Are you sure it is undo that is restoring the styles ?
If so then was the undo manager suspended when the styles were applied ?
If you don't want any styling changes to be included in the undo / redo operations at all and are only interested in plain text changes then the easiest is to apply a plain text undo manager.
textArea.setUndoManager( UndoUtils.plainTextUndoManager( textArea ) );
Alternatively if you're using the CustomeStyleArea template/framework I provided then change the following line in the constructor:
super( "", CustomStyleArea::styleParagraph, MyStyle.NONE, CustomStyleArea::styleText, false ); // added false for plaintext undo

@Jugen Thank you very much for your answer. I found where old style comes from - this.setUndoManager(UndoUtils.richTextSuspendableUndoManager(this, suspendUndo))
. When I comment setting this undo manager then problem disappears. I tried to add false
to super constructor - super(....., false)
but it didn't help. At the same time there is no UndoUtils.plainTextSuspendableUndoManager()
.

@Jugen Maybe I can try to add UndoUtils.plainTextSuspendableUndoManager()
? What do you think?

Hmmm, I don't think I was clear enough with the change to the super constructor invocation. When changing it you MUST also remove setUndoManager
from your code as well as the suspendable code as they are not needed anymore. Then the undo manager will only keep track of plain text changes and NO styling changes.
