My comment is about Mutli Select Gravityforms field…
After looking into how the code of the plugin works I figured out that the plugin checks the type of the value and if it is “array” it applies the “gf_salesforce_implode_glue” hook implementation.
The problem though is that the type of the value of Multi select field is a string with the values separated by the “,” (not array). So the hook is never fired.
I did that with the latest version of GF (1.8.19) and the Salesforce Add-on (3.0.6.3) plugins.
