The reason I am using a template is that there is a select box on that wiki
page and some information needs to be fetched based on the value user
selects.
To be able to use the value selected by the user, I need to do an HTML Post
first.
so, I submit the form and the values are processed by a template and now I
need to display the value calculated in the template, on my xwiki page.
To display some values passed to a wiki page (either with a GET or a
POST) you can do the following :
$request.myfirstvaluekey
$request.myfirstvaluekey
If you have a set of values that are passed under the same key you can do :
$request.getParameterValues("mymultiplevalueskey")
I tried some stuff but did not work. So, now I am
actually creating an
object on that page and set its properties with the value calculated in the
template.
any other better way of doing this?
Doing it without a vm template I guess.
Is it possible to access the selected value on the
wiki page without doing
a post?
what does $!{value} provide...I do not understand the ! before the variable
name.
The default velocity is to print the call if it returns null, for
example if you put $mynonexistingvariable in a wiki page it will be
displayed, the ! is meant to avoid this default behavior,
$!mynonexistingvariable won't print anything in the rendered page.
On another note:
In the object solution for this problem, I try to set the object property
(of type Number) with a velocity variable which also has a numeric value.
when I save the document after setting the object values, it gives me an
exception on the "save" method.
Error number 3201 in 3
Wrapped Exception: java.lang.Integer
I checked the type of Number for that property and changed it from long to
Integer in the class editor but, it still gives this error.
I am also setting a boolean value in the object. I noticed that the boolean
fields take values 0 or 1 but display them as No or Yes.
So, when we "get" we get Yes/No and when we "set" we have to set 0 or
1.
could that be causing the exception?
I ma not sure what is causing this exception. but when I hit the back
button, I see the values of the object properties set appropriately and
displayed. Only when I do the $response.sendRedirect with "save", it throws
the exception.
Do I need to use Util.parseInteger or Util.toNumber in any of these cases
(before setting the Object property value to a number)
Can you paste your velocity snippet here with the details about the
types of the properties used in it ?
