Warning message DM10826 when running gendata (text merge area that can shrink/grow on image that cannot grow)

Question

I am currently converting from Documaker 11.3 to 12.2 While running GENDATA I get the following message:
DM10826:  Warning in TextMergeParagraph(): Attempting to use a text merge area that can grow, on the image <JACKETPAGE> which cannot grow. Processing will continue.
I have a text area in the JACKECTPAGE section that has the sizing option of "Can grow and shrink" selected.  This is because I have an imbedded tag in the middle of the text area. The "form section options" for the JACKETPAGE section that contains the text area does not have "Can shrink and grow" selected.  If I change the JACKETPAGE "form section options" to select "can shrink and grow" the warning message goes away.
Couple questions:
(1) What are the ramifications of selecting "can shrink and grow" on the form section option?  I really don’t want anything else on the form to move around.
(2) If there are no ramifications of selecting this option on the "form section options" there an easy way to find every section that has a text area that is flagged as "can shrink and grow" so that I can proactively flag the associated form(s) in order to eliminate these messages?
Thanks for whatever help that you can give on this!

The message is actually an old one, so I would be surprised if you are just now getting the message moving from 11.3 to 12.2. Unless it is perhaps because you were previously not using Studio model MRL and now you are.
The message indicates that a growing text area could potentially push objects out of the section boundary or even exceed the boundary itself - assuming you mapped in enough data. It is simply a warning.
If you know that your content can't really grow beyond your section or if you know and expect the result in case it does, then just ignore. Or if you know there is sufficient room for the content to grow within the section without overflowing the boundary (because you have white space at the bottom), then you could set the Can Grow on the section and prevent the message. Your choice really depends upon what you prefer.
However, if the growing text area can indeed push objects (or itself) outside the boundary with the data you map, then setting the Can Grow on the section will affect your output.When a section grows in size, this adjusts the position of the remaining sections on the page. If you don't allow that, you could have overlapping content if the text area pushed something outside the boundary of a section.
As for whether there is a way to globally set existing sections to grow, I don't think there is. The version you have now will automatically try to set the section to can grow when editing a section and you add a dynamic text area. However, you can still turn that off if you don't want it on. That does not affect existing forms or sections which you have in the library until you were to edit the sections and modify a text area.
