Re: [xwiki-users] Your ideas to save number in custom object using Groovy code?

[Valdis Vītoliņš]

Investigating
http://platform.xwiki.org/xwiki/bin/view/DevGuide/DatabaseSchema and
trying other number formats got it working for float (xwikifloats
table).
Groovy code:
..
Float daudzums
daudzums = Float.parseFloat(string)
...

Actually I need only integer eg 11 in place of 11.0 but this is minor
issue.
I suspect there is some misuse between int and Integer for integer
types.

[xwiki-users] Your ideas to save number in custom object using Groovy code?

[Valdis Vītoliņš]

I'm trying to save custom object values, and can only for strings using
advanced script from
http://platform.xwiki.org/xwiki/bin/view/DevGuide/GroovyNotificationTutorial 
For Number type (tried integer and long), I couldn't save value in any
way. Tried explicitly define as 
int daudzums
and 
daudzums = Integer.parseInt(string)

I exhausted my ideas and would like to get some more :-/
