Hi Ravi- I think the problem here is how the struts2 tags were implemented. As far as I can see from the code base the type converter definition you're referring to is used by the XWork API and not OGNL. The XWork api is used by the Struts Tags which have the option to call the converter or not. In the case of rendering content, the option chosen by the designers is not to call the converter and call toString() instead. Check out this bug report https://issues.apache.org/struts/browse/WW-2047 for more details.
I asked a question about this: (http://www.nabble.com/Struts-framework-design-question%3A-Type-Converters-and-Tags-to15019888.html) ...and it seems like a community generated patch is probably the only way forward at this point. I started looking into it, but my day job has been way too busy to give me any time to actually code a patch. There's also a question on my part as to whether or not the patch would even be accepted given that 2.0.6 supported type conversion at render time and the core struts2 dev team has explicitly chosen to remove this feature (as mentioned by Don Brown in the referenced bug report). ravi_eze wrote: > > hi, > > We have Action class with Employee Object with setters and getters.
