Several Data Provider + Personalization Template + variable screen

Hello,

We have a <i>complex</i> problem, this is our situation:

one template with 3 data providers (3 tables) with the same initial variable (month/year) in only one textbox (melt_variables=X).

When we personalize the template and reload it we enter to variable screen (variable_screen=X),

but the variable is not applied to all data_providers/tables, only the first one is changed.

Is there any incompability between several

data_providers + personalization + variable screen.

Thanks in advance,

albert
