There are two approaches to correcting this.
1. If you are using Sessions, Place the datalist into the session instead of the request. This will insure the datalist is available, but can does add overhead to the application. Additionally, if you do not clean up the data, this can use up memory
So long as the Action class is performing a truly generic function then I see no problem with this. Additionally, the name of the Action should reflect the function that is being performed. For example, if the action is forwarding a bean embedded in the form to a web service, the Action should
I would name the actual action based on the functionallity:
This would indicate that you are running two seperate web pages that both attempt to post data to a web service. The process for posting these requests are identical an therefor redundant to create two independent action class
In 1.2.7 you simply change the ActionErrors to ActionMessages. you still save the errors with the saveErrors method and it works the same in the tags.

Yes, the validate method is going with the ActionMessages as well. However, the Validator Plug-in is something that should be looked at. It is a little more object based in nature so you do not end up repeating the same validations on multiple forms. It returns errors in the same mannor as the

This is dependent on how you have structured you database query. There are multiple solutions to what you are attempting to do.

I would recommend changing the capital T to a lowercase t. This is standard. I have had problems in the past with having uppercase variable names. This is due to the reflection that Struts uses to find associated getters and setters.
