Lock wait timeout exceeded; try restarting transaction

[AA CC, geändert vor 12 Jahren.]

Hi,

i create a create account hook.
Into method onAfertCreate, i inserte this code above

                ArgUser argouser;
		User user = ((User)model);
	        argouser = ArgUserLocalServiceUtil.createArgUser((int)CounterLocalServiceUtil.increment(ArgUser.class.getName()));
	        argouser.setLruserId(user.getUserId());
	        ArgUserLocalServiceUtil.addArgUser(argouser);

The instruction ArgUserLocalServiceUtil.addArgUser(argouser); throw Lock wait timeout exceeded; try restarting transaction .
Why ?
in onAfertCreate the transaction for insert liferay user is still open ?

I'm using MySql

What i had to do ?
Is very urgent please help me.

You should use a ServiceWrapper instead of ModelListener. When the model listener is invoked the transaction is still open. The transaction is committed after the addUser() service call returns (without throwing an exception).

The i had to create a service with a new servicebuilter that remaps UserTable?

Just create a hook plugin that defines a service hook in liferay-hook.xml and extends UserLocalServiceWrapper class and overrides addUser() method.
