Re: How do I insert on repeating groups?

Okay, so what we found was that the insert on a nested repeating group was likely causing events on the parent group to fire. Using a helper field to prevent those rules on the parent from firing when the child changed resolved the issue. This was only happening in Browser, not in Filler - like I mentioned, I've seen event bubbling in the browser cause this type of issue before (often with attributes in secondary data sources).

Feel free to attach the form to a reply or send it to me if you'd like me to take a quick look.

I confirmed the logic of the rule in filler. I've changed the count to 1 for all the repeating groups and still get this error: An error occurred in the form's code. The number of calls to the Changed event for a single update in the data exceeded the maximum limit. I then changed the count = 2 and this is the error: An error occurred in the form's code. The number of calls to the Changed event for a single update in the data exceeded the maximum limit. Default values, rules or code may be running in an infinite loop. To prevent this, ensure that the default value, rule action or event handler does not update the data which causes the same rule action or event handler to execute.

Yes, I understand that this works in filler and not in browser.

Is the failure the looping error? Or something else?

I have a delete and then the insert. The delete executes 100% (tested this with insert disabled). I'v set a rule condition on the insert which to test that the repeating group does not exist. Again in filler this works and in browser the second instance of the repeating parent group fails.

What I've done when I've had an issue like this (works in filler, looping error in browser) I try to find a way to set a condition on the rule that will prevent bubbling - so, for example, maybe the rule only runs if a particular field is blank in the inserted group... sometimes I use a helper field that I set to a specific value and use it to try to prevent a rule for executing more often than it should. You may want to set a field's value to its own value concatenated with whatever the qRules Command node has been set to, so you can see if something is causing a command to be executed multiple times.

You may want to temporarily disable any rules on any fields inside the group to help you start tracking down where the issue is occurring....

No attributes anywhere. The insert rule is on the parent though.

Do you have any attributes in your repeating group? In Browser, I've had attributes trigger rules on the parent group. Very Icky.

Why would it work 100% in Filler but not in Browser?

Sounds like it's exactly what the error suggests - that the insert is causing a rule or default value to run repeatedly in a loop. It's impossible to tell you how to fix this without seeing your form.

Hi Jimmy, sorry It only fixed my problem in Filler, not in Browser: This is the command that I have Insert /parent=/my:myFields/my:grpSupport/my:Support[2]/my:grpSupportCFH /child=my:CFH /count=2 /xpathsrc=/my:myFields/my:grpSupport/my:Support/my:grpSupportCFH/my:CFH In filler it works perfectly, but in Browser it failed with these errors and a Correlation ID: An error occurred in the form's code. The number of calls to the Changed event for a single update in the data exceeded the maximum limit. and Default values, rules or code may be running in an infinite loop. To prevent this, ensure that the default value, rule action or event handler does not update the data which causes the same rule action or event handler to execute.

Excellent! the /xpathsrc fixed my problem! Thank you Jimmy!

Re: How do I insert on repeating groups?

As a rule of thumb, I would suggest structuring your data source so that all repeating groups have their own exclusive non-repeating parent. In your case it would be something like:

myFields

|- Group1Parent

|- Group1 (repeating)

|- Field1

|- Group2Parent

|-Group2 (repeating)

|-Field2

When you want to use Insert on a specific nested repeating group, like in your case, you need to specify the xpathsrc parameter. Please try this:

Insert /parent=/my:myFields/my:Group1[1] /child=my:Group2 /count=2 /xpathsrc=/my:myFields/my:Group1/my:Group2

Hi,

Could you explain more about your schema, or perhaps even attach a screenshot of the data source or the form itself? I'm having a hard time visualizing which are the repeating groups, whether all repeating groups have a parent container group, etc.

Thanks!
