Notes

Simple example of providing a custom validation handler using SSJS. When the length of the submitted value is greater than expected, an error message is queued in the FacesContext. The validator state is then set to invalid which causes the XPages Request Processing Lifecycle to failover during Phase 3: PROCESS_VALIDATIONS.

<xp:inputText id="inputText2">
	<xp:this.validator>
		<![CDATA[#{javascript:
			var sv = this.getSubmittedValue();
			if(sv.length > 3){
				var msgStr = "way too long!";
				var msgObj = new javax.faces.application.FacesMessage(
				javax.faces.application.FacesMessage.SEVERITY_ERROR, msgStr, msgStr);
				facesContext.addMessage(getClientId(this.getId()), msgObj);
				this.setValid(false);
			}
		}]]>
	</xp:this.validator>
</xp:inputText>
<xp:message id="message2" for="inputText2"></xp:message>
