configurations of Job properties of my jenkins plugin can not be saved

[roland ye]

Hi everyone,

    I am a newbie of jenkins plugin development.  I developed a class 
PolarionAlmProjectProperty extends JobProperty and deployed it to jenkins, 
when I typed any text in  polarionalm.regex and polarionalm.baseUrl 
editboxes in configuration form of a jenkins job, saved it,   and then 
reopened configuration UI, both these two editboxes remain blank, no text 
has been saved.  what wrong with source code ?
  
  Best Regards,
