Set all the missing values to $EmailTemplate/Content.
Just now I upgraded Email_Connector from 6.2.2 to 6.3.0, and updated DataWidgets: 0 errors. It is weird that your ACT_EmailTemplate_Save different, compared to the one of Email_Connector. Im Email_Connector it looks like this:
SUB_ValidateBodyContent like this:
ACT_EmailTemplate_GenerateAndSetPlainText like this:
What surprises me is that when downloading Email Connector and its dependencies i.e. Encryption and MX Model Reflection, it was not required to download Community Commons module.
I stuck now not able figure out why the html parameter is missing!
Could anyone shed some light on the cause of the problem or suggest a solution?
