Hi George
I have a similar scenario, but the main difference is that I don't
know before hand the names of the query parameters.
I only have one page with this particular requirement so I do all the
URL query parameters encoding directly in the same page using the
events: DECORATE_PAGE_RENDER_LINK and DECORATE_COMPONENT_EVENT_LINK
Here is how my code looks like:
@OnEvent(EventConstants.ACTIVATE)
void activate(EventContext context)
{
filters = new ArrayList<Filter>();
decodeFiltersFromRequest(request);
}
@OnEvent(EventConstants.DECORATE_PAGE_RENDER_LINK)
void decoratePageRenderLink(Link link, PageRenderRequestParameters parameters)
{
encodeFiltersIntoLink(link);
}
@OnEvent(EventConstants.DECORATE_COMPONENT_EVENT_LINK)
void decorateComponentEventLink(Link link,
ComponentEventRequestParameters parameters)
{
encodeFiltersIntoLink(link);
}
private void encodeFiltersIntoLink(Link link)
{
if (filters != null) {
for (Filter filter : filters)
{
link.addParameter(filter.getAttribute().getId(),
urlEncoder.encode(filter.getValue()));
}
}
}
private void decodeFiltersFromRequest(Request request)
{
for (String parameter : request.getParameterNames())
{
// do not care about tapestry internal form parameters
// && do not care about page form parameters
// && DO NOT care about chenillekit's AbstractEventMixin
"value" parameter
if (!parameter.startsWith("t:") && !parameter.startsWith("f_")
&&
!"value".equals(parameter))
{
FilterAttribute attribute =
session.get(FilterAttribute.class, parameter);
if (attribute != null)
{
String[] params =
request.getParameters(parameter);
for (String param : params)
{
filters.add(new Filter(attribute,
urlEncoder.decode(param)));
}
} else {
// do something else
logger.error("weird request parameters names: "
+
request.getParameterNames().toString());
}
}
}
}
I hope it helps.
Cheers.
Alejandro.
