ReplaceMarkerViewHelper

Dieser ViewHelper ersetzt in einem Textfeld enthaltene Marker. So kann man z.B. in einem RTE Feld den Eintrag ###time### mit einem Wert (timeUntilContinue) aus dem Fluid Template ersetzen.

<rsys:Format.ReplaceMarker marker="{ time: timeUntilContinue}">{workbook.textWait}</rsys:Format.ReplaceMarker>
