invokeAction - error handling and results

[wozjac]

Hello,

Scenario 1

1. CAP V4 service with an action with 3 parameters. The implementation checks the parameters, if invalid it throws an error.
2. This action is added to the List page, in the table toolbar

   "targets": {
       "MyListPage": {
         "type": "Component",
         "id": "MyListPage",
         "name": "sap.fe.templates.ListReport",
         "options": {
           "settings": {
             "entitySet": "MyEntitySet",
             "variantManagement": "Page",
             "hideFilterBar": true,
             "navigation": {
               ...
             },
             "controlConfiguration": {
               "@com.sap.vocabularies.UI.v1.LineItem": {
                 "actions": {
                   "CustomAction": {
                     "press": "my.custom.action",
                     "text": "Some Text",
                     "enabled": true,
                     "visible": true
                   }
                 }
               }

3. The controller extends ControllerExtension, invokes action passing only the model (unbound action).

...
let parameters = {
   model: this.base.editFlow.getView().getModel(),
    label: "Confirm",
};
this.base.editFlow.invokeAction(actionName, parameters)

4. If the backend responds with an error, no error dialog shown in the ui, dumps on operations.js.

Scenario 2

1. The same action responds with req.reply passing a result object.
2. invokeAction.then((res) => { }) function does not receive it (res is undefined)?

Hi @wozjac,

thanks for using the feature showcase.

Both issues should be fixed with UI5 Version 1.110.0 coming most likely next week / the week after.

Please excuse any issues. Scenario two was a limitation for unbound actions, for bound actions it should already work.

If you have to use a previous UI5 version you can fallback to the UI5 default: https://sapui5.hana.ondemand.com/#/topic/b54f7895b7594c61a83fa7257fa9d13f and the result will be available through the bound context of the operation.

Example:

const oOperation = this.base.getModel().bindContext('/unboundAction(...)')

        oOperation
          .setParameter('param1', 'value 1')
          .setParameter('param2', 'value 2')
          .setParameter('param3', 'value 3')
          .execute()
          .then(
            function () {
              //some logic
            }.bind(this),
            function (oError) {
              MessageBox.error(oError.message)
            }
          )

Hope that helps & BR, Marten

Hi @schiwekM,

is that also an issue in 1.108 LTS release? Will it be patched also there?
