I see a discrepancy here between my tests and what you have reported here. You've indicated that this happens in Windows 7, yet my tests with Windows 7 and Windows Xp show that the repeating field slides/shrinks correctly.
Did have an idea for a simpler work around:
Have you tried using multiple copies of the field, the first formatted to show repetition 1, the second formatted to show repetion 2 etc. Did that work?
That method eliminates the need to define extra calculation fields in order to get things to slide...
Definitely not working properly in my VMWare Windows 7 instance (see attached screenshot). I don't have XP to test.
Also, I am using the method "Show repetitions 2 to 2" (for example) for each of the field repetitions. Only one repetition is being shown. Sliding appears not to work when it's repetition 2 or larger. I've tested this for Text and Container fields.
The sample file (https://dl.dropbox.com/u/2698139/Proof/FM%20Forums/Sliding%20Test.fmp12.zip) demonstrates the issue as well as my workaround (which is to calc the repetitions into single-repetition fields for use on the layout).
Hmmm this is a slightly different issue than that documented in the other report. In the other, they are using a single field object with multiple repetitions instead of multiple copies of the same repeating field with each set to a different repetition. I was testing the original thread's issue, not this one.
PS. for reasons that have nothing to do with this bug, I use repeating fields very rarely as there are other more flexible alternatives for most situations where you might use a repeating field--which does not change the fact that this is a bug that should be fixed.
Thanks. Let me know if you need more info.
I can reproduce this in XP once I use multiple copies of the same field with each set to a different repetition. I'll PM one of the TS people I know to take an official look at this one to make sure that they don't just class it as part of the original bug the way I originally did. (The other bug is mac only, this one is cross platform.)
Thank you for your posts.
The original link that PhilModJunk reported shows that it occurred under Mac OS X, and our online support person tsturtle only tested under Mac OS X. However, our Testing department was able to reproduce the issue under both Mac OS X and Windows. In essence, repeating fields that start under a different number than 1 do not slide properly.
I have attached your posts to the original report, and when more information becomes available, I will let you know.
Updating the known bugs list to correct this error on my part...
