Hi *,
I get a invalid url everytime I try the following:
App1 in mount_point "/foo" with mapped url "index"
App2 in mount_point "/bar"
Now I'd like to call url("index") in App2, but it does not work.
Is there a workaround, fix, bug?
Regards

The url/mapping works for a specific application hierarchy. And each application hierarchy is mounted to a specific mount point. So you can't access to the url mapper of different hierarchy. You can create app3 that would have app1 and app2 connected via /foo and /bar. So to make two applications to share the mapping they should be in one hierarchy.

Why are you trying to call rpc server function via "url" helper?

And calling url("/bar/index") doesn't work? It should if Bar is a
sub-application.
The URL helper can take an absolute path, provided that you're mapping
is set up correctly.
For example:
MyMainApp/SubApp1/show
MyMainApp/SubApp2/update
In the template of SubApp1::show, you can call url("/SubApp2/update")
provided that your SubApps are mounted correctly and mapper is properly
set up in each sub application.

Suggest you use mapper(value), instead of mapper(key, value) for
index-style pages. Saves typing and is more clear, imo.
ie. call to url("") will create a link to the root(the so called "index"
page) of the current application.

Hmmm, nope. Everything throws an exception. I have another problem with
mount_points but this is not the current topic. I will provide my
current mapping here:
main.cpp
> app.mount(...<dispatcher>...);
dispatcher.cpp

Tell me whats wrong. I'm not an expert in mapping, in fact I'm very
miserable.

I'd advise to call the application something else than Index because
it's not a good class name, and you're likely going to confuse everyone.
You need to setup your application hierarchy structure correctly. I
strongly recommend reading some of the cppcms examples (blog, forum).
Your main.cpp should be calling your Application like this:
app.applications_pool().mount(applications_factory<apps::MyMainApp>());
app.run();
MyMainApp::MyMainApp constructor should contain something like this
attach(new Foo(srv), "foo", "/foo{1}", "^/foo(/(.*))?$", 1);
attach(new Bar(srv), "bar", "/bar{1}", "^/bar(/(.*))?$", 1);

Unfortunately not.
Technically asynchronous applications can be unmounted during their life time so mapping can be invalid.
or new applications can be mounted.
What you can do it to do something like that.
class dummy_async_mapping : public cppcms::application {
dummy_async_mapping(...)
{
// all mapping (not dispatching) goes there
}
}
class async_app : public dummy_async_mapping ...
class sync_app : public cppcms::application {
sync_app(...)
{
attach("/webapi/" , new dummy_async_mapping()
...
}
}
Such that they both would get the mapping you need.

So, this will work? When I attach an async app in a sync context? The
last time I tried it like Petr suggested, it was mounted as sync.

I mean attach only small class that does mapping only (no dispatching). There is attach function that does only mapping for example. http://cppcms.com/cppcms_ref/1.0.0/classcppcms_1_1application.html#ab31985c608cfb176bbbf0958f438fbf7 So also it would be "mounted synchronously" it is just some base class for sharing the mapping, not actual dispatching.
