instead of
#set($fieldValues = $row.getFieldValues)
try
#set($fieldValues = $row.getFieldValues())
I think velocity needs the () at the end of a method call such as
key.toUpperCase()

Subject: How to handle the nested Loop
I have in velocityContext a Hashtable. The key is String type and value is
a ArrayList.
The arraylist holds number of java beans. The each bean has a method
getFieldValues(), which returns an array
String[ ]. Now I try to print out each String value in the String[ ]
array. I tested in java code to print out the value in the array; but in
my velocity template, I can't print anything. I don't know why. I don't
even know if this is the correct way of doing these nested looping.
#foreach( $key in $OFFENDIGN_ROWS.keySet() )
---------------> get key
#set($upperKey = "${key.toUpperCase()}")
<a class="large" name="${key}" id="${key}">${upperKey}</a>
TABLE border="1" width="100%" cellspacing="0">
#foreach( $field in $BEAN_FIELD_NAMES )
<TH class="highlight">$field.Property</TH>
-----------------> This is ok
#end
#foreach( $rows in $OFFENDIGN_ROWS.get($key) )
-----------------> get the arrayList associated with key
#foreach ($row in $rows)
------------------> get bean in the list
#set($fieldValues = $row.getFieldValues)
------------------> get the String[ ] array of the bean
<TR>
#foreach( $fieldValue in $fieldValues )
-------------------> get the String value from the array
<TD> $fieldValue </TD>
--------------------> display nothing
#end
</TR>
#end
#end
</TABLE>
</p>
#end
Did I do something wrong? Thank you.
