QUESTION

UI5 extension of controller and lifecycle methods

Asked 2021-Jun-14 at 17:19

I'm trying to create a base controller that has common methods and common onInit logic.

Using the extend method adds the methods from the base controller to the child controller, but the lifecycle methods get overwritten completely.

I tried using the override.onInit approach shown on this documentation page but it did not work.
I also tried with sap.ui.component like this but I couldn't get it to work at all.
I'm not sure if it should work with the AMD syntax.

As far as I understood, the extension feature should replace common methods that have been overridden, but it should execute the lifecycle methods from both the base and extension controller on this respective order.

So my question are the following:

Is this behavior possible to achieve? If so, what am I doing wrong?
Is there a better way to implement it?

Example code:

Parent controller

I didn't know there is an override mechanise in UI5 and it looks over-engineered... My guess is you are on an older version without proper support.

Anyhow, js-inheritance works out of the box. You need to call "super".

The result of the ___str___ method may differ because of the encoding used.

To replace \n with a new line, call the .replace(oldvalue, newvalue) method on the string object. In your case you need to replace \\n with \n (replace the escaped string "\n" with the newline character)

Something like

Cloud formation failed to create Security group with VPCIdNotSpecified

Asked 2021-Jun-08 at 20:28

Problem :

While creating Security group using cloud formation template, it fails with VPCIdNotSpecified error even though I have provided VPCID as an input.

Background : I have deleted the default VPC that comes with the account and created my own VPC. Also, I am getting the VPC ID as a parameter input. \1/used aws cli to verify the template and its good. All the input parameters were fetch correctly and shown in summary page of cloud formation creation. It even shows the VPCID which is matched.

The scope of a SG is limited within a VPC. So its a mandatory field while creating a SecurityGroup to specify a value for VpcId .

It may be an item under EC2 buts its scope is within a VPC. You cannot create a SG without specifying a VPC. Just like you cant create an EC2 without specifying its Subnet and VPC.

Can you remove ** and try?

ANSWER

Answered 2021-May-30 at 05:21

It seems that the way the two individual queries are combined is wrong.

The UNIONed subqueries do not project the AcctName column required for grouping the results.

The textual description of what the queries are supposed to do in the original question misleadingly states that the data ranges used in the two queries overlap. Looking at the actual SQL code examples for the queries, it is clear, that Q2 is intended to cover all data valid for time before the data range in Q1.

One way to combine the query is the UNION that was tried by the OP. For that to work, the queries need to expose the same columns, especially those required for the GROUP BY operation:

First download the Python: sap_xssec lib. It should allow you to get at attributes for JWT token.

You could use Process Monitor while running the relevant part of the program to see, which file is missing and the path it should be in. Exclude all other events than file events and filter out all SUCCESS messages.

Perhaps it is referenced relative to the calling DLL (where Sap.Data.Hana.HanaUnmanagedDll.SearchNativeDlls is defined).
