Extbase AJAX call only works in some Actions - ajax

Question

While I managed to get a working AJAX call, it won't works with my already created actions, not on a newly created one.
My Typoscript looks like this:
lib.AJAXPrototype= PAGE
lib.AJAXPrototype {
typeNum = 896571
config {
disableAllHeaderCode = 1
xhtml_cleaning = 0
admPanel = 0
debug = 0
no_cache = 1
additionalHeaders = Content-type:text/html
}
}
AJAX_Plugintyp < lib.AJAXPrototype
AJAX_Plugintyp {
typeNum = 89657201
10 < tt_content.list.20.myext_myplugin1
}
My AJAX call looks like this:
$.ajax({
url: "index.php",
data: "tx_myext_myplugin1[controller]=Mycontroller1&tx_myext_myplugin1[action]=ajax&type=89657201",
success: function(result) {
alert(result);
}
});
My ajaxAction:
/**
* action ajax
*
* #return void
*/
public function ajaxAction() {
$test = 'sometext';
$this->view->assign('test', $test);
}
My Ajax.html (View/Output):
<f:section name="main">
<f:flashMessages />
<div id="ajaxd">{test}</div>
</f:section>
I won't get anyoutput from this, I created this Action just for the Ajax Output. However, if I use any other controller/action combination, it works!
What could I possibly have done wrong with the new Action?

Answer 1

Two things about ajax and Extbase
First Placing JS directly in the view often fails, because Fluid is trying to parse JavaScript's arrays as own array/variable. Very uncomfortable. Solution is placing JS in separate files (therefore I asked you a question about this). See this question/answer
Second thing is Firebug (or other similar tool). With ultra long paths of Extbase links it's easy to make some annoying mistake in it, and then you need to compare carefully char by char.
Firebug will help you to find AJAX problem really fast, just open it switch to the Net tab and then you'll see what is sent with ajax after some action and what it returns. Most probably you were receiving something like:
Uncaught TYPO3 Exception:
The action "xxxxx" (controller "Yyyy") is not allowed by this plugin...
But the only way to check it is debugging with Firebug :)

Okay, so RIGHT NOW it works.
This might sound crazy, but I didn't really change anything for it to work.
I did forget to add it to the ext_localconf.php:
Tx_Extbase_Utility_Extension::configurePlugin(
$_EXTKEY,
'Myplugin1',
array(
'Mycontroller' => 'list, ajax',
),
// non-cacheable actions
array(
'Mycontroller' => 'list, ajax',
)
);
However, I did this yesterday and afterwards, it didn't work. Today I tried some random editing in the typoscript again (changing pagetype etc.) and suddenly it worked! However, I went back to the exact state I had yesterday and it still worked.
I'm confused, no idea if I just had to rearrange the typoscript or if it had to write it again for some reason, but I'm happy it works now!
