FreeMarker template error:
The following has evaluated to null or missing:
==> imgCnt [in template "enc/viewSpecies.ftl" at line 117, column 79]
Tip: If the failing expression is known to be legally null/missing, either specify a default value with myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing. (These only cover the last step of the expression; to cover the whole expression, use parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)??
The failing instruction (FTL stack trace):
----------
==> #if (imgCnt > 0) [in template "enc/viewSpecies.ftl" at line 117, column 73]
----------
Java stack trace (for programmers):
