Description

Base.java

class abstract Base<T>{
private T entity;
public void setEntity(T t)

{ this.entity=entity; }

public T getEntity(T t)

{ return this.entity; }

protected abstract Class<T> getEntityClass();
onPrepareFromMyForm(){
if(this.entity == null){
try

{ this.entity=getEntityClass().newInstance(); }

catch(Exception e)

{ throw new RuntimeException(e); }

}
}
.....
}

ProductPage.java

public class ProductPage extends Base<Product>{
protected Class<Product> getEntityClass()

{ return Product.class; }

}

ProductPage.html

<t:form t:id="MyForm">
<t:errors/>
<t:label for="input"/>
<input t:type="textfield" t:id="input" value="entity.name" size="40" t:validate="required,minlength=3"/>
<br/>
<input type="submit" value="Submit"/>
</t:form>

exception:
Could not convert 'entity.name' into a component parameter binding: Class java.lang.Object does not contain a property named 'name' (within property expression 'entity.name').

When I debug the app,I fiind PropertyConduitSourceImpl.readMethodForTerm before onPrepareFromMyForm method.

I think the method should be after onPrepareFromMyForm method.
