Problem Description:
Defining an implicit array in combination with the ternary operator in a <cfloop array> results in a crash or missing output (depending on the condition result of the operator).
Steps to Reproduce:
<cfscript>
str = "teststr";
arr = ["testarr1","testarr2"];
cond = "foo"; // crash
// cond = "bar"; // no crash, but output is missing
</cfscript>
<ul>
<cfloop index="e" array="#(cond IS 'bar') ? arr : [str]#">
<cfoutput><li>#HTMLEditFormat(e)#</li></cfoutput>
</cfloop>
</ul>
<ul>
<cfloop index="e" array="#(cond IS 'bar') ? arr : [str]#">
<li><cfoutput>#HTMLEditFormat(e)#</cfoutput></li>
</cfloop>
</ul>
Actual Result:
Crash, if cond = "foo":
Variable ___IMPLICITARRYSTRUCTVAR1 is undefined.
in the first loop: <cfloop index="e" array="#(cond IS 'bar') ? arr : [str]#">
Missing <li> in second <ul>, if cond = "bar":
<ul>
<li>testarr1</li> <li>testarr2</li>
</ul>
<ul>
testarr1</li>
testarr2</li>
</ul>
Expected Result:
With cond = "foo":
<ul>
<li>teststr</li>
</ul>
<ul>
<li>teststr</li>
</ul>
With cond = "bar":
<ul>
<li>testarr1</li> <li>testarr2</li>
</ul>
<ul>
<li>testarr1</li>
<li>testarr2</li>
</ul>
Any Workarounds:
Setting the array before <cfloop> works:
<cfset a = (cond IS 'bar') ? arr : [str]>
<cfloop index="e" array="#a#">
<li><cfoutput>#HTMLEditFormat(e)#</cfoutput></li>
</cfloop>
Loop in <cfscript> works, too:
<ul>
<cfscript>
for (e in ((cond IS 'foo') ? arr : [str])) {
WriteOutput("<li>#HTMLEditFormat(e)#</li>");
}
</cfscript>
</ul>
