Re: Weirdest Issue: HP PPM Table Component decreases row count by 1 on edit and save
I did find something which may apply to you but may not be easy to locate.
What you might try to see is if you have a field that uses a different batch but the same parameter as that of the TC-field in WB. If so, check if the field used outside of the TC has a rule configured in the request type to clear something if a certain action issaved.
You have a field 1 using batch 1, parameter one. This field is NOT in the TC.
You have a field 2 using batch 2, parameter one. This field IS in the TC.
If you now have a rule in the RT that sets field 1 to be cleared somwhere in the RT status dependency for a status, then when you step to this status, the rule will clear both fields.
There is a defect open for this but I cannot say if it is related or not. Have a look but if you are not sure or cannot locate such error, log a ticket with HP Support.
