Workaround for TechDivision Model (Germany Model Pdf)

1. Open the following file: app/code/local/TechDivision/Germany/etc/config.xml 

2. Edit the file to remove the following lines: 

<order_pdf_invoice>TechDivision_Germany_Model_Pdf_Invoice</order_pdf_invoice>
<order_pdf_items_invoice_default>TechDivision_Germany_Model_Pdf_Items_Default</order_pdf_items_invoice_default>
<order_pdf_items_invoice_grouped>TechDivision_Germany_Model_Pdf_Items_Grouped</order_pdf_items_invoice_grouped>
<order_pdf_creditmemo>TechDivision_Germany_Model_Pdf_Creditmemo</order_pdf_creditmemo>
<order_pdf_items_creditmemo_default>TechDivision_Germany_Model_Pdf_Items_Default</order_pdf_items_creditmemo_default>

3. Also remove the following line: 

<sales_order_pdf_items_invoice>TechDivision_Germany_Model_Pdf_Items_Bundle_Invoice</sales_order_pdf_items_invoice>

4. Save the edited file 

5. Refresh your Magento cache for the changes to take effect.

This will disable the Invoice Pdf functionality of the TechDivision Model extension, to use the Pdf Customiser functionality instead. All other functionality of the TechDivision Model extension is unaffected by this workaround.
