1. I'd like to put the same code for e.g. regexp
form validation in one
page and just include it from other (ClassSheet) pages. Following
http://platform.xwiki.org/xwiki/bin/view/DevGuide/Creating+a+form+with
+validation+and+tooltips valdidation works fine, when
#macro(showallerrors) macro is included in ClassSheet page, though it
doesn't work, when macro in ClassSheet is included from other file (e.g.
putting macro in VelocityScripts page and writing in ClassSheet:
{{include reference="VelocityScripts"/}} or {{include document...)
It works though, if macro is put in ../xwiki/templates/macros.vm file.
Found it out
myself. Trick was, that include section should be before
velocity in ClassSheet. E.g.
{{include reference="VelocityScripts"/}}
{{velocity}}
...
2. As velocity cannot use passing variables by reference, I'd like to
create own "global" velocity variable similar to $isGuest, $hasComment,
$hasAdmin, etc. I tried to set this in xwikivars.vm, but it didn't
work.
Found that I can set value in cookie with Groovy:
{{groovy}}
import javax.servlet.http.*
Cookie mycookie = new Cookie("mycookie","myvalue")
mycookie.setPath("/")
mycookie.setMaxAge(-1)
xcontext.getContext().getResponse().addCookie(mycookie)
{{/groovy}}
and then I can get it as global value in xwikivars.vm
#set($myvalue=$xwiki.getUserPreferenceFromCookie('mycookie'))
And then I can get $myvalue from any other page.
