IllegalArgumentException: MetaClass not found

dalemccut · January 7, 2021, 2:34pm

The following is the xml from key-edit.xml is creating the error IllegalArgumentException: MetaClass not found for
keymanager_KeyUnique:

    <keyValueInstance id="keyValueInstance">
        <loader>
            <query>
                <![CDATA[select count(u.uniqueNumber) from keymanager_KeyUnique u]]>
            </query>
        </loader>

        <properties>
            <property name="numberOfKeys" datatype="decimal"/>
        </properties>

    </keyValueInstance>

</data>

I have had no luck in finding a solution to this.

Hi,
Please double check if there is an entity ‘KeyUnique’ in your project.

BR,

I loaded it to Github dalemccut/keymanager001 (github.com).

Yes there is a entity: keymanager001/modules/global/src/com/company/keymanager/entity/KeyUnique.java

The query (

) generating the error is in :keymanager001/key-edit.xml at master · dalemccut/keymanager001 (github.com).

The error generated is :

java.lang.IllegalArgumentException: MetaClass not found for keymanager_KeyUnique
