I didn't solve it. I'm doing multi sites which it turns out Joomla does not support. My IT guy was sure he could do it because he's done it with Wordpress. Not Joomla though. We're going to install a 3rd party component instead; Virtual Domains or JMS2win Multi Site.
@VisPrada - I really appreciate your help, and also have to make it clear that I also use Google (for hours) to search for solutions before posting anything here. One of the strings that I used to search was "how to change default url home joomla 1.7" - but none of the links found was talking about 1.7 version.
But it's ok, I'll try some of the "solutions" and post which one had worked for me.
Until now, the only solution that seems to work is to change the JURI declaration in the code, but it seems so "forced", I mean, when you a change something in the code, specially something so essential like the variable that defines to "home" for the page, is a bomb waiting to explode.
I've configured ReRaplacer to change the link of the home-menu-item string, but it did have no effect. I also tried (as a desparate trying) to use the Redirect Component, with no luck.
The problem is not the link itself, but the option to say that the menu item is the Default Page. So, to change the link to what so ever, will not affect this behavior. Try, for instance, to set any other menu item as Default Page and you will see the result.
This "Home" thing is a pain in the nack and requires too much afford to achieve a so "simple" result. I mean, why in the hell don't we have the option to pin point "Home" as we want it in the Menu item and declare it as the "Default Page"? It's driving me crazy, to search and see so much talking and coding changes and stuff...
and I know that RT has nothing to do with it, once it is something related to Joomla itself.
So, I'll keep on searching, because this code changing solution is not the ideal one.
I've managed to do it. :cheesy:
The best (and right IMHO) way to do it was to put it in a module and show it as the main page.
What I had to do? Basically:
1 - I've duplicated my current template in the Template Control Panel;
2 - Created a new Menu (let's call it New_Home), that now contains the old Main Menu items (including Home itself, but with the option "Default Page" set to NO);
3 - In the Main Menu, I just left the "real" Home item, with the option "Default Page" set to YES;
4 - I've pointed all my modules, including the Main Menu Module to appear only at the "New_Home" Menu;
5 - The Flash animation had to be changed to point to the new "Home", saved and replaced by the old one;
6 - I've created a new module, that contains my flash animation, inside a centered table, and pointed it to appear only at "Home" (the Menu that only has Home set as Default Page);
7 - I also created a new CSS that do not contain any styling, so the Module would stick at the top of the page.
8 - The file Index.html that had the animation, was removed.
Now when I call the site, it loads Home (with the animation only), when the intro ends or I click on "Clique aqui para pular introdução" (that means "Click here to skip intro"), the new Home is loaded. If I click on the Home menu item, it stays in the page and does not go back to intro as before.
