To cope with errors in code we can do many thing, among many approaches the most powerful is to use “try catch finally” block around the code that might cause trouble (one we know that it throws Errors) but what I have noticed working with different programmers common mistake is to use “try catch” block as a filter of errors.

Have you ever had mystery errors that your content stopped working without a reason? Possibly you haven’t registered all important listeners, most examples are simplified, i.e.
var image:Loader = new Loader();
image.addeventListener(Event.COMPLETE, onImageLoaded);
image.load(new URLRequest("myImage.jpg"));
More frustration every day:( I hoped to breeze through basic and core API but so far there are just issues, I have tried to use level method to pull single levels of category tree instead of receiving gigantic structure using tree method, but it was just beyond me. The level method when called without arguments should return top level category – works, then it accepts 3 arguments more to filter out the results, the website code, the store view code and parent category id, all according to documentation optional. But the method body…
/**
* Retrive level of categories for category/store view/website
*
* @param string|int $website
* @param string|int $store
* @return array
*/
public function level($website = null, $store = null, $categoryId = null)
{
$ids = array();
$storeId = Mage_Catalog_Model_Category::DEFAULT_STORE_ID;
$this->_fault('website_not_exists', var_dump($website));
// load root categories of website
if (null !== $website) {
try {
$website = Mage::app()->getWebsite($website);
foreach ($website->getStores() as $store) {
/* @var $store Mage_Core_Model_Store */
$ids[] = $store->getRootCategoryId();
}
} catch (Mage_Core_Exception $e) {
$this->_fault('website_not_exists', $e->getMessage());
}
}
elseif (null !== $store) {
// load children of root category of store
if (null === $categoryId) {
try {
$store = Mage::app()->getStore($store);
$storeId = $store->getId();
$ids = $store->getRootCategoryId();
} catch (Mage_Core_Model_Store_Exception $e) {
$this->_fault('store_not_exists');
}
}
// load children of specified category id
else {
$storeId = $this->_getStoreId($store);
$ids = (int)$categoryId;
}
}
//[...]

It’s been frustrating hour, I’ve been sitting and trying to figure it out why my call to sales_order.list doesn’t work, I thought “it can’t be” everything is fine (looks like) but it returns
faultCode=620 faultMessage=”Method “sales_order.list” does not exist”
Still didn’t gave up on this, following is the update on my progress. I have created in magento 3 types of roles, admin, read only and customer. I wanted to check what is the difference from the API point of view. I have browsed the documentation (rather a brief list then documentation) and have found in Magento Core API the “resources” method.
