whitespace validation??

[Sumithab Baskaran]

Hi All!

I am validating a text field which is an integer.

Here is the code:
<field property="dataFactoryFileId" depends="maxlength,integer">
<msg name="integer" key="fileSearchForm.dataFactoryFileId.integer" />
<arg0 key="fileSearchForm.dataFactoryFileId.displayname" /> <arg1 name="maxlength" key="${var:maxlength}" resource="false"/>
<var><var-name>maxlength</var-name><var-value>10</var-value></var>
</field>

When the user enters an integer like this: 2 0 9 6 9 5
Right now an error message is displayed: the field must be an integer.

How do I validate this and display an error message like - "do not use spaces while entering an integer"

Thanks in advance!

you need to write a custom validation using Regular expressions

Try swapping the two validations around so that it checks for a valid integer first. I have not tried it but I assume 2 3 4 is not a valid integer.

no custom validation necessary. use the 'mask' rule and check using this regex: ^[0-9]*$ .

oh, and the mask rule's error message can be customized to say whatever you want.

To avoid the extra spaces in submissions I use a Filter and RequestWrapper combination to trim all request parameter values. A submission of " " would get trimmed to "" and "88 " would get trimmed to "88". It really does the trick.

Note that my solution only takes care of leading and trailing spaces but the idea might help you to come up with a different kind of solution to the problem.
