Bug in DynamicForm.validate validator type="isUnique"

[tampriscilla]

I found a bug in validation at DynamicForm validate() method.

NightBuild: builds/SmartGWT/12.0p/EnterpriseEval 2020-01-04

At DataSource:
<field name="STYLE_NAME" length="50" type="text" required="true" >
<validators> <validator type="isUnique"/> </validators>
</field>

TextItem nameItem = new TextItem("STYLE_NAME");
SC.say("validate:" + form.validate());
When I run form.validate() , it return true. However, the value is already exist in db and the form is actually showing error!

Please read the documentation for validate(). It will return true if local validation succeeds, you need to provide a callback if you want to know whether server-based validation (such as isUnique) succeeds.
