Magento Order status does not convert to Processing

Tinkering around to make a payment gateway integration for iPay88 took me some really significant time.
I've been using some method from paypal module to redirect the form to ipay88,
and does a re-query to ipay88 server to determine the approve of transaction from ipay88.
On done, created an invoice and saved the transaction for the invoice.
Payment paid appears correctly, but some how order status still remain "pending".
I realized that i did not set the cctransid to the payment in my controller, 
so one way to do it is to pass the TransId from controller to payment method model.
To do this, create a model class to accommodate values from request form passed in from ipay88,
then in payment method model capture function, retrieve the ipay88 returned model and setCcTransId(...).
When done, the order will now be shown as "processing", depending on the setting in the admin configuration for the payment status on payment.

Sample below:
//getting config saved in admin:
$aConfig = Mage::getStoreConfig("payment/Ipay88");
$merchantcode = $aConfig["merchantcode"];
$oResponse = Mage::getSingleton("Ipay88/Api_Response");
//convert data from postback of ipay88 into oResponse as object data
Varien_Object_Mapper::accumulateByMap($_REQUEST, $oResponse, array(
  "MerchantCode", "PaymentId", "RefNo", "Amount", "Currency", "TransId", "AuthCode", "Status",
  "ErrDesc", "Signature", "Remark")

//codes to requery ipay88 for actual transaction
if ($iPayResult == "00") {
  //update order status and payment status
 if ($oOrder->canInvoice()) {
  $invoice = Mage::getModel('sales/service_order', $oOrder)->prepareInvoice();
  if (! $invoice->getTotalQty()) {
   Mage::throwException(Mage::helper('core')->__('Cannot create an invoice without products.'));
  //below this will trigger capture in method model
  $transactionSave = Mage::getModel('core/resource_transaction')
Next, in the payment method model capture:
public function capture(Varien_Object $payment, $amount)
 if (!$this->canCapture()) {
  Mage::throwException($this->_getHelper()->__('Capture action is not available.'));
 $oResponse = Mage::getSingleton("Ipay88/Api_Response");
 return $this;
Sample of iPay88 Model to hold request data
class MercStudio_Ipay88_Model_Api_Response extends Varien_Object {
Yes, its an empty class which extends Varien_Object :) The Magic of Varien object is that it accept any data set to it (setVariablename(value) or setData("variablename", value)), and you may retrieve the data by calling getData("variablename")

jQuery .load complete did not fire

This happen when i was dealing with an upgrade from jQuery 1.5 to 1.7.2.
It took me some struggle to find out what happened, and finally, i found the issue.
It seems that the oncomplete function will not run if the document itself somehow contains javascript with syntax error in the script. It wasn't any problem for jQuery1.5, but for jQuery 1.7.2, it seems to halt execution after loading the content to the targeted dom.

MODx Return Error 400 in manager

The recent changes on MODx seems to create a new kind of error 400 on all the javascript used in the manager screen.
The problem comes from issue with minified index.php where it over replaced manager/assets with assets path, therefore doubling the path to the actual javascript file.
The solution have been resolved in the nightly build of MODx

Magento Export Sales Order Duplicate headers received from server

Its a bug which have been fixed in magento 1.7.
But for 1.6.2 users, you may change the core to fix this in:
app/code/core/Mage/Core/Controller/Varien/Action.php in function _prepareDownloadResponse:

By adding , true as the 3rd parameter in these lines:
->setHeader('Content-Length', is_null($contentLength) ? strlen($content) : $contentLength, true)
 ->setHeader('Content-Disposition', 'attachment; filename="'.$fileName.'"', true)
 ->setHeader('Last-Modified', date('r'), true);

Sencha Touch Carousel force slide

var carousel = Ext.getCmp("IDOfCarousel");; // .previous();

//to get active item
// but note that or previous will take time to animate and reflect.
//  therefor, to jump 3 slide away, just call 3 times and dont expect activeIndex to reflect directly after the call.

modx package management could not install

After dabling around on my new server,
i realize that the package installer did not work.
Further examination reviewed the error "package could not be found".

So i went into the core/packages and found that the extraction process did not complete.
After searching around, 1 way to work around it is to set under setting,
search for "archive_with" and change it to true.

Make sure to delete the package with "force deletion" and redownload and try install again...
hope it works for you... :)
