@param jsPreFunctionBody
the body part javascript function
(without function declaration). It must
return true/false. This function will
invoke at client side before
{@code serverAsyncMethod}. If the
jsPrefunction returns true then only
{@code serverAsyncMethod} method will
invoke (if it is implemented). It has
implicit objects like {@code event} and
{@code source} which gives the reference
of the current tag. <br>
Eg:-

<pre>
if (source.type == 'button') {
return true;
}
return false;
</pre>

@param serverAsyncMethod
This method will invoke at server side
with an argument {@code wffBMObject}. The
{@code wffBMObject} is the
representational javascript object
returned by {@code jsFilterFunctionBody}.

@param jsFilterFunctionBody
The body part of a javascript function
(without function declaration). It can
return a javascript object so that it
will be available at server side in
{@code serverAsyncMethod} as
{@code wffBMObject} parameter. There are
implicit objects {@code event} and
{@code source} in the scope.<br>
Eg:-

<pre>
var bName = source.name;
return {buttonName: bName, author:'wff', dateOfYear: 2014};
</pre>

@param jsPostFunctionBody
The body part of a javascript function
(without function declaration). The
{@code wffBMObject} returned by
{@code serverAsyncMethod} will be
available as an implicit object
{@code jsObject} in the scope. There are
common implicit objects {@code event} and
{@code source} in the scope.
