[SOLVED] Placemarks not visible

I've a curious problem, in fact I've made a map with some placemarks categories , in a first time they were displayed, now they are disappeared.
Maybe depend of the upgrade I made of component?

The page is amsrl.org/

Many thanks in advance

I can't understand, some time are visible other times disappear

Does anyone have a suggestion?

Hi.

You have the other extension, which uses window.onload ability to initialize.

In this case it overrides my initialize call.

Look at my docs

Hi Dmitry,
many thanks for your prompt reply.
I've followed your instructions in the link and now work very well.
I think a thank you is not enough, because your component and your assistance are great, so I will proceed with a small donation in your website.
It is a drop in the sea, but many drops can fill at least one glass
Have a nice week end

Thanks.
I'm very appreciate you.

And nice weekend you too
