What are Hash Variables?
...
| English |
|---|
Hash variables in Joget are placeholders used to dynamically display data within applications. They allow users to insert dynamic content without hardcoding values, which enhances flexibility and customization. Hash variables can fetch and display data from various sources such as forms, workflows, and the system itself. They promote customization and flexibility by avoiding hardcoded values, ultimately improving the user-friendliness of Joget applications. |
A hash variable is a special hash-escaped keyword that can be used in :

A new #process.recordId# hash variable was introduced in Joget DX to retrieve the process database table id (or primary key value) which will return the UUID id value of the process record stored in app_fd_[form_table_name], if the General Settings > Run Process Primary Key is set to "UUID". If the "Run Process Primary Key" option in General Settings is set to "Process instance ID", the "#process.recordId#" will return the same value as "#process.processId#".

| Prefix | userviewKey |
| Description | Userview Key Hash Variable is used solely for the purpose of accessing the current UI key's value. Typical use case for this hash variable are:- - Filtering a List based on UI Key.
- Preloading certain form data field (e.g. subform) in a Form or Form part of a process flow based on UI Key.

Expression Hash Variable
** for "datalist.col.xx.ID.column" variables, the "column" parameter refers to the order of the column in the list starting from 0. hence, to refer to the first column in a list called list_f1, your hash variable would look like this : #datalist.col.sum.list_f1.column_0
** the column are counted from 0, and does not include the default checkbox included in list tables

This is a new feature in Joget DX 8. |
| Name | Description |

| Prefix | uiListCount |
| Description | The uiListCount hash variable is primarily utilized to retrieve the Datalist or Inbox menu count value. |
| Attributes | - #uiListCount.MENU_ID#
- #uiListCount.UI_ID.MENU_ID#
|
| Scope of Use | - All components within the App except UI Permission.
| Warning |
|---|
uiListCount cannot be used inside UI permission. This is due to:
1. UI permission contains a uiListCount hash variable
2. uiListCount Hash requires UI to load to get the count
3. In order to load the UI design, the UI permission will be called. It goes back to step 1.

| Sample Attributes | See examples below, based on the usage within the default CRM application: - #uiListCount.MENU_ID# where MENU_ID is the id of the menu in your Userview for Datalist or Inbox (Example usage: "#uiListCount.proposal_inbox_list#")
- #uiListCount.UI_ID.MENU_ID# where UI_ID is the id of the Userview (Example usage: "#uiListCount.crm_userview_sales.proposal_inbox_list#")
