[Fiori Elements] Custom Column in a Table is not visible
I had a generated Fiori Elements App (done by using @sap/generator-fiori), containing a List, where I needed to add a custom column containing a Button. I found this well explained in the official documentation:
https://sapui5.hana.ondemand.com/#/topic/d525522c1bf54672ae4e02d66b38e60c
I followed the instructions exactly, but it didn’t work. When comparing my manifest.json again with the example, I noticed one minor difference. In my generated App, there was an extra items/ in front of the @com.sap.vocabularies.UI.v1.LineItem.
After removing items/ the custom column was suddenly visible. When I noticed the difference, I thought that would never be the reason. Luckily, I tested it after all. That really is a big problem with Fiori Elements. These are problems that can no longer be solved by debugging or similar.
Here some more helpful links, when challenging with a custom column:
[CAP] Fiori Elements – Add button in table toolbar to trigger action
A button for calling an action or function can be added to a table header with a single line in the annotations.cds file:
UI.LineItem : [
{ $Type: 'UI.DataFieldForAction', Action: 'myService.EntityContainer/myAction', Label: 'This is my button label' },
...
],
[CAP] Fiori Elements – Add section with PDFViewer
I have a CAP Service that provides a PDF file that I needed to display in a Fiori Elements frontend using the sap.m.PDFViewer. The viewer should be placed in a section on the object page after navigating from the ListReport main page.
My CAP Service has the following annotations to provide the PDF.
entity pdfFiles : cuid, managed {
content : LargeBinary @stream @Core.MediaType: mediaType @Core.ContentDisposition.Filename: fileName @Core.ContentDisposition.Type: 'inline';
mediaType : String @Core.IsMediaType: true;
fileName : String @mandatory;
}
Add a custom section to your view following this example: https://sapui5.hana.ondemand.com/test-resources/sap/fe/core/fpmExplorer/index.html#/customElements/customSectionContent
Two steps are necessary.
1. Add a new section via the manifest. The template path should match your app namespace.
"ObjectPage": {
"type": "Component",
"id": "ObjectPage",
"name": "sap.fe.templates.ObjectPage",
"viewLevel": 1,
"options": {
"settings": {
"editableHeaderContent": false,
"entitySet": "pdfFiles",
"content": {
"body": {
"sections" : {
"myCustomSection": {
"template": "sap.fe.core.fpmExplorer.customSectionContent.CustomSection",
"title": "{i18n>pdfSection}",
"position": {
"placement": "After",
"anchor": "StandardSection"
}
}
}
}
}
}
}
}
2. Add the section content by defining a new fragment in the file CustomSection.fragment.xml
<core:FragmentDefinition xmlns:core="sap.ui.core" xmlns="sap.m" xmlns:l="sap.ui.layout" xmlns:macro="sap.fe.macros">
<ScrollContainer
height="100%"
width="100%"
horizontal="true"
vertical="true">
<FlexBox direction="Column" renderType="Div" class="sapUiSmallMargin">
<PDFViewer source="{content}" title="{fileName}" height="1200px">
<layoutData>
<FlexItemData growFactor="1" />
</layoutData>
</PDFViewer>
</FlexBox>
</ScrollContainer>
</core:FragmentDefinition>
On the ObjectPage you will now have a new section containing the PDFViewer.

[CAP] Using a Tree in SAPUI5 Freestyle app
The following Links helped me implementing the tree functionality:
https://sapui5.hana.ondemand.com/#/entity/sap.m.Tree/sample/sap.m.sample.TreeOData
https://answers.sap.com/questions/13192367/sap-cds-how-to-add-hierarchy-annotations-saphierar.html
Define the data model in data-model.cds
entity Node {
key NodeID : Integer;
HierarchyLevel : Integer;
ParentNodeID : Integer;
Description : String;
drillState : String;
}
Create testdata in my.test-Node.csv
NodeID;HierarchyLevel;ParentNodeID;drillState;Description
1;0;null;"expanded";"1"
2;0;null;"expanded";"2"
3;0;null;"expanded";"3"
4;1;1;"leaf";"1.1"
5;1;1;"expanded";"1.2"
6;2;5;"leaf";"1.2.1"
7;2;5;"leaf";"1.2.2"
and deploy the testdata to your local sql db
cds deploy --to sqlite:db/test.db
Service Definition in test-service.cds
using my.test as db from '../db/data-model';
service testService {
entity Nodes as projection on db.Node;
}
add the Tree controll to your Fiori UI view Tree.view.xml
<Tree
id="Tree"
items="{path: '/Nodes',
parameters : {
countMode: 'Inline',
numberOfExpandedLevels: 3,
treeAnnotationProperties: {
hierarchyLevelFor : 'HierarchyLevel',
hierarchyNodeFor : 'NodeID',
hierarchyParentNodeFor : 'ParentNodeID',
hierarchyDrillStateFor : 'drillState'
}
}
}">
<StandardTreeItem title="{Description}"/>
</Tree>
The output should be similar to this:
[SAPUI5] Binding with filter on XML View
https://sapui5.hana.ondemand.com/sdk/#/topic/5338bd1f9afb45fb8b2af957c3530e8f.html
There are two ways to use a filter.
Option 1:
items="{
path: '/myItems',
parameters : {
$filter : 'itemName eq \'myItemName\'',
$orderby : 'createdAt desc'
},
}">
Option 2:
items="{
path: '/myItems',
parameters : {
$orderby : 'createdAt desc'
},
filters : {
path : 'itemName ',
operator : 'EQ',
value1 : 'myItemName'
},
}">
[OpenUI5] SAP Fiori elements add-on for OpenUI5 using an OData V4 service
Recently I found this blog post about the new SAP Fiori elements add-on for OpenUI5.
https://blogs.sap.com/2020/12/21/now-available-sap-fiori-elements-add-on-for-openui5/
It includes a little exercise to try it out for yourself. I wrote down all steps I had to make on my Linux Mint 20 installation.
These two links also helped me a lot.
https://github.com/sap-samples/cloud-cap-samples
https://cap.cloud.sap/docs/get-started/
Prerequisites (Node.js, Visual Studio Code, SAP Fiori tools, Git)
curl -sL https://deb.nodesource.com/setup_15.x | sudo -E bash -
sudo apt-get install -y nodejs
node --version
npm -v
Change npm’s default directory to prevent permission errors.
https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
mkdir ~/.npm-global/lib
#add the following line to your .bashrc or .profile or .zshrc
export PATH=~/.npm-global/bin:$PATH
Step 1: Provide an OData V4 service
git clone https://github.com/sap-samples/cloud-cap-samples remote-odata-service
cd remote-odata-service
npm i
npm i -g @sap/cds-dk
cds watch fiori
Step 2: Generate a SAP Fiori elements List Report Object Page (LROP) app with Fiori tools
1. Open VSC, press Ctrl + P and search for > Fiori: Open Application Generator
2. Choose SAP Fiori elements application
In my case there was no default generator, so first I had to install it.
npm install -g @sap/generator-fiori-elements@latest
This can also be done directly in VSC.
3. Select List Report Object Page
4. Select Connect to an OData Service as Data source and enter as URL http://localhost:4004/browse
5. Choose Books as the Main entity and texts as Navigation entity
6. Complete the mandatory information module name (e.g. bookshop) and Project folder path for storing your app. Of course, you can also fill in the optional information.
Step 3: Make changes in package.json and ui5.yaml required for using OpenUI5
package.json
{
"name": "fiorielements_openui5",
"version": "0.0.1",
"private": true,
"sapux": true,
"description": "A Fiori application.",
"keywords": [
"ui5",
"openui5",
"sapui5"
],
"main": "webapp/index.html",
"scripts": {
"start": "fiori run --open index.html",
"start-local": "fiori run --config ./ui5-local.yaml --open index.html",
"build": "ui5 build -a --clean-dest --include-task=generateManifestBundle generateCachebusterInfo",
"deploy": "fiori add deploy-config"
},
"devDependencies": {
"@sap/ux-specification": "latest",
"@sap/ux-ui5-tooling": "1",
"@ui5/cli": "2.5.0",
"@ui5/fs": "2.0.1",
"@ui5/logger": "2.0.0"
},
"ui5": {
"dependencies": [
"@sap/ux-ui5-tooling",
"@sap/open.fe"
]
},
"dependencies": {
"@sap/open.fe": "1.85.0"
}
}
ui5.yaml
specVersion: '2.2'
metadata:
name: 'fiorielements_openui5'
type: application
framework:
name: OpenUI5
version: "1.85.0"
libraries:
- name: sap.m
- name: sap.ui.core
- name: sap.uxap
- name: themelib_sap_fiori_3
server:
customMiddleware:
- name: fiori-tools-proxy
afterMiddleware: compression
configuration:
ignoreCertError: false # If set to true, certificate errors will be ignored. E.g. self-signed certificates will be accepted
backend:
- path: /browse
url: http://localhost:4004
- name: fiori-tools-appreload
afterMiddleware: compression
configuration:
port: 35729
path: webapp
Step 4: Run the V4 application
cd ~/projects/fiorielements_openui5
npm i
npm start
Now http://localhost:8080/index.html should be opened in your browser.
“Note: Clicking on the Go button in List Report application might request user and password. Please enter user alice, no password.”
Finally I got my list items.
[Fiori] Debug deployed Fiori App
When opening the Dev-Tools for a deployed Fiori App, it will look like this:
You won’t see any controller.js to debug.
What to do? Close the Debugger-Tools and hit CTRL+ALT+SHIFT+P to open the Technical Information Dialog
Check the Checkbox (or choose a specific controller) and reload the app.
It reloads with a new URL parameter and if you open the Dev-Tools, you will now see the controller.js.
Other options to debug or at least to collect some information about your app are the UI5 Diagnostics (hit CTRL+ALT+SHIFT+S) and the UI5 Inspector which is a Brower Addon.
