ListGrid.exportData() gets NullPointerException

[jay.l.fisher]

After updating my project with the latest SmartGWT.jar (Nov, 9 nightly build) I am getting an exception when trying to export grid data as csv. I haven't changed my code that invokes the exportData() method and it is just a call to exportData() with no other parameters or export related properties being set.

This stack is not possible with the code as it stood on Nov 9th, but it does match a problem fixed a couple of months ago. Check over your environment to be sure you are not using stale files - perhaps a duplicate classpath entry or similar problem.

Do I need both smartgwt.jar and smartgwtee.jar? That is probably what I've got wrong. If I remove smartgwt.jar where can I find the latest version of smartgwtee.jar?

[smartgwt.dev]

You need to latest server jars. smartgwt.jar and smartgwtee.jar are client (GWT) side jars and do not need to be deployed to the server.

Where do I get the latest server jars?

Definitively fixed in smartgwt ee 1.2.2. Thanks!

I have to add my kudos to the many others in these forums. I continue to be amazed by your exceptional software AND how responsive you are to questions asked in these forums. Thank you!

When I follow the download link for SmartGWT EE I get a 1.2.1 version. Where can I get 1.2.2? This is where I am looking:
