You create a form in designer and provide it with a fixed form header (under the header tab of the form properties box).
Also you add actions in the action pane which label texts are computed using “computed for display” fields of the form in their formulas.
When refreshing the document all “computed for display” fields are being removed from the document in memory (check out the fields’ list in the document properties box while in edit mode before and after two refresh cycles).
After the second refresh cycle the actions’ texts are wrong because of missing field values.
This misbehaviour doesn’t occur if the document is being displayed in a frame of a frameset (because the fixed header of the form seems not to work in this place) or if the form doesn’t have a fixed header.
In addition all fields refering to “computed for display” fields placed in the defined fixed header area are having wrong results in their formulas after refreshing the document.
To correct this problem move the “computed for display” fields out of the fixed header area.
Removing the defined fixed header in designer causes the form to behave as expected in all cases.
If you need to define a fixed form header without loosing your action label texts you can switch your “computed for display” fields to “computed”.
