InfoPath Dev

Hi folks,

I was trying to delete the current row in a repeating table using a button in the row itself with an action to run the command:

concat("Delete /xpath=/my:ElectronicChangeControlForm/my:TaskSection/my:TaskTable/my:Task[", count(preceding-sibling::my:Task) + 1, "]")

Which of course tested ok in the InfoPath client, but when I deployed it to SharePoint didn't work.

Any ideas how to do this in a webform? Tried a few solutions with no luck

Did the qRules Error field show an error?  Have you double-checked that the button has Postback set to Always?

No, the postback happened correctly, and the row was deleted BUT the preceding sibling axis evaluated as zero, so the +1 then always deleted the first row. I believe this is because it doesn't evaluate correctly in browser forms

Alright, I've resolved this.

Essentially, the expression above won't work in a browser form (the count will give 0, then add one, deleting the first row). However the following will produce the desired behaviour in a browser form: 

concat("Delete /xpath=/my:ElectronicChangeControlForm/my:TaskSection/my:TaskTable/my:Task[", count(preceding-sibling::*[local-name() = "Task"]) + 1, "]")

This is rather puzzling.  We've used qRules delete in browser forms and had success with it.  I'm surprised that you ran into this behavior, but glad that you found a resolution.

hey Jimmy, The problem isn't with delete - that works perfectly in browser forms.

The problem is that preceding-sibling::my:Task doesn't work in browser forms, so the above concat'd command won't work to delete the current row as it's recommend for in this thread. Instead it needs to be changed to preceding-sibling::*[local-name() = "Task"]) to work in a browser form.
