Needs to dynamically include or exclude some fields during mapping.

[sanj...@gmail.com]

Hi,
    I have one requirement where in I need to dynamically map certain fields based on null or not null.  Currently dozer supports it with no control on it.  In other words, I can exclude it by specfying exclude-fields tag.  However my requirement is that i need to exclude it only if it is null.  Is there is any way this can be fine tuned. 

Note:-  By using map-null="true" or map-null="false" at class level or mapping level will not help.  Since by using this either i am placing null or ignoring the fields.  But in database it will update as null in case it dosn't have value.  So i want to ignore it some how.  Can any one suggest some technique or any way this can be worked out.

HI,

I have the same requirement. My beans attributes have a flag loaded set to true if the value if defined.

I use it to return partially initialized beans.

For the mapping, I'd like to filter out dynamycally the not-loaded fields .

What I'd need is an interface used to filter the fields to be mapped, and to provide the implementation for all the beans, or for a specific bean in the Dozer config.

Any solution ?
