So far this is what I have done:
1) Installed the module: Settings->Modules, search webkit, install report_webkit
2) Add Webkit Logo: Settings->Technical->Webkit Logos
Create and add custom png logo
3) Alter Webkit Headers/Footers: Settings->Technical->Webkit Headers/Footers
Change to Letter Format
4) Edit Company Data: Settings->Company Logo
Webkit tab: Add logo, Add Headers: select Base Sample
5) Change Invoice to webkit: Settings->Technical->Actions->Reports, Search for Invoices
Edit
Enter "webkit" into Report Type field (originally pdf)
Deselect "Add RML Header"
Select Webkit Tab (appears after Report Type is changed)
Set Webkit Header to: Base Sample
[After my first few rounds with the the print issue I also coppied the demo Mako webkit example into the "Webkit Template (used if Report File is not found)" field, and I also enabled webkit debug]
Going to invoice and hitting print now throws up:
OpenERP Client Error
Uncaught SyntaxError: Unexpected end of input
Setting the invoice report back to pdf returns functionality.
Now, I do not know if the problem is whether wkhtmltopdf is missconfigured on the SaaS server, its PATH is not set on the host, or if I am doing something else wrong. Would really appreciate any input or ideas on solving this as custom output is needed and the SaaS documents do not seem to exist for webkit.
Does anyone know if this is going to be addressed/fixed in Version7.SaaS3 or do we need to wait for the Online Odoo to change to Version8.SaaS?
