I don't know if this is the right thread. But I just got multibox working
in my app (including preservation of checkbox entries between forwards).
Let me share with you what I have to see if this helps:
in Jsp: (cleanSolutionAreaTypes in an Application-scoped Vector)
<tr>
<td align="left">
Solutions Area*
</td>
<td align="left">
<logic:iterate id="solutionAreaType" name="cleanSolutionAreaTypes">
<html:multibox property="solutionAreaTypes">
<bean:write name="solutionAreaType" property="id"/>
</html:multibox>
<bean:write name="solutionAreaType" property="name"/><br>
</logic:iterate>
</td>
</tr>
in Form:
protected String[] solutionAreaTypes = new String[0];
public String[] getSolutionAreaTypes()
{
return solutionAreaTypes;
}
public void setSolutionAreaTypes(String[] solutionAreaTypes)
{
this.solutionAreaTypes = solutionAreaTypes;
}
What was causing me some exceptions was this. I originally used another
application-scoped vector called "solutionAreaTypes" for other purposes
(like drop-down lists). That Vector contains an entry that has a null ID
value (eg. name = "--specify--" value=""). This was causing Struts to throw
a non-intuitive exception. I then created another Vector without this entry
in it and everything seems to work fine now. Of course I've only gotten it
to work about 15 minutes ago so I'll let you know later if it really works
;-)
