RE: OGNL expression help
Could someone show me the correct way to insert a string
field length into
the size attribute of a s:textfield element.
s:textfield name=firstname maxlength=15 /
I think he was looking for something more involved,
something like:
s:textfield name=firstname size=%{myString.length()} /
I have not tested code to do this, so I don't know if
that would work. Also, what if the myString is null
or an empty string. The code would throw a null
pointer or the field size would be zero.

LOL :) I suspect that my difficulties in trying to use OGNL to insert the
length are related to the fact that the method call on a string is
String.length() not String.getLength and when I use size=%{attrib.length}
OGNL is trying to call getAttrib().getLength() on my action -which won't
work.
So, rephrasing slighly, how do I/can I use OGNL to call methods on
attributes in my actions that do not follow the Bean pattern.

You could create your own MyString class that
extends String and then have a getLength() method
that calls super.length().
It's a pain, but should work.

RE: OGNL expression help
Extending String? String is final so it isn't doable ;-) I did not check that. I see someone posted a better solution than this but I guess if someone wanted to have a getLength() for a String, they could write a container class that holds a String and then implement all the methods to call the corresponding String methods. That would be really be a pain! Anyway, thanks for the clarification, Neil -- Neil Aggarwal, (281)846-8957, http://UnmeteredVPS.net Host your struts app on a CentOS VPS for only $25/month!
