I'm fairly new to JHipster, have the following immediate questions:
How to switch to another UI, like for example PrimeNG? Where in the code and what do I have to change to switch from the default UI (which one is it by the way?) to PrimeNG?
How to remove created entities (with all of the created artifacts bound to it and code parts)? For example I just wanted to change the name of an already created entity, but couldn't find how, so I believed the most easiest way would be to delete the old one completely and recreate it again (with new name, etc.).
Cheers

I used some of the Hybris reserved Deployment code and then later changed to non-reserved deployment type codes. Do I need to Initialize the system in-order to reflect the changes with new deployment code or just an Update works. There are many items that deployment code has been changed. Why update doesn't work?
When you use a reserved code in your deployment table, you're likely to add the attributes of your object in an existing table. If you have attributes with the same name, it'll surely be a mess in the table (I don't know how hybris will choose the table type for example).
When you run an update with the good deployment code, it will create a new table which is just fine. The other table which has been used by two objects will still remain potentially broken because hybris won't delete any column.
That's why you should initialize your system to have a clean DB. The issue is that you'll lose all your data.
If you need to migrate data it will be probably quite hard because you must have to look on the broken table and distinguish between the attributes that should not be there and the others. So I hope for you that it's just a dev issue!
Actually i would suggest you to do initialize rather than update more likely that the update will not work for you in this case and probably you will get some error messages saying invalid pk xxxxxxxxxxxx because of unknown typecode yyyy.
As you may know the typeCode (deployment code) is an essential operator for the generation process of PKs in Hybris and thanks to it Hybris can ensure the uniquenessity of the PKs, so even if you change the old typeCode with a new one it's very likely that Hybris will still keep the old typeCode somewhere hence PKs already generated will never be consistent with the new typeCode.
So that's why you should never change the typecode of an item once given.
My suggestion is :
To make a backup of your existing data (you can export it from HMC,
you may take a look at alain.janinm's answer here).
Then initialize your System.
Then re-import the data again.
Note : that typecodes between 0 and 10000 are already reserved for hybris
particular items.
I tried using smart image in multi composite field. In that the images are getting persisted, the remaining fields in the multi composite fields are not getting persisted. when i edited the dialog for the first time the values are getting stored on the node. when i edit the dialog next time it is showing me empty fields for the fields other than smart image.
This won't work. SmartImage and SmartFile have some restrictions to them. And there are two different versions: SmartImage and SmartFile vs. Html5SmartImage and Html5SmartFile. Depending on your actual Version of CQ it is even only possible to have the smartimage as a separate tab without any other fields. On top of that the behaviour for the different browser and versions together with the configuration of your SmartImage have different outcomes in JCR. This is even true for AEM 5.6.1 and the Html5 versions of the the xtype.
I can't post the full solution (as the code is not mine) but give some pointers how you could achieve your requirement:
Write your own Widget that replaces the multifield xtype. The author called it genericmultifield and what it does is to open an additional configurable dialog for each item. In this dialog you have the full controll again. It stores each item as a separate node below your resource from where you open your main dialog.
Though you need good ExtJs knowledge to achieve this and considering AEM 6, with a complete new Touch UI I am not sure if it is wise to do so. I didn't have time to check out AEM6, but maybe they already have something like this in their new UI.
I've created my own solution with a custom entity of type activity. I'd like to show a message whenever a new instance of it is created using an existing contact but not allow the user to create one, if only attempting to do that without going via contact.
Basically, my aim is that it won't be impossible to just create that activity (the form will be hidden directly at any attempt except for one way only). The user will have to go to contacts (or leads etc.) and in there add and create an instance of the custom activity entity. That way, I can assure that the field "regarding" will be filled out already.
I'm guessing that I need to detect somehow that the opening of the form is a creation attempt. How can I do that?
Also, as it is now, the user can't create a contact-less activity of the custom type because it doesn't appear on the menu with other activities. I must have disabled it somehow but I have no idea how. Anybody who has one?
You could do this a bunch of ways but the easiest would probably be to:
Make the regarding field read only.
Make the regarding field mandatory.
That way if a user opens a create new form they wont be able to set the regarding and because its mandatory they wont be able to save the record. When they open via an existing contact the regarding field will be mapped automatically. That said in this case just making it mandatory my be enough.
(As a side JavaScript can be used to identify the current form state, but I'm not sure how useful that is here).
In terms of where custom activities appear, by default mine show in a number of locations, for example:
CRM > Workplace > Activities > Ribbon > Other Activities > XXX.
CRM > Workplace > Activities > View Selector > XXX.
They don't show under the left hand navigation of the workplace because they are grouped under 'Activities'. I'm pretty sure these are all the default settings.
You can exercise greater control by editing the sitemap, where you can put pretty much anything, anywhere.
In addition to Mr Wood, I'd like to show you some code. It works as supposed to but I'm not sure if it's optimal.
var foo = function () {
var whatIsGoingOn = Xrm.Page.ui.getFormType();
if (whatIsGoingOn === 1)
alert("Let there be an entity!");
else
alert("Not a creation...");
}
The other states' (deletion, update etc.) numeric values are listed here.
Answering the second part of your question:
When you create a custom activity you can choose whether to have it appear in 'normal' Activity menus or not by checking the box at the top right of the entity form. This is a once-only choice as far as I know and can't be changed later.
For your setup, I would suggest NOT checking this box, so it does not appear in the activity menus to avoid users even being tempted to do it that way.
Instead, add an explicit relationship to the activity N:1 to Contact, and another N:1 to Lead. Use this relationship to add your activity to the left navigation of Contact and Lead forms, or add a grid for them (depends on how you want to use this and if you need to filter the view to something other than the default "Associated View").
When a user navigates to this section they will see if any previous activities of this type exist, and be able to add a new one. BUT this means that the child record is a child via this relationship, not using "regarding", so use a script on the form for the activity so that if Contact is filled in, it is copied to Regarding, and if Lead is filled in then that is copied. If neither, then use an alert or other means to warn the use that something is wrong (see comment earlier). If you want Regarding to be read-only but filled in by script, you will need to make sure to use the force the value to be saved:
Xrm.Page.getAttribute("regardingobjectid").setSubmitMode("always");
You must have the lookups for Contact and Lead on the form to be able to use them in your scripts, but you can make them not "visible by default" so they are there but not seen by the user (and taking up no space).
I have an NSTableView which is populated via a CoreData-backed NSArrayController. Users are able to edit any field they choose within the NSTableView. When they select the rows that they have modified and press a button, the data is sent to a third-party webservice. Provided the webservice accepts the updated values, I want to commit those values to my persistent store. If, however, the webservice returns an error (or simply fails to return), I want the edited fields to revert to their original values.
To complicate matters, I have a number of other editable controls, backed by CoreData, which do not need to resort to this behaviour.
I believe the solution to this problem revolves around the creation of a secondary Managed Object context, which I would use only for values edited within that particular NSTableView. But I'm confused as to how the two MOC would interact with each other.
What's the best solution to this problem?
The easiest solution would be to implement Core Data's undo functionality. That way you make the changes to Core Data but if the server returns the error, you just rollback the changes. See the Core Data docs for details.
I'm wondering what strategies people are using to handle the creation and editing of an entity in a master-detail setup. (Our app is an internet-enabled desktop app.)
Here's how we currently handle this: a form is created in a popup for the entity that needs to be edited, which we give a copy of the object. When the user clicks the "Cancel" button, we close the window and ignore the object completely. When the user clicks the "OK" button, the master view is notified and receives the edited entity. It then copies the properties of the modified entity into the original entity using originalEntity.copyFrom(modifiedEntity). In case we want to create a new entity, we pass an empty entity to the popup which the user can then edit as if it was an existing entity. The master view needs to decide whether to "insert" or "update" the entities it receives into the collection it manages.
I have some questions and observations on the above workflow:
who should handle the creation of the copy of the entity? (master or detail)
we use copyFrom() to prevent having to replace entities in a collection which could cause references to break. Is there a better way to do this? (implementing copyFrom() can be tricky)
new entities receive an id of -1 (which the server tier/hibernate uses to differentiate between an insert or an update). This could potentially cause problems when looking up (cached) entities by id before they are saved. Should we use a temporary unique id for each new entity instead?
Can anyone share tips & tricks or experiences? Thanks!
Edit: I know there is no absolute wrong or right answer to this question, so I'm just looking for people to share thoughts and pros/cons on the way they handle master/details situations.
There are a number of ways you could alter this approach. Keep in mind that no solution can really be "wrong" per se. It all depends on the details of your situation. Here's one way to skin the cat.
who should handle the creation of the copy of the entity? (master or detail)
I see the master as an in-memory list representation of a subset of persisted entities. I would allow the master to handle any changes to its list. The list itself could be a custom collection. Use an ItemChanged event to fire a notification to the master that an item has been updated and needs to be persisted. Fire a NewItem event to notify the master of an insert.
we use copyFrom() to prevent having to replace entities in a collection which could cause references to break. Is there a better way to do this? (implementing copyFrom() can be tricky)
Instead of using copyFrom(), I would pass the existing reference to the details popup. If you're using an enumerable collection to store the master list, you can pass the object returned from list[index] to the details window. The reference itself will be altered so there's no need to use any kind of Replace method on the list. When OK is pressed, fire that ItemChanged event. You can even pass the index so it knows which object to update.
new entities receive an id of -1 (which the server tier/hibernate uses to differentiate between an insert or an update). This could potentially cause problems when looking up (cached) entities by id before they are saved. Should we use a temporary unique id for each new entity instead?
Are changes not immediately persisted? Use a Hibernate Session with the Unit of Work pattern to determine what's being inserted and what's being updated. There are more examples of Unit of Work out there. You might have to check out some blog posts by the .NET community if there's not much on the Java end. The concept is the same animal either way.
Hope this helps!
The CSLA library can help with this situation a lot.
However, if you want to self implement :
You have a master object, the master object contains a list of child objects.
The detail form can edit a child object directly. Since everything is reference types, the master object is automatically updated.
The issue is knowing that the master object is dirty, and therefore should be persisted to your database or whatnot.
CSLA handles this with an IsDirty() property. In the master object you would query each child object to see if it is dirty, and if so persist everything (as well as tracking if the master object itself is dirty)
You can also handle this is the INotifyPropertyChanged interface.
As for some of your other questions :
You want to separate your logic. The entity can handle storage of its own properties, and integrity rules for itself, but logic for how different object interact with each other should be separate. Look into patterns such as MVC or MVP.
In this case, creation of a new child object should either be in the master object, or should be in a separate business logic object that creates the child and then adds it to the parent.
For IDs, using GUIDs as the ID can save you quite a bit of problems, because then you don't have to talk to the database to determine a correct ID. You can keep a flag on the object for if it is new or not (and therefore should be inserted or updated).
Again, CSLA handles all of this for you, but does have quite a bit of overhead.
regarding undo on cancel : CSLA has n-level undo implemented, but if you are trying to do it by hand, I would either use your CopyFrom function, or refresh the object's data from the persistance layer on cancel (re-fetch).
i just implemented such a model.but not using NH, i am using my own code to persist objects in Oracle Db.
i have used the master detail concept in the same web form.
like i have master entity grid and on detail action command i open a penal just below the clicked master record row.
On Detail Add mode, i just populate an empty entity whose id were generated in negative numbers by a static field.and on Save Detail button i saved that entity in the details list of the Master Record in Asp.NET Session.
On Detail Edit,View i populated the Detail Panel with selected Detail through ajax calls using Jquery and appended that penal just below the clicked row.
On Save Button i persisted the Master Session (containing list of Details) in database.
and i worked good for me as if multiple details a master need to fill.
also if you like you can use Jquery Modal to Popup that Panel instead of appending below the row.
Hope it helps :)
Thanks,
