[JXTemplate] - null Date Object throw
java.lang.IllegalArgumentException
Hi:
I am trying to show some Dates fields retrieved from a DB. This fields can
be NULL (a user still does not fill the field). I wrote the following code
to present the field:
<td><jx:formatDate value="${item.pac_fecha_ini}" pattern="MMM/yyyy"/></td>
The problem is when the @value is null, then it throws the below
exception. I clearly understand the cause of the Exception.
But is this OK? Need I check the values before using the <jx:formatDate>?
or we can change the <jx:formatDate> to check for null and return a empty
String in case it does not exist?
WDYT?
Best Regards,
Antonio Gallardo

Re: [JXTemplate] - null Date Object throw
java.lang.IllegalArgumentException
Posted by Antonio Gallardo <ag...@agssa.net>.
Hi:
Continuing my monolog. I wrote this function as a workaround of the problem:
<jx:macro name="showDate">
<jx:parameter name="myDate"/>
<td>
<jx:choose>
<jx:when test="${myDate.toString() != ''}">
<jx:formatDate value="${myDate}" pattern="MMM/yyyy"/>
</jx:when>
<jx:otherwise>
N/A
</jx:otherwise>
</jx:choose>
</td>
</jx:macro>
Hope this help somebody else.
Can JXTemplate have this built-in as part of the <jx:formatDate>?
Best Regards,
Antonio Gallardo
