http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/basicportal/bP/WEB-INF/src/war/org/apache/scaffoldingXPress/base/SimpleBean.java
for simple search cases, so I just CVSed.
I will add a search example to scaffolding, and a search chapter to my new book(preview in less than a month), and add searching to the labs.
more inline.

You submit search to the action, with search bean populated. (not much use for a basebean code here, I think you are saying) ListEmployees has a page, action, bean. It needs to receive in (session?) scope (or url properites) the search arguments in the action only. based on it, it populates the bean and page displays it.Well weird probably isn't the word:) At some point I have to pass the parameters to IBatis based on these parameters bundled in an Object. So what is first happening is my SearchFormBean gets populated but then I'm stripping the properties out in the Display action... ProjectSearchBean searchBean = (ProjectSearchBean)ae.getSessionBean("projectSearchBean"); ArrayList projectIds = projectSearchBean.getProjectIds(); String someOtherVar = projectSearchBean.getSomeOtherVar(); //now populate based on search params above projectFormBean.populate( projectIds, someOtherVar );
Looks good to me.
I see now. I like the first thing better.So what I didn't like was that now projectFormBean.populate( ArrayList projectIds, String someOtherVar ) ends up calling the DAO doRetrieve( ArrayList projectIds, String someOtherVar ) which ends up having to put the variables back into some Object again so that it can be passed to IBatis. The reason I found this weird (annoying would be a better word) is that intially everything already is in an Object (ProjectSearchBean) - it seems so much easier to just call projectFormBean.populate( projectSearchBean.getMap() )
I just do not like DAO knowing beans(complex objects), vs just simple strings, collections, etc.
Just a personal preference. Else you have to import struts into DAO.
I like to keep layers seperate.

vs having to pull out all the variables from projectSearchBean in the Display action, only to put them all back into an object later in the DAO.
