Wait for create image to complete...

I have an application that uses function in a cfc file. One function creates a jpeg from a byte array. This works fine. However, if I"m updating the image I need Flash to wait for the image to be created before it trys to reload it. How do I modify my code to wait and not do the return until the cffile action is complete?

<cffunction name="createJpeg" access="remote" output="false" returntype="boolean">
<cfargument name="send_image_data" type="string" required="yes">
<cfargument name="send_image_path" type="string" required="yes">

<cfset bindecode = BinaryDecode(send_image_data, "Base64")>
<cfset pathtowrite='#send_image_path#'>
<cffile action="write" file="#pathtowrite#" output="#bindecode#" nameconflict="overwrite" />

Thanks!

Try using FileOpen(), FileWrite(), and then FileClose() instead of cffile. Let me know how that goes for you!

I'm thinking you can probably use a <cfloop> tag to check for the file. Maybe you can try to read it in a loop? You'll want to have a timeout so that if there's a problem the whole thing doesn't hang. My coldfusion is a bit iffy but In pseudo code something like this....

set start = Now()

loop

if read file exit loop

if Now()-start GT 180 exit loop

sleep(1000)

endloop

Othewise, maybe using sleep() to wait for long enough to process the image way also work, though less efficient.

Hope this helps
