Type converters: convertToString not called
hi,
We have Action class with Employee Object with setters and getters. The
Typeconverter was configured to be called when <EmployeeObject.empId> is
called by the jsp page. We found that convertFromString of type converter is
being called but convertToString is never called. Any idea why this is
happening? The details are as follows:
Type converter:
public class LongConverter extends StrutsTypeConverter {
public Object convertFromString(Map context, String[] values, Class
toClass) {
... ....
}
public String convertToString(Map context, Object o) {
... ....
}
}
in actionClass-conversion.properties located along with the class file in
the same package:
employee.empId=com.comp.util.converter.LongConverter
After some debugging we found that we need to add a new file:
Employee-conversion.properties in the same package of Employee class with
entries:
empId=com.comp.util.converter.LongConverter
and only then the convertToString would be called. I think we should have
only one conversion.prop file instead of 2. Any ideas why this is happening
this way? or am i missing any thing? please help.
cheers,
ravi

one more thing, then when would this method be called?? sounds like
redundant.

hi,
thanks for the reply. If the design had this behavior intended then probably
we cannot do any thing.... but in that case i would not agree with the
design. I read the post linked below and also the bug... but still unable to
understand the reason behind for such a design.
i think i will now have to redesign my application.
thanks for all your help

Re: Type converters: convertToString not called
Posted by jimski <ji...@gmail.com>.
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).

If it's a Long converter you might want to consider parsing a Long, not an
int.
That doesn't answer your question, but it still might be a good idea.

hi,
The code is as follows. Do not get terrified by the length of the post. I
tried formatting the post for better readability. Hope this helps you... to
help me ;)

public class newLongConverter extends StrutsTypeConverter {
public Object convertFromString(Map context, String[] values, Class
toClass) {
if (null == values || values.length == 0 || values[0]==null ||
values[0].trim().length()==0 )
return 0;
try {
int i = Integer.parseInt(values[0]);
return i;
} catch (Exception ex) {}
return 0;
}
public String convertToString(Map context, Object obj) {
if (null == obj)
return "0";
if(obj instanceof Long)
return ((Long)obj).longValue()+"";
return "";
}

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? ;-)
