FlexCelReport.ExpressionRecursionLimit Property
Defines how much nesting you can have in Expressions before FlexCel throws an error. You might have an expression like <#A> which is defined based in another expression <#B> which in turn is defined based in another one that finally might come back to <#A> As it is not possible for FlexCel to know if the recursion will finish or loop forever, it will try until it reaches the limit you set here. Note that a too big limit could cause a stack overflow.
