I'm trying to pass parameters via URL to a multi-picklist field, but I'm finding that it seems to be impossible to build a pageRefence with non-unique parameters.
pageRef.getParameters().put(00Ne0000001cwJ4, 'value1'); pageRef.getParameters().put(00Ne0000001cwJ4, 'value2');
becomes this in the URL: &00Ne0000001cwJ4=value2
Even doing something like:
where you've built the full URL that includes the parameters yourself will still end up stripping the additional values. Are there any workarounds to this?
