Hello,
i Have this hashmap that i populate.
no when i want to show in a table the key : value i get an error. this is
the code:
....
#foreach($pageName in $myMap.keySet())
#foreach($dateDoc in $myMap.values())
<tr>
<td> $pageName $pageName </td>
<td>$pageName.getValue() </td>
<td>delete</td>
</tr>
#set($count = $count +1)
#end
#end
...
if i comment the second foreach i don't get an error, but i have nothing to
populate the date field with.
do you know what i am doing wrong here?
Thank you

New subject: [xwiki-users] get value from map
Hi,
My advice is to write the code in Java first and then adapt it for
Velocity. In Velocity you work with Java objects and you must know their
API.

I can't think of a reason to do this two nested loops. They are not
semantically connected.
<tr>
<td> $pageName $pageName </td>
not relevant
<td>$pageName.getValue() </td>
$pageName is the map key. What is its type? Does it have a getValue()
method?
<td>delete</td>
not relevant
</tr>
#set($count = $count +1)
not relevant
#end
#end
...
Also, when you post some code snippet and ask for help please post only
what's relevant. This is a good exercise for you: simply the code as
much as possible while preserving the error/misbehavior. By doing this,
in most of the cases you'll discover the problem yourself.

What is the error? How can we help you if we don't know the error?..
