I'm currently migrating an app from Struts 1.x to 2.x and encounter this
situation where I was calculating the tabIndex of a JSP on the fly
(reusable JSP). In struts 1.x this was done using
<c:set var="tabIndexCount" value="<%= request.getParameter("foo") %>"/>
...
<html-el:text tabIndex="${tabIndexCount + 1}" ... />
According to the Struts2 documentation, non-string attributes are
evaluated as expressions, so the following:
<s:textInput tabIndex=""%{#request.foo + 1}/>
should do the work, but instead the above code is *appending* a 1
(string concatenation). Am I missing something or this is a bug? Any ideas!
