BUG: WebCenter Spaces MDS vs Custom Task Flow

El otro día encontré un error muy curioso durante el despliegue y configuración de un Custom Task Flow en una plataforma WebCenter Portal : Spaces 11.1.1.6.

Enlace versión inglés
Link to english version

Durante la configuración de los parámetros del Custom Task Flow y al hacer click en Save de Oracle Composer NO persistía los cambios en el MDS. Es más, el Task Flow ni se registraba en la página.

En las trazas de WC_Spaces me encontré el siguiente error:

java.lang.IllegalArgumentException: Invalid UUID string: df
    at java.util.UUID.fromString(UUID.java:204)
    at oracle.mds.internal.persistence.MDSGUIDImpl.<init>(MDSGUIDImpl.java:51)

Probando en una Custom Portal Application verifiqué que todo funcionaba de manera correcta.
Haciendo mas pruebas encontré que si el Task Flow se encontraba en una view diferente a la principal los parámetros eran registrados correctamente en el MDS.

El problema se acotaba a la view principal del Task Flow. Por alguna razón, en la página principal del Task Flow los cambios en Oracle Composer no eran persistidos.


Habilitando las trazas a nivel DEBUG del MDSSandBox de WebCenter Spaces se observa que la etiqueta que utiliza y genera para cuando se adhiere el Task Flow contenia por medio la ruta de una imagen PNG que estaba en el código de la view.

[2013-04-11T19:21:25.364+01:00] [WC_Spaces] [TRACE:32] [] [oracle.mds.sandbox] [tid: [ACTIVE].ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: wbdevadmin] [ecid: 62340e71fac4a771:-495fe158:13dfa480d34:-8000-0000000000000e2d,0] [APP: webcenter#11.1.1.4.0] SandboxHelper.listSandboxes(); Namespace:/oracle/webcenter/doclib/view/jsf CUSTOMIZATIONS; SandboxNamePattern:WCFOWPSSLadfSLimagesSLpmp-mid.pngWCSEPwbdevadminWCRAN%; List of sandboxes:

Justamente esta imágen se corresponde con un background:url que hay en un inlineStyle del código. 

<af:panelGroupLayout id="pgl1" layout="vertical"
                         inlineStyle="background:url('../adf/images/pmp-mid.png') repeat-y white;">

Al eliminar el inlineStyle y sustituirlo por un styleClass el error desapareció y el Task Flow se registraba en MDS correctamente.

OJET: Inter-Module communication in TypeScript Template

Image
In this post I bring another example on how to Communicate Modules using the Oracle JET - TypeScript Template based on the Oracle JET Cookbook: InterModule Communication From now and so on will create multiple examples using TypeScript for those who are not familiar with it and wants to turn the Cookbook examples into TypeScript :). The example ( ojet-typescript-list-detail ) can be found as usual in my GitHub repository: https://github.com/DanielMerchan/ojet-examples This example is a bit different compared to the Cookbook example where the modules are not running at the same time within a Module. This example is built as described in the following images: Customers module acts as the Wrapper Module. It coordinates when to load the list and detail modules. Customers module makes use also of signals npm module for communication between Customers-List, Customers-Detail. Explanation of the Example customers.js is the coordinator responsible module for: initiali

OJET: Build and Deploy in an Application Server

Image
There are some other sources where an Oracle JET Application is packaged and deployed as a WAR in Oracle WebLogic Application Server (Arda Eralp) https://blogs.oracle.com/ardaeralp/deploy-oracle-jet-application-to-weblogic-server (Andrejus Baranovski's) http://andrejusb.blogspot.com/2016/07/serving-oracle-jet-application-from.html They may look bit old or maybe because they call directly grunt tasks by using the grunt-cli . In this post I will update a bit these posts in Oracle JET 6.1.0 and the usage of ojet build (instead of calling the grunt tasks) for also building the corresponding WAR file. The example can be found in my GIT repository: https://github.com/DanielMerchan/ojet-examples Let's start... Install grunt-war module in your Oracle JET Application. npm install grunt-war --save-dev Create a war.js (or call it whatever you want) in /scripts/grunt/config folder under your souce files. This is a sample code inside of it, check https://www.npmjs.com/packag

OJET: Select All options using only Checkboxset

Image
This is an example on how to select all other options by using another oj-checkboxset. GitHub: ojet-checkbockset-select-all The idea is to keep track of the selection and make use of the on-value-changed as described in the following code. self.colorOptions = ko.observableArray([ { id: "blueopt", value: "blue", color: "Blue" }, { id: "greenopt", value: "green", color: "Green" }, { id: "redopt", value: "red", color: "Red" }, { id: "limeopt", value: "lime", color: "Lime" }, { id: "aquaopt", value: "aqua", color: "Aqua" }, ]); self.selectAll = ko.observableArray([]); self.currentColor = ko.observableArray(["red"]); self.selectAllOptionChanged = (event) => { const newSelection = event.detail.value; if (newSelection.indexOf('all')
