  • SmartGWT 4.0 Upgrade with GWT 2.2.0 - Class Not Found

    Current we are running GWT 2.2.0 and SmartGWT 3.1 on Java 1.6 I am
    attempting to upgrade to SmartGWT 4.0. However when I execute the GWT build I get the following error.

    [ERROR] Errors in 'jar:file:/opt/opd/zfxb6work/drivers/smargwt/smartgwt.jar!/com/smartgwt/client/util/LogicalDate_CustomFieldSerializer.java'
    [ERROR] Line 3: The import com.google.gwt.user.client.rpc.CustomFieldSerializer cannot be resolved
    [ERROR] Line 8: CustomFieldSerializer cannot be resolved to a
    type

    I searched our application's GWT jars and the com.google.gwt.user.client.rpc.CustomFieldSerializer file does not exist.

    How do I resolve this issue without upgrading the apps GWT version at this time?

    It looks like you're using GWT-RPC in combination with an old version of GWT that did not support key APIs that *must* be present to avoid GWT-RPC incorrectly modifying dates during data transmission.

    Unfortunately you'll need to either:

    1. update GWT

    OR

    2. stop using GWT-RPC (which we strongly recommend against in general, for very very good reasons).
