Convert a Part into a Saveable Instance [Editor]
This section teaches how to make a Part convert into a Saveable Part [Editor]
1. Earlier in 3x this was done using a boolean flag
2. Now it is achieved using @Inject Mdirtable
3. Select the view that is going to act as Saveable Part
4. In that view at class level declare @Inject Mdirtable dirty as shown below
5. Then in 3x save on the editor was performed by a doSave method. This method is made
available in e4 using @Persist annotation. There should be only 1 @Persist annotation in each
Part. The code is as shown below.
Write you save logic in this method and then set the dirty flag back to False to remove the dirty
marker on the editor.
6. Whenever an event happens on the editor, you need to mark the editor dirty. Therefore you
need to set the dirty.setDirty(true) as shown below
7. Run your code and you will see the desired output
