Can`t Store Liferay Service Entity ´with composite primary key

[Daniel Breitner, módosítva 12 év-val korábban]

Hi you all !

Quick question:

I defined a Service Entity like this:

<entity name="Test" local-service="true" remote-service="false">
		<column name="part1" type="long" primary="true" />
		<column name="part2" type="long" primary="true" />
		<column name="part3" type="long" />
	</entity>

"part1" and "part2" are forming a Primary key.

A class called TestPK has already been created for me.

To store a new "Test" object, I need first to create a new TestPK and use it to store the Test object.

TestPK testpk= new TestPK(someValue, anotherValue);
TestLocalServiceUtil.createTest(testpk)

But whenever I do this I get the following exception:

21:26:12,708 ERROR [ClassLoaderProxy:70] java.lang.IllegalArgumentException: argument type mismatch
java.lang.IllegalArgumentException: argument type mismatch

Hi Daniel!
Since ClassLoaderProxy used, I suppose you defined services in one portlet - and trying to use them from another portlet.
Is it your situation?

Hi Daniel, What Liferay version are you using?

Hi Daniel!

I've used the same and its working fine.

I am using LR 6.1EE and defined services in one portlet and accessing in another portlet.

TestPK testpk= new TestPK(someValue, anotherValue);
TestLocalServiceUtil.createTest(testpk)

This is a class loader issue. You cannot create the instance in the portlet consuming the service and pass it to the portlet providing the service.

In the portlet providing the service, edit the TestServiceImpl class and make a "Test createTest(long someValue, long anotherValue);" method that invokes the create process and returns the instance. Portlet consuming the service would use this method.
