Setting values depending on alert dialog answer

[Javier Echaniz]

Hi, i have an alert dialog dispatched when a value changed and i would like to change values and clear repetitions depending on the dialog's answer.

I use 2018 version, and i don´t know what to do or what i'm doing wrong. 

This is the part of the code that would do the operations.

Could you  give me some help?

Thanks in advance.

Hi Javier,

`<fr:repeat-clear>` is part of the action syntax (see link below), which cannot be used inside a `<fr:positive-choice>` or `<fr:negative-choice>`. For context, is this for a form you created with Form Builder, or is it for XForms you wrote yourself? Also, what triggers the dialog to appear?

Hi Alex,

the form has been created with Form Builder (except for the action and dialog message, what i wrote myself) and i have no triggers in the code for the dialog to appear, it appears when the field "cuerpo" changes its value.

Hi Javier,

Thank you for the additional details.

- Is your dialog box showing?
- We need to find a replacement for `<fr:repeat-clear repeat="iteracionesLink"/>`. It will most likely be a `<xf:delete ref="...">`. To determine exactly what to delete, I recommend examining the data structure using the XForms inspector.
- You shouldn't need the `fr:control-setvalue` since you are already setting the value elsewhere. I recommend removing these instances. At best, they won't have any effect, and at worst, they could cause problems.

Hi Javier,

Were you able to replace `<fr:repeat-clear repeat="iteracionesLink"/>` with `<xf:delete ref="...">` based on your data structure? If not and you're still working on this, let me know if I can help.

Hi Alex, sorry for not answering.

I've been moved into another project and i've been told not to continue with this issue. As soon as i could have a little rest i'll try to guess about this dialog.

Thanks.

Javier.

Hi Javier,

No problem at all - thanks for letting us know. If you do get a chance to revisit this dialog issue in the future, feel free to reach out and I'll be happy to help figure out the right approach with the `xf:delete` replacement.
