GSP- formatDate tag issue handling null date

I used a collection of DATE field from Controller to GSP using the tag - But at times there are blanks and invalid data and it throws up an error. How should I handle this NULL pointer??

Code < g:formatDate format="yyyy-MM-dd" date="$ {objectInstance?.expiryDate} "/>

I also tried using this -- ${objectInstance?.expiryDate?.format("MM/dd/yyyy")} , but no luck. Thanks in Anticipation.

in the GSP you can also use formatDate in this way:

${ g.formatDate(format:'yyyy-MM-dd', date: objectInstance?.expiryDate ) }

when objectInstance?.expiryDate is null it will just render a blank instead of returning an error

Vignesh,

Here are a couple of potential solutions (assuming that you would be ok with showing nothing or some alternate text when the date is null):

${try{objectInstance?.expiryDate?.format('MM/dd/yyyy')}catch(e){''}}

Or, you could handle this in the controller (my preferred method) using the same code as a above without the ${} wrapping it and set it into a model property.

[expiryDateFormatted: try{objectInstance?.expiryDate?.format('MM/dd/yyyy')}catch(e){''}]

Give those a try and see if they will work for you.

After speaking with Vignesh it turns out that expiryDate is actually a string and not a date. Below is a solution that would work for a string value.

${try{new Date().parse('yyyy-MM-dd', objectInstance?.expiryDate).format('MM/dd/yyyy')}catch(e){''}}
