Unable to add text to HTML HEAD tag.

Answer 1

I've run into the same problem recently but the behavior wasn't predictable. I believe that Dan Short's answer is correct. I created some test pages to see if I could reproduce the problem. Each time TestTemplate.cfm is included, CFHTMLHEAD writes a simple JavaScript alert to the head tag. Once the buffer is reached, and the page is automatically flushed, any subsequent CFHTMLHEAD tag use will result in an error, specifically, the error in the original post. As Dan indicates, you can work your way around this issue by changing the maximum output buffer size.

file: index.cfm

 
cfset Count = 0>
 
 
 

file TestTemplate.cfm

Count #Count#




    
    j = randRange(i, 1000000);
    k = randRange(i, 1000000);
    l = j * k;
    writeOutput(l);
 

file sample.js

alert('Boo!');
