org.apache.hivemind.ApplicationRuntimeException -- duplicate method: getXType

[Cliff Zhao <zh...@gmail.com>]

In my page specification, I have:
1. a property xType
2. a PropertySelection component which use the Simple String model
3. binding the value parameter of PropertySelection to the property xType
Also, I have this method in my page class:
public abstract String getXType();

Then I got this exception:
org.apache.hivemind.ApplicationRuntimeException
Error at context:/WEB-INF/QueryTransaction.page, line 5, column 21: Error
adding property XType to class lnp.gui.page.QueryTransaction: Unable to add
