Hi,
I want to use type conversion feature to convert set of values to
a list in my action as mentioned in the type conversion documentation
(Advanced Type Conversion/Collection and Map Support) [1]. I followed
the steps but still no luck. I have few questions. (please excuse if
these questions are too naive , I am new to Structs 2).
i) Where should I put MyBeanAction-conversion.properties file ?
In the same directory as MyBeanAction.java
ii) Using the debug mode, can I check whether the
ObjectTypeDeterminer picked it ?
Yes, download the source code for Struts and XWork and you can trace
through it. I don't recall it displaying any useful debug messages in
the log.
I find this type "advanced" conversion very frustrating every time I
attempt to use it. Just try to keep it simple.
I always either use:
a Map, and reference each entry by its key (which is a string). eg
field['a'].value; or
a List, and reference each try by its index eg. field[0].value; and
make each entry a simple bean that doesn't require non-standard conversion
Finally ensure you have getters for the collections so OGNL can get it
before writing to it, and ensure it's a non-abstract type or instantiate
it yourself before the entries are set on it.
Also turn on devMode for your application.
Hope that helps.
