Hi,

I'm in DMS 2.3.0

In a dialog template, I have 2 dates. I wish to validate the fact that startDate is prior to endDate

I saw 2 solutions :

- Validators : but actually, I can use validators only in TextField. If I put a validator in CalendarField (validate=myValidator.class), the validator is not launched.

- Interceptors : in wiki, it is said that preInterceptor can be used to validate datas before saving. But if my interceptor detect that endDate is prior to startDate, how can I stop the save of the node ? and re-display the dialog template ? I'm not sure it is possible ?

Have I misunderstood one of theses solutions ? or is there a different way to do ?

Thanks,

Romain

Hello Romain

Here a solution that has been tested on eXo DMS 2.5, and should work on older release to.

1- Create an Interceptor that will be executed in "Pre-Save" to control the date

import java.util.Map

import java.util.GregorianCalendar

import javax.jcr.Session

import javax.jcr.Node

import java.text.SimpleDateFormat
import org.exoplatform.services.cms.scripts.CmsScript

import org.exoplatform.services.cms.JcrInputProperty
import org.apache.commons.logging.Log

import org.exoplatform.services.log.ExoLogger

import org.exoplatform.web.application.ApplicationMessage

import org.exoplatform.webui.exception.MessageException
public class MyDateControlPreNodeSaveInterceptor implements CmsScript{



private static final Log LOG  = ExoLogger.getLogger("MyDateControlPreNodeSaveInterceptor")



public SPGActuPreNodeSaveInterceptor(){

}



public void execute(Object context) throws Exception{ 

Map inputValues = (Map) context

GregorianCalendar today =new GregorianCalendar()

GregorianCalendar startDate = inputValues.get("/node/exo:startDate").getValue()

GregorianCalendar endDate = inputValues.get("/node/exo:endDate").getValue()

if(startDate.time >= endDate.time) {

throw new MessageException(

new ApplicationMessage("Start date must be inferior to end date", null, ApplicationMessage.WARNING))

}
}



public void setParams(String[] params) {}
}

2- Integrate this interceptor in your dialog code adding this following line at the top of the code

<% uicomponent.addInterceptor("ecm-explorer/interceptor/MyDateControlPreNodeSaveInterceptor.groovy", "prev") ; %>

 With this, the exception is raised and you stay on the dialog.

To introduce specific validators in the dialog.gtml, you could follow those steps:
1 / Implement the Validator interface
2 / Put the full path of the Custom Validatore class in the "validate" field.

For example, to add a validator "Float" for a field in the dialog:
1 / Implement this class:
package org.exoplatform.test;
FloatValidator org.exoplatform.webui.form.validator.Validator class implements (
....
)

2 / In my gtmpl, I use:

String [] nameArgs = ["jcrPath = / node / exo: test", "validate = org.exoplatform.test.FloatValidator"];
uicomponent.addTextField ("test", nameArgs);

==>
for further explanation, see this method :

org.exoplatform.ecm.webui.utils.DialogFormUtil.getValidator(String)

Yes, in ECMS, the method  org.exoplatform.ecm.webui.form.UIDialogForm.addCalendarField already use the "validateType" field, so I guess we have to open a new issue in DMS JIRA, to fix this in 2.5.x version.

Done
