using put on a map in velocity prints the instruction [duplicate]

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;

I have a map in a velocity template that is dynamically modified. A simplified example to illustrate the point is below.

#set($testMap = {})



## this stuff isn't static so I can't just create 

## the map as key-value pairs in the declaration



$testMap.put("a", "A")

$testMap.put("b", "B")



$testMap

The above generates

$testMap.put("a", "A") $testMap.put("b", "B") {a=A, b=B}

I don't want the "put" instructions to show in the template.

I suggest you initialize your map with entries:

#set (testMap = {"a" :  "A" , "b" : "B"})

  Hi, thanks for your input. I would have liked to do that but the map's contents aren't known when it's initialized; the put instructions are done later dynamically inside of a loop and a few conditions.

A similar question is here.

I don't think it's a duplicate; Map.put(K, V) returns the V which isn't the same as the string literal $testMap.put("a", "A").
