AJAX tags do not handle params properly for Prototype library

PrototypeProvider.getAjaxOptions() in JavascriptTagLib.groovy should be modified to allow params as a map, rather than requiring a string (but still provide support for the string).

the line:
ajaxOptions << "parameters:$

"
should be replaced with:
def params = options.remove('params')
if (params instanceof Map) {
ajaxOptions << "parameters:'" +
options.remove('params').collect { k, v -> "$

=$

" }.join('&') +
"'"
} else {
ajaxOptions << "parameters:'$

'"
}

To do the same functionality in DojoProvider, it seems that you would replace the following in doRemote():
attrs.params?.each

with:
if (attrs.params instanceof Map) {
attrs.params?.each

} else {
out << ",$

:''"
}
