Simple XML Parser XPath does not save when referring to an existing value

[nrichardson99]

While editing the XPath in a Simple XML Parser if you try to use the same xpath for two values, entering one after the other, it will not let you. You have to either close the advanced editor window and re-open then you can enter the desired value or you have to enter a different value move off the cell and then come back and change it back to the correct desired value. Appears the Vaadin combo box on change event holds on to the previous value to see if it has changed and thus doesn't think a new value was entered even though it is a new row. Not sure if this can be fixed at least not in the version of Vaadin Metl is using.
