Dear all
I’m sure I’ve seen this before, but can’t find a solution this time…
<cfset str = "[[1234,1.2345],[5678,null]]">
<cfset xx = deserializejson(str)>
<cfdump var="#xx#">
<cfoutput>
1.len #arraylen(xx[1])#<br/>
1.1 #xx[1][1]#<br/>
1.2 #xx[1][2]#<br/>
2.len #arraylen(xx[2])#<br/>
2.1 #xx[2][1]#<br/>
2.2 #xx[2][2]#<br/>
</cfoutput>
The dump shows 2.2 as empty:null
The output is as I would expect: 1.len and 2.len both are 2
The error occurs at 2.2 : Element at position [2] does not exist in list.
If this element doesn’t exist, then obviously isnull(xx[2][2]) or isempty(xx[2][2]) produce the same error.
So how can I detect that null? A try-catch seems a bit heavyweight.
