Message:

• added ajaxOnChange parameter support for <wizard:...> elements. ajaxOnChange now performs an ajaxSubmit to the current form. Usefull for handeling select changes and dynamic forms. When using the ajaxOnChange attribute you can also add the 'url', 'update' and 'afterSuccess' parameters. In your webflow the action is triggered that you put in the ajaxOnChange argument.
• example:

<wizard:templateElement name="template" description="Template" value="${study?.template}" entity="${dbnp.studycapturing.Subject}" ajaxOnChange="switchTemplate" url="[controller:'wizard',action:'pages']" update="[success:'wizardPage',failure:'wizardError']" afterSuccess="onWizardPage()" >

The template to use for this study

</wizard:templateElement>

Will submit on change, triggering the 'switchTemplate' action in your current webflow:

on("switchTemplate") {

println params

}.to "study"
