Re: Putting key/value pair into hashmap from velocity template

[Will Glass-Husain]

Hi Matthias--

There's no magic.  If there are parens, it assumes it is a method call

$abc.foo("data")

calls the "foo" method with the argument "data".

$abc.foo

would call either getFoo(), getfoo()  or (for a Map) get("foo")

Thanx Chris,

but this doesn't solve the problem. :(
It's  still the same error.
I also tried to use the method set(index, object) from arraylist, but this also 
doesn't work.

I guess that velocity does "some magic" and don't calls the put-method from 
hashmap or the set-method from arraylist.

I have verified both tests by calling the methods clear() and size() on hashmap 
and arraylist to be sure, that the objects exists in the velocity context.

I have found at http://www.freebok.net/help/velocity4.html the following  
example:
$sisyphus.pushRock()
## Velocity assumes I mean $sisyphus.getRock()
Its not discussed in detail what the author meant by his example, but I wonder 
how velocity assumes method calls.

Hello,

I try to put a key/value pair to a hashmap from velocity template.

First I put a new hashmap object into velocity context named "myMap".
In my templates I can write:
...
$myMap.clear()
Size: $myMap.size()
...
The above works fine. Now I want to put a key/value pair into the

hashmap using the method put(object, object).

So I wrote:
...
${myMap.put(["123", "test"])}

               ^             ^

...
And I get an exception: "${myMap.put(["123", "test"])} is not a valid

reference."

What's wrong?

Thanx Matthias
