Text Field CCE - Validation Java Class?

Hello,

Is it possible to use Java class to validate "Text Field CCE" widget using "Validation" tab?

We have a field that is using "Text Field CCE" widget. Under widget's Validation tab's "Rule:" it allows for a Java Class option, however the help text does not specifically recommend to implement any interface and says "Enter the fully qualified java package and class name used to calculate the default value...", which is kind of confusing for validation.

I found an interface I thought I could use called com.vignette.wcm.widgets.base.validation.IValidatable. I created and deployed a test implementation of it. After configuring it I got an error message saying something along the lines "missing validate() method". The interface's only method is "isValid()".

I do need to have java logic as I need to traverse previous versions of a content instance.

At this point I wonder if I can go this route at all?

Thank you,

Vlad

Hi,

This should work. Can you check the logs for any additional information?

You can find some CCE examples under <WEM_INSTALL>/Content/<VER>/extensions, for reference.

Thank you.

It does partially work the way I implemented. The reason for the "missing validate() method" error was the NullPointer in the logs. That NullPointer is the reason why I say "partially works".

I need to get to ManagedObject to perform logic with it and I saw in some decompiled code the following way to get it:

ManagedObject managedObject = (ManagedObject)context.get("CONTEXT_CURRENT_CONTENT_INSTANCE");

When I tried using it it returned "null". I inspected entire context object (passed to "isValid" method by framework) and found that that attribute is not there. The only two attributes there were CONTEXT_REQUEST and CONTEXT_WIDGET and they don't seem to have ManagedObject info.

I guess next step is listener rout?

You are right. The objects in the context are available only when accessed through the AppConsole.

Apart from the listener rout, a couple of options you could look at:

<![if !supportLists]>1. <![endif]>Implement a filter. See com.vignette.ui.core.editor.Filter. In the preSave you could throw an exception when the validation fails.

<![if !supportLists]>2. <![endif]>Another more extensive approach is to override the textfield widget, and provide your own validator to the widget or save handler to the CI editor. But it would also include adding your own action (in *actions*.xml), which the validator would need to call using AJAX. See the sample extensions (https://knowledge.opentext.com/knowledge/cs.dll?func=ll&objId=17821751&objAction=browse&viewType=1).
