It appears the only hurdle with compatibility is the change in charting system. For full page requests this is generally fine but in some spots we generate a chart in png format, capture the content generated and strip out some js that is generated simultaneously and return the result in json as part of a page update.

Develop Reference python amazon-web-services apache facebook ajax. Home About Us Contact Us. Is there a way to prevent cfchart from forcing js into response content? It appears the only hurdle with compatibility is the change in charting system.
For a response that should be json this is obviously a problem. I already tried calling a flush before the chart generates but then I get the error "ColdFusion was unable to add the text you specified to the output stream. This is probably because you have already used a CFFLUSH tag in your template or buffered output is turned off" when the cfchart code is hit.
Any suggestions on how to tell CF to put the code inline or otherwise reset the content planned for insertion into the request output? The chart gets added to the document on disk but then js gets output in the request response, killing our ajax requests that are meant to bring back the download link and other data. Found a workaround which is to to perform the chart generation in a thread. The output is then only the base chart content and not head content.
However I noticed that after testing, the included. Because each CFML file is compiled separately, and whether or not to output something is determined at compile time, not runtime. Set aside how ColdFusion works, you want to do this. Think of it as a poor mans' encapsulation. Someone should be able to use that included template without getting bogged down in the mundane details of the template that is being included.
I know there is cfcontent and cfsetting enableCFoutputOnly. What is the correct way to do that? You can delete whitespaces at the beginning of your document with it. Your result could be a single line of HTML which is then sent to the browser. Work with your web server to GZip and you'll cut bandwidth a great deal. In terms of tags, there is cfsilent In the administrator there is a setting to 'Enable whitespace management' Futher reading on cfsilent and cfcontent reset.
When you are asking solely out of aesthetic reasons, my recommendation is: Ignore the whitespace, it does not do any harm. I've found that even using every possible way to eliminate whitespace, your code may still have some unwanted spaces or line breaks.
If you're still experiencing this you may need to sacrifice well formated code for desired output. HTH Alternatively, You can ensure your entire page is stored within a variable and all this processing is done within cfsilent tags. Here's a tip if you use CFC. This will eliminate a lot of unwanted whitespaces. If you have access to the server and want to implement it on every page request search for and install trimflt.
It's a Java servlet filter that will remove all whitespace and line breaks before sending it off. Its configurable as well to remove comments, exclude files or extensions, and preserve specific strings. Been running it for a few years without a problem.
A set it and forget it solution. Empty page displayed with cfcontent in a popup unless manual refresh I have a ColdFusion page calling a cfm page as a popup through window.
The target page is a cfm that loads a PDF file. What is strange is that if I replace the caller page code from window. Do you have any suggestions here how to call the target page as a popup and having it load without the need of a manual refresh?
