Enumeration in webapps

  • May 21, 2021

A webapp Page (v5 compatibility), Combo box input -> advanced settings Initialization: "Automatic via an enumeration" suggest we can use enumerations defined outside the webapp to populate a select element in our webpage's HTML.

 

Elements in schemas can use enumerations defined in the schema using attribute
enum="enumName"

 

Or, enum defined in different schema
enum="cus:schemaName:enumName"

 

Or, using a database enum
dbEnum="enumName"

 

However the settings for the combo box have a field "Enumeration Xpath", and however I write the reference to my enum, the select-element remains unpopulated.

 

The enum is of type system, and is working in inputforms using dbEnum="enumName" attribute. Can anyone share some light on how this is supposed to work, please?

Hello,

I agree this is a bit confusing.... But if we give a look a little closer, with the builtin webapps (for example 'deliveryOverview', 'webAppOverview' etc. by filtering webApp with "XML memo (data) contains 'contextOptions useContext="2" '), the answer is : the xpath refer to an attribute of the document schema ("Document type" defined into the General properties of the webapp) that use a enumeration.

For example, if you choose "nms:delivery" for your webapp document type, you can put "@state" into the xpath to populate the options with the nms:delivery:deliveryState enumeration values.

It's not impossible that you could use webapp context enumeration maybe ? If I see something I'll give you more precisions.

    Unfortunately, I do not have the default apps you refer to, et least I do not find them when setting a webapp folder to ("folder is a view"). As you suggest I load the enumerations defined in a schema in a script object before the page, and then initiate the combobox "via the context". This works fine for enumerations defined in the schema, but not for enumerations stored in the database. The idea for the client is to have a separate "product" emnumeration they can syncronise with another system without involving editing of schemas. When I try to load the enumeration using
