[CONFSERVER-81454] HTML Script elements with content of length greater than 4000 characters, are corrupted when rendered within a Macro
My previous comment was somehow deleted so I try it again.
Your (Atlassian support) asked me to comment here, after my question could not be answered:
"I cannot say if we hit the 64k limit. How can I figure out?”
Our problem is, we don’t know what exactly counts towards this limit, we are just a customer. What we do is to wrap tables with stiltsoft macros. TableTransformer, TableExcerpt, TableInclude…
Does content, enriched with hyperlinks (generated by TableTransformer) count as well?
Best Regards,
Oskar

We have an ongoing incident with one customer, where these CDATA tags were still injected in unexpected places (using Confluence 8.0.3)
We have analyzed the HTML they have shared with us and indeed, the page is pretty JS heavy, but the 3 largest blocks are
5243
12737
27653
characters. Certainly under the 64K limit what you have mentioned. And those are not generated by our app - the largest we have is 4053 characters. True that the page has 441 script blocks (as it is an aggregated page that uses data from multiple others)

Hey 6dfd011db329,
Mostly fixed is an improvement at least.
The limit applies to the contents of each script element.
Do you have a finger to the wind idea of how many characters you might need for a given element?
We can build some wiggle room in on our end.
Thanks,

Hi James
We have see this "mostly fixed", but still have some customers who are experiencing this issue on large forms they have
When you say the "merge size" is now 64000 characters, does it mean the contents of a script element should be less than 64000 or is it a limit for all script elements generated by the velocity template? In other words - what do you mean by the "merge size"
Alex
When will this be fixed, our Confiforms is still broken in 8.1.3 - and we are u nable to deploy to production -
This is a heavy blocker
