Null Value for RichWidgets\Input Calendar


We have an input Calendar box from RichWidgets\Input Calendar. 

We have set the dateformat as %d-%m-%y

We need that the input Calendar box shows no value when the date is null. So we have tried to use in the input the NULL VALUE as

and it does not work. It still shows a date....

We have tried to use #01-01-1900# in the NULL VALUE and it is giving an error. I suppose the fact that we have set the dateformat, disables the NULL VALUE in the input.... is there a way to prevent to show null dates for this case? thanks!

have you tried setting the Null Value of the input to NullDate() ?

yep. the same thing happens. Besides... nulldate() is the same as #1900-01-01#

Hi Jorge,

What do you mean by "Input Calendar box"?
I just set up the input calendar with your format and defined the input's NullValue as #1900-01-01# and everything seems to be working...


same here as Eduardo, see oml

Hi Dorine,

For me, it worked as expected (besides the fact that I don't see the prompt in your input).

But I am working with version 11, and it seems you both are working on an older version? 10? 9?
This may be a bug in an older version of Richwidgets, I don't know. 

This topic seems to relate to a similar problem, and the solution seems to be something like:

= True  

In input box extend properties.
You can try to see if it works.



mine is working, just added the oml for jorge to see how


Sorry :)
