Re: Error Struts 7

I want to add some comments here about the somehow misleading documentation o=
n this.
>>
Files Number Limit

Since Struts 6.1.2 a new option was added, which uses Commons FileUpload fea=
ture to limit how many files can be uploaded at once, in one request. This o=
ption requires to use Commons FileUpload ver. 1.5 at least and by default is=
 set to 256. Please always set this to a finite value to prevent DoS attacks=
.
To change this value define a constant in struts.xml as follows:
<struts>
    <constant name=3D"struts.multipart.maxFiles" value=3D"500"/>
</struts>
<<
=20
Today, I used=20
<constant name=3D"struts.multipart.maxFiles" value=3D"3"/>
because I have 3 file upload tags on my mask.
But the application crashed, even with only one file upload,  till I found a=
 debug message in wildfly server.log
