Frame communication does not work when URLEncryption is enabled
SA-57360
Summary
On enabling URLEncryption, the frame communication does not work correctly. This affects the Web Mashup resizing and user clicks within the content.
For example:
A link on the initial mashup page should open the work object within the mashup space. However, when URLEncryption is enabled, the work object displays in a popup window. With URLEncryption disabled, the work object displays correctly within the Mashup.
Error Messages
Not Applicable
Steps to Reproduce
Enable simple Mashup with URLEncryption.
Root Cause
To enable URLEncyrption, the Mashup must use an HTTP POST on the initial gadget load. This is accomplished with the following JavaScript:
pega.web.config.cmd.pegaAction={"httpMethod":"POST"};
When using this, the UI does not set isWebMashup to true on the pxThread page. Hence, the window.postMessage methods at the UI level do not run correctly.
Resolution
Perform the following local-change:
1. Include the below Script Block: <script>
pega.web.config.encrypt=true;
pega.web.config.cmd.pegaAction={"httpMethod":"POST"};
</script>
2. Set the Mashup Div element parameters attribute as below:
Add isWebMashup:'true' to data-pega-action-param-parameters Mashup div attribute.
For example:
data-pega-action-param-parameters="{paramA:'valueA',isWebMashup:'true'}"
3. Set the Pega Platform Server settings as below:
prconfig/initialization/urlencryption/default = true
prconfig/initialization/submitobfuscatedurl/default = optional
