TASK: Understand <default mode="Hidden"/>

In this task you will understand the purpose of the <default mode="Hidden"/> property and how it affect the objectUI dialog boxes.

In this example we choose the Edit workstate dialog box in the EdAdmin4 application, defined in the EdAdmin4_Config.xml configuration file.

You will be able to perform this task only if:

•You already opened the edadmin4_config.xml file as explained in TASK: Open for editing one or more files with objectUI elements and ordered the view as explained in TASK: Display an ordered view of objectUI elements. If not so, return to those tasks and perform them first, and then return here.

1.Locate in the code the lines:

<objectUI name="editWorkstate" >

<default mode="Hidden"/>

2.Now, instead to delete the entire <default mode="Hidden"/> line, we will teach you how to deactivate it still keeping it in the code. Therefore, highlight the entire <default mode="Hidden"/> line and then on the Edit menu, point to Advanced, and then click Comment Selection.

3.The line looks like now green as on the following screenshot; it is commented out and not executed anymore.

4.Save changes and import them in database as explained in TASK: Save changes and import them in database.

5.CLose and run again EdAdmin4 and reopen the Edit workstate dialog box as explained in TASK: Get to know the Workstate entry dialog and recognize its fields.

6.Find the changes in the dialog box (on the left, the dialog with your changes made in this task; on the right, the dialog box as after the TASK: Understand useAttributesOrder property):

As you can clearly see, after you commented out the <default mode="Hidden"/> statement, and reloaded the configuration file in the database, the number of the fields in the dialog is not anymore the same as in the related section of the EdAdmin4_COnfig.XML. Now, the number of fields is the same as the number of attributes of the workstate object defined in the schema.

Conclusions

You learned that the <default mode="Hidden"/> property forces the dialog box to show only the attributes as specified in the configuration file. If you remove the property, of put it as <default mode="Normal"/> the number of fields cannot be controlled anymore by the configuration file, but all the attributes of an objects will be shown.

Important to remember:

•The changes of a configuration file are applied on the database only after you perform the reimporting as explained previously.

•The changes of a configuration are visible in a GN4 application typically only after its restart.
