RE: Type converters: please help!!! :(
Posted by ravi_eze <ra...@ivycomptech.com>.
Thank you Jeff for the reply.
did u mean the *converter* attribute of the action tag that we give in
struts.xml? I didnt give any such attribute in it. I added
ActionClass-conversion.properties: in which i mentioned the attribute to
pickup a class which implements convertFromString and viceversa functions.
My action tag in the xml are as follows:
<struts>
<package name="eventsCreation" namespace="/event"
extends="struts-default">
<interceptors>
<interceptor name="..." class="..." />
<interceptor name="..." class="..." />
</interceptors>
<action name="oneAct" class="oneClass">
<interceptor-ref name="...">
...
</interceptor-ref>
<result>one.jsp</result>
</action>
...
let me know if you are looking for anything else.
cheers,
ravi

Ravi,
>From my understanding of OGNL, it *should* use the model object's conversion
descriptor. It's probably more surprising that it called convertFromString
without it. Are you using defaultStack?
I believe providing the model object's descriptor is the correct approach,
and you indicate that it's working. So why the long face? ;-)
