Mashups in EMML : Advanced Mashup Techniques : Making Mashup Scripts Dynamic : Generating Mashup Scripts Dynamically
Generating Mashup Scripts Dynamically
 
<macro:externalDynamicEMML>
When the logic of a mashup must change dynamically, you need to create a mashup script on the fly and execute it. You can use the built-in executeDynamicEMML macro to do this. This macro is installed with the Presto Server and is available for use in any mashup script.
Note:  
You can use any EMML statement in dynamic mashup scripts, with one exception. You cannot invoke another mashup that itself is a dynamic mashup script.
The executeDynamicEMML macro allows you to generate a mashup script dynamically using the <script> statement and JavaScript or using Java classes. See <script> for more information on using JavaScript. See Using Java Classes in a <script> Statement for information on using Java classes in a mashup.
