Introduction I posted two blog posts this week, and each of them had a particular drawback - lack of cluster coordination. The first blog post on cluster-enabled upgrade processes introduced using an @Reference dependency upon a specific Release version, the idea being that the component shouldn't start unless that version was available. When the upgrade process would run on the cluster...

I recently was helping a client with an upgrade process and that had run into a little problem... A few of the model hints were not updated on some of the columns in their Service Builder services and, as we all know, Service Builder will not ensure the columns are changed in a production environment (well, actually any environment where the schema.module.build.auto.upgrade property is not set...

A really quick post to share something important with you React + Clay developers out there... A recent update to Clay had a breaking internal change. If after deploying your React portlet and you try to place it on the page and you get errors in the JS console like: liferay-amd-loader | Errors returned from server for require( ["my-module@1.0.0"] ): "Missing dependency...

Introduction A client asked me to build a React portlet for them and I was like, "Oh Yeah!" I mean, it's been a while since I built a React portlet and tooling has really changed a lot since then, so I was really looking forward to this new task. So without further ado, I'm just going to dive right in... Creating the Module Okay, so this is still Liferay and still OSGi, so we're going to be...

IntroductionAs many folks know, I'm known for telling people not to look inside the Liferay database itself. It's not always clear what is what in the DB and Liferay has a lot of code around retrieving and updating data that you likely will not get completely right if you were to update the DB directly.I typically end with "Always, always use the Liferay API for your data needs..."And, if...

So some time ago I wrote the Cluster Details marketplace plugin. Basically you drop this guy into all of your Liferay clusters and you get a nifty little control panel that tells you details about the cluster, all of the nodes which have joined the cluster and it identifies who the leader of the cluster is at the moment:Not super complicated, but it is a handy little tool to identify details...

IntroductionHistorically developers have always wanted to be able to control site creation.It's not that Liferay admins are untrusted or anything like that. It is really more the case where setting up a new site can get complicated and the steps to create the site could be quite long. A site may have initial documents, web contents (with structures and templates), pages to create and populate...

IntroductionLiferay has, for a long time, supported RBAC, the role-based access control. It is, of course, backed by the database so (inheritance aside for the moment) a user will be assigned a list of roles that is mostly fixed or unchanging. To change these role assignments, typically an admin is going to log into Liferay and, using the control panel, add or remove roles as necessary.This...
