Retrieve "property getter" from the property name


Retrieve "property getter" from the property name

This might help you I've been using this method to retrieve a property getter based on the name of the property. , You can construct the delegate type using Reflection:
code :
var delegateType = typeof(Func<>).MakeGenericType(propInfo.PropertyType);
var deleg = propInfo.GetMethod.CreateDelegate(delegateType, instance);

Calling "Base-Getter" in Overriding Getter of Property

Calling "Base-Getter" in Overriding Getter of Property

With these it helps It is (arguably) a bug in the debugger. You can add your vote to this feedback article. This isn't easy to fix, I'm sure, the debugger doesn't have ready access to the base property getter method address since the v-table slot for the property getter has been replaced in the derived class.
One possible workaround is to store the base value in a local variable first so you can inspect that one. That isn't going to make your getter any slower.

To fix this issue Femanager 2.6.0 uses In2code\Femanager\Domain\Model\User (In2code instead of In2) as namespace.
Corrected Typoscript:
code :
config.tx_extbase{
    persistence{
        classes{
            In2code\Femanager\Domain\Model\User {
                subclasses {
                    0 = FederhenSchneider\Extendfemanager\Domain\Model\User
                }
            }
            FederhenSchneider\Extendfemanager\Domain\Model\User {
                mapping {
                    tableName = fe_users
                    recordType = 0
                }
            }
        }
    }
    objects {
        In2code\Femanager\Controller\NewController.className = FederhenSchneider\Extendfemanager\Controller\NewController
        In2code\Femanager\Controller\EditController.className = FederhenSchneider\Extendfemanager\Controller\EditController

        In2code\Femanager\Domain\Validator\ServersideValidator.className = FederhenSchneider\Extendfemanager\Domain\Validator\CustomServersideValidator
        In2code\Femanager\Domain\Validator\ClientsideValidator.className = FederhenSchneider\Extendfemanager\Domain\Validator\CustomClientsideValidator
    }
}

plugin.tx_femanager {
    view {
        partialRootPaths {
            10 = EXT:extendfemanager/Resources/Private/Partials/
        }
    }
}

seems to work fine Issue
You are trying to set the value property of string object which is wrong. string doesn't have any property called value.
code :
#searchCenter='ngModel'
#searchCenter
modifyValue(searchCenter, centerId){
    this.term = centerId._id;
  }
vue: add custom property to "this" inside component, and prevent being added "__ob__" and getter/set

like below fixes the issue When Vue creates a component instance it walks through each property in your data and creates a getter/setter pair for it in addition to attaching an observer if the property is an object/array. This is in order to make the component reactive to state mutations. It results in a small increase in initialization cost and book-keeping cost, but this is quite negligible for all intents and purposes, so I wouldn't worry too much about that.
There's a great talk titled Demystifying Frontend Framework Performance by Evan You, the creator of Vue, in which he compares different performance aspects of frontend frameworks and describes how Vue's implementation fares in comparison to other frameworks. He outlines the trade-offs he had to make to achieve reactivity and comes to the conclusion that unless you're creating a HUGE app you shouldn't usually worry about a performance hit because of the way Vue works.
code :
created() {
 this.group = {
   children: []
 }
}
const group = {children: []}
Object.freeze(group)

// Then in your data
data() {
  return {
    group,
  }
}
