it does not display correctly. If I place the CKEditor in the first tab (or cflayoutarea) it displays and functions correctly? Besides the obvious, don't use cflayout and use jQuery libraries instead, does anyone have an idea of what is going on with the first cflayoutarea so that CKEditor works and force that to allow CKEditor to work in every cflayoutarea. Can anyone else dulicate the error and am I just missing something. According to a technical support email I got from Adobe they are aware of the issue(s) with cflayout and CKEditor. I just get so frustrated when cf tags don't work as they are promoted. I don't know of any other Adobe product where having broken features is acceptable: Photoshop, Illustrator, etc. Why is it Adobe allows ColdFusion to be sold knowing there are going to be problems with features. Then when they are made aware of them, don't fix all of them on an update release. While they do fix some, they ignore others. Then tell us it will be fixed in the next version I have to now pay for to solve their problemonly to find, as in past experiences, something else will break. I am getting very frustrated with Adobe's seeming lack of attention to ColdFusion and providing a totally clean product. I am also tired of the excuse that I get in emails from their support that we get the code for that feature from someone else and that's where the real problem lies. Really? Really! Rant over. Feedback welcome. And hopeful for a solution to my cflayout issue from all the experts in this group!

Re: cflayout and CKEditor don't play well together...sometimes.
FWIW JavaScript is notorious for being temperamental and causing problems when you start mixing JS libraries. You are using third party JS libraries along with the libraries used by CF. And practically speaking it is impossible to foresee and eliminate all possible conflicts when using multiple JS libraries at the same time, with or without ColdFusion. This is par for the course. I cannot tell you how many times I have run into problems when using multiple JS libraries/apps/plugins. Seriously though, comparing front end web development to Photoshop or Illustrator, where Adobe can control all aspects of the users/developers experience, is moot. Adobe has no way of foreseeing what you use in a web development project, let alone being able to find work-a-rounds for them. A lot of time the latest versions of popular JS apps come out after CF is released. Believe me, I understand your frustration... I wrestle with it on a regular basis. Just sayin'... G!
