Issue Summary

The contributing factors to this bug have not yet been isolated. Please refer to the reproduction steps below.

Steps to Reproduce

In General:

1. Create a plugin
2. Define a Struts Action which maps to a Velocity Result
3. Define a getter method on Action class whose name ends with 'html' and returns a String
4. Have the Velocity template render a Soy template, where the 'value' parameter is obtained from the aforementioned method

   #set($templateParameters = {
       "type": "textarea",
       "labelContent": "$i18n.getText('user.macro.template')",
       "name": "userMacro.template",
       "id": "userMacro_template",
       "value": $!action.templateHtml,
       "rows": "20",
       "cols": "80",
       "extraFieldClasses": "max-textarea",
       "description": "$i18n.getText('user.macro.template.desc', [$docBean.getLink('help.user.macro.templates')])",
       "required": "$i18n.getText('required.field')"})
   $soyTemplateRendererHelper.getRenderedTemplateHtml("com.atlassian.auiplugin:aui-experimental-soy-templates", "aui.form.field.soy", $templateParameters) 

5. Browse to the Action and trigger rendering of template

OR

In Confluence Core codebase:

1. Edit confluence-core/confluence-webapp/src/main/webapp/admin/macros/usermacro-form.vm
2. Replace $!templateHtml with $!action.templateHtml
3. Visit /admin/addusermacro-start.action

Expected Results

A form input field whose default value is the String returned by the previously defined method.

Actual Results

Expected value is prepended by

{annotationCollection: [{}], annotations: [{}], collectionInheritableAnnotations: [{}], declaredAnnotations: [{}], description: Annotated value: 

 and appended by

; Annotations: [@com.atlassian.velocity.htmlsafe.HtmlSafe()]} 

Workaround

Instead of passing the value using:

$action.methodNameHtml

Use the OGNL shortcut:

$methodNameHtml
