Checking the structure is existing or not

Here is my array loop which has structures inside that

I am looping over it and i need to skip those fields where the struct is not defined, howver i am getting everytime

Here is my code: 

<cfloop index="apos" from=1 to="#arrayLen(myarray)#">
<cfdump var="#myarray[apos].company#">
    <cfdump var="#StructKeyExists(myarray[apos].company,'#myarray[apos].company.size#')#">
    <cfdump var="#StructFindKey(myarray[apos].company,'myarray[apos].company.size','ALL')#">
</cfloop>

The error is throwing on line 3, where i am getting error: Element COMPANY.SIZE is undefined in a CFML structure referenced as part of an expression.

Although i had tried the structFindvalue, but that does not work, perhaps that is expecting some simple values, so what could be the best possible alternative here

With structKeyExists you want to give that function the struture to look and the key you're looking for, so in myarray[apos].company you want to see if 'size' exists, not the entire structure.

<cfloop index="apos" from=1 to="#arrayLen(myarray)#">
  <cfdump var="#myarray[apos].company#">
  <cfdump var="#StructKeyExists(myarray[apos].company,'size')#">
</cfloop>
