[Moose-dev] disappearing menu

Hi, i have a problem with the moose panel: when i load my stuff (MooseJEE) i have a group of database tables which has defined on top 2 visualizations. When i load a model form a MSE file, the first time that i click on that entity it is actually recognized has a TableGroup (see figure 1). When i click a second time on it it not consider anymore a TableGroup but just a MooseGroup, consequently i loose all the information specifically related with the table group (see figure 2). I define my group like this: mooseModel>>>allTables <navigation: 'All Data Base Tables'> | group | group := self allWithType: MJFAMIXTable ofGroupClass: MJFAMIXTablesGroup. group description: 'All Data Base Tables'. ^group SessionBeans group has the same definition but it works all the time. Any ideas on which could be the problem? Cheers, Fabrizio
