MISSING_VAR in CFLOOP index

[bardware]

I have the following Coldfusion code and invoke CFLint like cflint.bat -file c:\folder\x.cfm -stdout -json from latest git checkout (1.2 release)

I expect 3 missing vars: xxx, strSel and idx. CFLint only lists two, idx is not regarded missing a var

<cffunction name="timePicker" returntype="string" hint="returns select" output="false">

    <cfsavecontent variable="strSel"><cfoutput>
        <select>
            <cfloop from="0" to="23" index="idx">
                <cfset xxx = NumberFormat(idx, "00")>
                <option value="#xxx#" <cfif xxx EQ 1>selected="selected"</cfif> >#xxx#</option>
            </cfloop>
        </select>
    </cfoutput></cfsavecontent>

    <cfreturn strSel>
</cffunction>

Hey @bardware - is that on ACF or Lucee?

@ryaneberly - this issue looks like as if it's related to what Harry recently reported and where we compiled that list of tag attributes to look for. Was cfloop/index maybe missed in there?

relates (a bit) to https://github.com/cflint/CFLint/issues/339

I'm on ACF

ah. this is good... the related issue https://github.com/cflint/CFLint/issues/339 dealt with the issue within the unusedvar plugin. Parsing these tag attributes needs to be moved up to the framework level.

This particular example is fixed, but fixing the concept of handling all variables created by CFML tags is deeper. I'm leaving this open, and the final fix will depend on some cfparser/cfdictionary changes.

This is TCO.
