## Description

The Value Field precondition compares the current value of a field against a predefined value. It can compare strings, numbers, or option IDs. For select fields, you can compare either by string or option ID. The ID may be preferable, as the label of an option may change over time; the ID remains constant. If a field can have several values (like components), only one of the values is required to match.

## Configuration

You must specify the field and value that will be the prerequisite for the check.

If you choose the comparison type String, only '=' and '!=' are valid options.   
You may leave the value empty and choose comparison type '!=', to tell that a given field is required for the condition.   
For date fields without time, use the format 'yyyy-MM-dd' for values, and for those with time 'yyyy-MM-dd HH:mm'.   
Example February 12th 2014: 2014-02-12, at 8:05 AM: 2014-02-12 08:05, at 4 PM: 2014-02-12 16:00.

### Example

A workflow is configured so the 'Start Progress' transition has the 'Value Field' check set to 'MultiSelect' = '10021' (option ID). A user viewing an issue in that workflow will not see the 'Start Progress' transition unless 'MultiSelect' has at least the option with ID '10021' chosen.

## Supported field types

JSU supports various field types, including system fields and custom fields. However, not all field types are supported, and not in all combinations. We aim to cover the most important field types and continuously add and improve support for different field types. Some custom fields of other third-party apps might never be supported.
