strange DirectAction problem

All:

I have a very basic project set up to simply search our ldap directory. I used the JNDI Adaptor to reverse engineer our ldap directory and the model framework works great. No problems.

In trying to expand on the project and make it more flexible I moved the exact same search logic from Main.java into DirectAction.java. The only changes I made were to pass the search string from Main to my DirectAction. Now when executing a search I get the following exception on inetOrgPerson.mail().

</snip>

The exception happens whether I search for a valid inetOrgPerson or not - so even where no results would be expected.

If I leave the search code in my Main component it works fine and there are no exceptions. Does anyone have an idea that could point me in the direction of figuring this out? What seems strange to me is that the model framework seems to be expecting different results under the two scenarios. I'd really like this to be a direct action so that I an easily have our webmaster call it from our school's site as a whole.

thanks in advance for any wisdom,

Tim
