Support » Plugin: Gravity Forms Salesforce Add-on » [PATCH][2.1.1] Don't send empty fields to Salesforce

    It is tempting fate to send empty fields to Salesforce using the SOAP API. It can lead to type errors and extra complexity. This patch filters out empty fields before sending the fields to SalesForce.

    It should apply cleanly to 2.1.1, as long as this previous patch is applied:
