Resolution: Won't Fix
Affects Version/s: 7.0.0 DXP FP47, 7.0.X, Master
Fix Version/s: None
Component/s: Frontend Infrastructure > UI Taglibs
aui:form taglib is adding an input hidden field which id is based on portlet namespace, hence if we add two aui:form inside the same portlet, we'll have a duplicated id.
Steps to reproduce
1.- Start Liferay
2.- Add Dynamic Data List Display portlet to Welcome Page. (We'll use this one, but any portlet with two aui:form's wil lhave the same behavior)
3.- Go to Configuration in that portlet.
4.- Inspect DOM and find "_com_liferay_portlet_configuration_web_portlet_PortletConfigurationPortlet_formDate"
You only get one result, so there are no duplicated IDs
You get two results, so there are duplicated IDs
