How to render html in custom web-panel in jira?

Egor Erofeev

Hello,

I can render html in CustomField, setting the wikirender for it. 

How can we display html (rendered) in custom web-panel using velocity template from Java variable?

What I've tried so far:

My velocity.vm: (i want "html" variable to be rendered using wiki-markup)

#disable_html_escaping()

#set($componentManagerClass=$constantsManager.getClass().getClassLoader().findClass('com.atlassian.jira.ComponentManager')) #set ($method = $componentManagerClass.getDeclaredMethod('getInstance', null))
#set ($componentManager = $method.invoke(null, null))
#set ($rendererManager = $componentManager.getRendererManager() )
#set ($renderer = $rendererManager.getRendererForType("atlassian-wiki-render"))
#set ($ircontext = $issue.getIssueRenderContext())
#set ($renderedText = $renderer.render($html, $ircontext) )

<span style="font-weight: bold; color: green;">$renderedText</span>

Any help will be appreciated, 

Regards.
