Is there any known limitation about saving data with Nintex workflow form ?
I have a form which has a Repeating section within another Repeating section. (i know bad design, but cannot be changed)
Typically the main Repeating section has about 80 rows and the child Repeating section generates around 20 rows in each parent section.
The form works well when there are only 10-15 items in the parent Repeating section.
The whole parent repeating section is connected to a multi-line text variable.
Even with 80 rows the form loads correctly (albiet takes 3-4 seconds) , but I get an error on clicking Save.
The error simply says "Sharepoint error"
you should provide details of your env.
eg. for SP 2013 on-prem there is documented limit of 8000bytes/item that you might encounter in your case
for 2010 there is the same limit.
could you check how many characters repeating section does save to the text field in case of eg 10. master items?
just to see what size it generates.
what about rest structure of your list? how many other are there? are there any other 'big' fields?
i tried using single character names for the sub controls just to reduce the size of the xml generated. But this is certainly not a scalable solution.
10 master items generated around 2000 characters
