Description

According to LPS-5935, the aui:panel and aui:tool taglibs work together to pull tool buttons on the panel bar. aui:panel works fine, but after adding an aui:tool tag inside the panel a stack trace is issued and the panel fails to render properly.

Steps to reproduce:

  1. Create an AUI panel with a tool 
    <aui:panel collapse="true" id="myPanel" label="My Panel">
<aui:tool icon="refresh" id="refreshTool" handler="this.set('bodyContent', defaultText);" />
<aui:tool icon="close" id="closeTool" handler="this.hide();" />

Content here...
</aui:panel>
  2. Deploy the portlet
  3. Add the portlet to a page
  4. Observe that while the content is present, the panel is not rendered and neither is the tool.
  5. Check the logs and observe a stack trace

Hello everyone! We are in the process of removing component "Liferay TagLib" from LPS issues that contain more than one component. For issues that only have "Liferay TagLib", we plan to move to them to "Tools > Portal Taglibs". In the end, "Liferay TagLib" will be deprecated. Please make the necessary adjustments to your filters. Thanks!
