InfoPath Dev

Hi All, I have InfoPath 2013 form, the form has a multitext field. The field should contain information like - 1234567; 1234567; 1234567; 1234567; I need to make sure that user enters all numbers with 7 digits separated by '; ' semi comma and space. Can you please let me know how to achieve this.

Is this a list form? Do you mean the field is multi-line? If so - is it plain text in the list settings?

Yes its a list form and a plain multiline field. I used this - ([0-9]{7}(;\s[0-9]{7})*;). it works but as soon as I enter a pattern that doesnt match this regex it shows an error ( which is fine) but even after correcting the text in the field this error doesnt go away. Once an error appears it stays irrespective of the entry in text field.

Hmmm. I don't know how helpful this is, but I just tested this in a list form of mine. I checked in preview and in the published form, and in all cases the validation worked as expected. The field was marked invalid unless I had 7 digits, followed by a semicolon and a space for any additional numbers.

Thanks for your response. I forgot to mention this is an auto populated field, which user can edit later. I tried it on regular field and it works too. 2 things that pop to my mind : --Can it be some sort of caching issue? Once the error appears it doesn't go, but as long as user is entering correct data it works. --Can this issue be because its auto populated? Please let me know if you feel I am missing out something.

So - by auto populated, you mean it has a default value? Or is it being set by a rule?

It has default value based on another field. Something like this in the default value - eval(eval(Title[Test= Value], 'concat(., "; ")'), "..") The 'Title' and 'test' coming from another list using data connection and 'Value' coming from another column in the form.
