Iframe does not get expanded automatically



Developer has created a section and added an Iframe inside a tab layout.They noticed that at runtime, the Iframe contents are not shown on tab.

Steps to Reproduce

  1. Add IFrame on a section.
  2. Expand tab with Iframe. Observe that Iframe does not show content.

Root Cause

The root cause of this problem is a defect in customer application code/rules.


The explanation for this behavior is as follows:

In the deployment scenario, a  non-pega webpage is embedded inside the iframe which does not seem to load when the iframe is invisible (hidden within a tab).

However the same configuration works for other webpage like Removing the webpage from I frame content resolves the issue.
Also, use the "defer load" option on the tab, as the iframe webpage seems to load when the tab body is visible.
