Hi, Can somebody tell me if there is another way to get this line of code to work properly? I get an 'equal sign expected error' because I try to 'nest' strut tags. <logic:equal name="changeItem" property="productName" value="<bean:write name="changeItemProduct" property="productName" /> "> I have two arrays, and I need to be able to check if the 2 properties in the two beans are equal so I could continue on with the iteration. If not, it should skip. Thanks!
You can't nest JSP custom tags inside custom tag attributes. The only way you can do what you're trying here is to either use a Java scriptlet along the following linesor to use a helper JavaBean which has references to your changeItem and changeItemProduct beans and exposes a boolean property. Both solutions are, IMHO, unsatisfactory. The underlying problem is that the Struts logic tag library is not quite flexible enough, in particular, it does not implement a full-featured expression language. Fortunately, these days we have a much superior alternative to the Struts logic tags: the JSP Standard Tag Library (JSTL). This is a standard library sanctioned by the JCP, has been much better conceived, and includes a simple expression language that will be part of the core platform in the next JSP version (2.0).Have fun, - Peter

The "changeItemProduct" is the duplicate definition. This is the same type of error you'd get in this code:
The solution is to change one of the id's. [ October 24, 2003: Message edited by: Junilu Lacar ]
