Hi, everyone.
This is my first post so I will try to make it short. I am trying to
use the logic:iterate and html:multibox. I found what I thought was a
good example through a google search, but I just can't get it to work.
Here is the exception I get: javax.servlet.ServletException: Cannot
find bean unit in any scope I understand the error, but don't know
how to fix it.
The example I am following said to setup the tags as follows:
<logic:iterate id="unit" property="bannerUnits">
<html:multibox property="selectedUnits">
<bean:write name="unit" property="unitID"/>
</html:multibox>
<bean:write name="unit" property="name"/>
</logic:iterate>
My form for the jsp in the struts-config.xml is bannerFeedForm.
bannerFeedForm has a bannerUnits array of the type Unit and a
selectedUnits array of the type String. I populate the bannerUnits
array from a db query in the action. If you need the form code or the
relevant action code, let me know.
I believe my problem is that the id attribute of iterate is looking for
a Unit bean in the page scope. However, the only bean in scope at the
time is the bannerFeedForm. I figure I am missing something here, but
am not sure what. I tried the following changes with the same results,
of course.
<logic:iterate id="unit" name="bannerFeedForm" property="bannerUnits">
<html:multibox name="bannerFeedForm" property="selectedUnits">
<bean:write name="unit" property="unitID"/>
</html:multibox>
<bean:write name="unit" property="name"/>
</logic:iterate>
Should id be set to something else? If not, how do i get the needed
bean in scope? In all the programming up to now we use
request.setAttribute to pass information to the jsp.
I am really a newbie at this and can't spend much more time trying to
get it to work. Another programmer suggested just hardcoding all the
checkboxs, but I hate hardcoding something when I know I should be able
to do it dynamically. Any help to avoid this would be appreciated.
