[Form-modeler] What's the correct way to use Functions in formmodeler

[wguo]

Hi ,

    I want to add a check on my input which don't allow include some special chars , as the tip said i can use Functions class , so i write the

    =Functions.String.containsNone({$this}," ")  in pattern filed . But after that , it always report error even the value is correct .

    So is there any wrong when i used the Functions ?

Thanks !

And the Regular Expression looks not work too . When i set  ([\\S])*  in the pattern field , it always report error .

When i checked the code :  https://github.com/droolsjbpm/jbpm-form-modeler/blob/6.1.x/jbpm-form-modeler-core/jbpm-form-modeler-service/jbpm-form-modeler-ui/src/main/java/org/jbpm/formModeler/core/processing/fieldHandlers/InputTextFieldHandler.java

should be this part :  if (!"".equals(paramValue[0]) && expr != null && !"".equals(expr) && !paramValue[0].matches(expr))

But when i test my regex in java code , it runs ok :

"testspec ialchar".matches("([\\S])*")    false

"testspecialchar".matches("([\\S])*")     true
