You have probably noticed that once you have saved an object you are not allowed to change it’s ID. This is basically because each object stored on the database needs an immutable unique identifier that can be used to reference that object from other tables. Maximo prevents updating such identifiers to avoid loosing links between […]
In a previous post I have described how to correctly manage a child table in an application using the Application Designer. However, there are better ways of achieving the same goals so I will analyze all the available options to correctly link records in a parent-child relationship. If you are a creating custom objects and […]
This article is obsolete. Please refer to this one. If you are a creating custom objects and applications in TPAE you may need at some point to create a child table like the Subassemblies in the Assets application. Let’s pretend we have a parent table called TB1 and a child table called TB2. TB1: Parent […]
This entry is part of the Maximo Integration Framework series. Maximo uses the Apache Axis library to call external Web Services. Sometimes could be useful enable the logging for this library instead of sniffing connections and protocols to figure out what is going on.Axis uses Apache commons logging for logging which in turn provides a […]
Today I have discovered a nice script called cleanstartcenters.bat that can be used to force the reload of the Start Center for a specific set of users. The usage of this script is documented in this IBM TechNote.Unfortunately, the script seems have some problems or I’m am too silly to use it 🙂 so I […]
This entry is part of the Maximo Java Development series. This is just an example of a Maximo role defined with a custom Java class. In this example I have defined a role that can be used to send emails (Communication Template) to the workorder’s supervisor or to the owner group if the supervisor is […]
This entry is part of the Maximo Java Development series. Today I want to share with you some Java sample code to reset the value of a field when another field is modified.In the example below I have implemented a little piece of logic to reset the WORKORDER.SUPEVISOR field when the WORKORDER.OWNERGROUP is modified. Here […]
Sometimes standard Conditional Expressions are not enough. Sometimes the logic to implement is too complex to be implemented using an SQL expression. In such cases Maximo allows to implement the condition logic in a custom condition class using Java. To implement a condition class you must extend psdi.common.condition.CustomCondition and override evaluateCondition and toWhereClause methods. Here is a […]
This entry is part of the Maximo Java Development series. In this little article I’m going to show how to display a dialog box with Yes/No or OK/Cancel buttons and how to capture the user’s input to execute some custom logic. For example, you have a Java method attached to a button on the toolbar […]
This entry is part of the Java MBO performance optimization golden rules series. Sometimes you have to perform some complex logic or you have to join several tables to retrieve a piece of data. In other cases there is a piece of code where performance is critical. In such cases it may be hard to […]
