If you have
<html:text property="webdav.url" value="${config.webdav.url}"/>
in your jsp, then Struts (using BeanUtils) will try and do a get("webdav")
on your DynaActionForm so that it can then call set("url") on the bean
returned from the get.
So when you say "I checked and the property setter method for the
DynaActionForm in the example I cited is being called and the 'webdav.url'
string is being passed as the property name" - this doesn't seem right to
me. If it is being called then its not the Struts form population mechanism
thats doing it.
I'm guessing that in your struts config for the DynaActionForm definition
you have a property called "webdav.url" - if so then maybe its the form
initializtion thats setting "webdav.url" to null. If this is the case then
its never going to work this way. You need a "webdav" property that is some
kind of bean and then a "url" property in that bean and you somehow need to
have that bean set up in your form before the population is done.
If I'm completely off base here then you need to post more information - how
about posting the form definition from your struts-config.xml.
