            Bug ID: 138242
           Summary: Editing Forms in base: Controls are disappearing after
                    doing many attribute changes during fine design of
                    Base form
           Product: LibreOffice
           Version: 7.0.3.1 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Base
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: rich.libre at demattio.co.at

Description:
after a longer time of editing a form, the controls disappear and the form is
damaged. I will provide the database with the damaged form.

meanwhile it happened four times and the result of work is lost.
It is impossible to reproduce. I only can say, that it happens after many (100
or more) changes of attributes in Controls of a form.

Steps to Reproduce:
1.impossible to reproduce step by step. do many changes during a longer time.
2.
3.

Actual Results:
*) in the forms navigator all controls and subforms are present.
*) it is also possible to select the hidden controls 
   - example grid coordinates (x / y) = (10.0 / 0.9)
*) selecting the visible controls are making the respective control 
   in the forms navigator selected too
*) selecting the invisible object (10.0 / 0,9) does not select an object in 
   the forms navigator
*) the invisible objects do no longer have attributes for coordinates and size
   shown in control properties window - the visible do have them
*) selecting "position and size" from the contex menu of the invisible objects
   are showing the correct coordinates.
*) conclusion: it looks like the hidden objects did loose their identity 
   as a control in a form and behave the same way, for example a rectangle 
   would do, If I add it by using the normal drawing tools.

Expected Results:
Forms not going to be damaged


Reproducible: Sometimes
