Add one day to a binding

Question

Hi all,
I assume this is a very dumb question... How can I add one day to a date that is like this :
#{bindings.ChooseDateCrah.inputValue}
It's a binding in a the header text property of a column.
That : #{bindings.ChooseDateCrah.inputValue + 1} or that : #{bindings.ChooseDateCrah.inputValue} +1 does not work.
Thanks.
Frédéric.

Hi Frédéric,
Yeah, you cannot apply a converter on the headerText attribute of a column. However, you can instead place an outputText in the header facet of the column, then the converter option still works.
As for the code, no, in the RowImpl object in the getter method of your calculated attribute. (That method is quite complicated for a read only value though).
You can check my reply at Re: How to access menbers of the current row of an af:table component? as for how to create a custom converter. In your specific case, however, you would have to extends DateTimeConverter and decorate the getAsObject and getAsString methods in order to add one day before calling super.getAsString and remove one day from the returned value of super.getAsObject before returning to ensure reversibility.
A managed bean solution would imply the use of the implements Map EL hack which is both easy and hard, depending on your experience level with JSF and EL.
