Does anyone have an example of how to add a field to a Mapped cache extension? I am trying to extend the SalesPrice functionality in 2019R1. It looks a lot like a DAC... but something tells me I cant simply just make an extension for it..
Thanks
Please see below the diagram showing how it works.
In short, you create a generic graph and a class inherited from PXMapppedCacheExtension which will have all the fields that you need for your reusable logic.
Then you declare the mapping to the class and the implementation of the generic graph.
Please find the complete description by the following link.

I am now familiar with "basic" Typo3 - Usage and templating. Right now, I am stuck though, because I am not familiar with custom extensions etc.
I am looking for a way to represent Objects, that I get via methods of my own php-class from an XML-DB-Interface, in Typo3.
To be more precise :
I have a really complex XML-Interface and a php-class which is complete already, to interact with that interface, making methods available, that are meant to interact with different object-types in the underlying DB.
I now want to create abstract objects with the corresponding attributes in Typo3 to be able to work with them in typo3 (display/create/modify).
Furthermore, it would be helpful to find a way to "link" the functions of my php class to typo3-functions, so I can (perhaps?!) build up some kind of simple report-generator that generates conditional reports of those objects.
Could anybody lead me into the right direction and link (a) HowTo(s) or perhaps even examples that I could modify?
Thanks in advance, Oliver
Check how DBAL extension is coded.

You might want to implement this XML system as your own abstraction system to store your objects and use TYPO3 backend forms to manipulate those.
According to the code sample on MSDN (http://msdn.microsoft.com/en-us/library/hh552522.aspx) any custom property data that you need to get out of your control should be in a semicolon delimited string in the AccessibleObject's Description property. This does not seem right to me at all. This seems like just a quick and dirty trick to get it working. What is the correct way to get the value of properties from custom controls? And if this actually is how you're supposed to do it, then how are you supposed to set those properties using the SetPropertyValue method? The example in the link above just throws a NotImplementedException in SetPropertyValue.
Since the IAccessible interface has only a limited number of properties the best solution is to cram any extra information into the Description property (that's what they do at the company I work at, and our developers don't work quick and dirty :) ). To modify the return value of this property you have to implement the Iaccessible interface on your control. Or, since you only want to modify the Description property you only need to modify that property and leave the rest to the proxy (I'm not sure how this works exactly but there are tutorials for it on MSDN).
The SetPropertyValue method in the UITestPropertyProvider is for the UItestControls. By overwriting it you can modify the way CUIT interacts with the control during playback. For example, if you overwrite SetPropertyValue for the Text property you can change the way CUIT types strings into the control.
I am currently using Asp.Net MVC 4 and I would like to include the time of some routines used by my controllers in the glimpse's timeline tab.
I know that I have to create an ITimeLineMessage Implementation and send the timing information with a message broker. But how to create the ITimeLineMessage ?
Here is an implementation using anthonyv's suggestion:
https://gist.github.com/droyad/8292852
Here is a way but its not very nice and not supported:
Retrieve the MessageBroker for the following static method:
Glimpse.Core.Framework.GlimpseConfiguration.GetConfiguredMessageBroker()
Then publish an ITimelineMessage to the MessageBroker:
messageBroker.Publish(timelineMessage)
Note, you could create a generic message type that you use over again that implements ITimelineMessage
To populate the properties of your ITimelineMessage implementation you might also need IExecutionTimer. You can get this via the following static method:
Glimpse.Core.Framework.GlimpseConfiguration.GetConfiguredTimerStrategy()
The above will have the knowledge of when the request started for offsets etc.
As #nikmd23 said, we know this is about as bad as what you could ever want to do but v2 will see a much much more simple way of doing this.
You can create any custom class you want, that class just has to implement ITimelineMessage.
As a general heads up, we are currently working through a way to make this WAY easier. If the approach described there interests you, please do provide your feedback.
I want to add 3 more methods and one field to liferay.portal.model.User class. Anyone knows how can I do this? Can I switch the class by hook like this:
<service>
<service-type>com.liferay.portal.model.User</service-type>
<service-impl>my.pack.userExpanded</service-impl>
</service>
I want to have a close look at service builder but can't find good sources which will show how to switch liferay class with my own class (cause of too many uses).
So second question is does anyone know about some good tutorial or blogs regarding this? Especially I am interested in adding extra methods and fields.
The standard Liferay Developer Documentation is good:
http://www.liferay.com/documentation/liferay-portal/6.1/development/-/ai/overriding-a-portal-servi-4
Another alternative is to add Custom Fields to User entity:
You can't modify a liferay entity. Neither you can use hook to modify these things, hook can only modify limited things as suggested by the documentation.
I don't think you can even use a EXT to modify a liferay entity.
So now the what comes to my mind remains is to create custom-fields for your field requirement and build a helper utility class which will provide you with your required User methods.
You can make the helper class available to the portal by packaging in a jar and pasting it in the global path (in tomcat [TOMCAT_HOME]/lib/ext).
Can somebody give me a use case as to how can the PortletURLListener be used? if it can be used at all?
Like we have ModelListener can we also use PortletURLListener?
Just like in ModelListener we can inject functionality on creation of a model, on update of a model or on delete and so on.
So can we use the PortletURLListener the same way like ModelListener to do
something when a specific URL is called? Any other approach if not PortletURLListener? Since the name is such I thought that could be of help.
And can we use it in a hook? or it is just used by Liferay? Any other practical usecase you have seen or implemented by extending or using this class?
Thanks in advance.
Thanks Mark for the prompt :-)
The PortletURLListener is used e.g. for deploying and undeploying by Liferay core. For more details see Liferay sources for PortletHotDeployListener:
https://github.com/liferay/liferay-portal/blob/master/portal-impl/src/com/liferay/portal/deploy/hot/PortletHotDeployListener.java
Answer after Update:
You can create hook and put servlet.service.events.post=com.my.MyAfterChangeAction propery to the portal.properties. The MyAfterChangeAction class must implements com.liferay.portal.kernel.events.Action.
