Set global variable action

You can set global variables to be used by other objects within your project and also by other projects in the .ear. When you set a global variable, you can specify a name or select an existing global variable name from the drop-down list for the Name field. If you select an existing indexed global variable, click Advanced to specify how to handle the setting of the value. The following options are available:

Overwrite the existing value with this new value
Overwrite the existing value with this new value, starting at the specified index
Append this new value after the last index of the existing value
Insert this new value into the existing value, at the specified index

For the two options that use a specified index, you must enter the number of the index in the Index field.

For an example of how a variable value is set based on the option you select, see Extract global variable action.

If you are setting the global variable to a fixed value, type the value in the entry field.

If you are setting the global variable to a calculated value, you specify the operands to be used and the operation of the calculation. The operands can be either fixed values that you enter into the field, or you can use the values of existing global variables for the calculation. If you use an existing indexed global value, and you want to specify an index of the variable to use as the operand, click Advanced. Enter the number of the index in the Index field.

Selecting the Shared check box will allow the global variable to be shared.
