I'm presuming it's the ActionServlet which converts the struts html:errors tag to the unordered list (ul) tag that is received by the browser.
I'm theorizing that if I could pass the line-item (li) attribute "list-style-type:none" to the browser, then with the removal of the list-item marker, the text would center within the cell.
So, how do I send an instruction to the ActionServlet that I want to specify an attributes value for li? Barring any incoming values, I suspect li just uses the default for list-style-type.
According to the ActionMessage API, one form of the ActionMessage constructor is:
public ActionMessage(java.lang.String key, java.lang.Object replacementValues) (or you can send a limited number of replacement values without the array).
I’m wondering if the "replacementValues" is the means to interact with the li html in the browser.
