How to iterate over a vector in freemarker?

I have an Object with a string vector as one of its attributes in the ftl. I have to use the if condition and enter a specfic block only when the vector contains some dynamic variable(available in the ftl)

I have tried to use the condition like

<#if (aObject.bVector.contains(dVariable))>

But this gives an invalid reference exception. bVector is populated with data in java layer but i am not sure if this method can be used or not.

You can use 

<#if aObject.bVector?seq_contains('value')>

Note than freemarker cannot access members directly: You need to have public accessors.

The aObject class also needs to be marked as public.

Source: FreeMarker Manual

Edit: Make sure aObject.bVector is not null.

it should go like this <#if aObject.bVector?seq_contains(dVariable?string)></#if>
