Hi All,

I am a self taught Java developer, and am very new to Struts. I've been working on a project for a while now and have tried to refrain from asking "newbie" questions, however, there is something that has eluded me for some time, which seems to be very simply. I am trying to default selected items in a checkboxlist. I have searched this site and read the numerous similar topics where solutions have been offered. Either I am going mad, I'm making a newbie error or am missing something vital.

So I hope someone will be able to help.

To summarise. I have a checkboxlist that is displaying a list of available Locales/Languages (which is retrieved from a SQL Table). I am trying to have some of these ticked by default. This is what I have:


This currently displays 4 checkbox's, none of which are ticked. And the HTML looks like this:

userManager - generated HTML

While they are not visible above, the "values" of the checkbox items above do indeed cotnain an underscore, so en_FI, en_DK, en_NO for example.

The function getLanguagesSelected is as follows (currently hard coded, just to get this to work):


Just to clarify, I have put a breakpoint in the above function and I know it is being called. So why doesn't it select the two checkboxes in my String Array?

Thanks in advance for any help you can offer.

Well, it was an embarrassing mistake!

The way I define my String Array on line 02 of UserActions.java is wrong! This would produce just one array item of "en_FI, en_NO" rather than 2 items.

If should have been:

Which actually makes everything work as expected.
