Malformed URL with setValue

Hi,

I have a pageflow that defines three edit pages:

<page id="edit-1" path-info="..." view="..." default-submission="...">
<setvalue parameter="field-on-page1" ref="/form/edit-1/field-on-page1"/>
<setvalue parameter="field-on-page2" ref="/form/edit-2/field-on-page2"/>
<setvalue parameter="field-on-page3" ref="/form/edit-3//field-on-page3"/>
<action ... next/>
</page>
<page id="edit-2" path-info="..." view="..." default-submission="...">
<action ... goto edit-1/>
<action ... next/>
</page>
<page id="edit-3" path-info="..." view="..." default-submission="...">
<action ... goto edit-1/>
<action ... goto edit-2/>
<action ... next/>
</page>

This allows prefilling using url parameters when starting the form. However, when I don't fill in the field on edit-page 1, go to edit-page 2 and then go back to edit-page 1, I get an exception from NetUtils#decodeQueryString:

Malformed URL: %24instance=X2ztn[...]Aqjf0A%3D&field-on-page1=&field-on-page2=&field-on-page3=

The reason for this exception seems to be that Orbeon adds unescaped url parameters to the url with empty values. This exception doesn't happen when going from edit-page 3 to edit-page 2, so it seems that the bug is triggered by a xforms:send to a page with setvalue's. Weirdly enough, this works (except that it obviously doesn't prefill the fields for later edit-pages):

<page id="edit-1" path-info="..." view="..." default-submission="...">
<setvalue parameter="field-on-page1" ref="/form/edit-1/field-on-page1"/>
<action ... next/>
</page>

I don't understand why it would matter if I do a setvalue for a field from the second or third edit-page. Is this a bug or am I using Orbeon incorrectly?

Regards,

Wouter Zelle

It is hard to see exactly what is going on without being able to run the code. Could you create a minimal "app" that we can use to reproduce this? I.e. a few files that you put in your own directory under apps and that we can just put in our environment to reproduce this.

Re: Re: Malformed URL with setValue

Hi Alessandro,

I've attached a small app with two edit-steps and a view-page. There are two street fields, called "street" for edit-page 1 and "street2" for edit-page 2, that can be prefilled. There are also two housenr fields that cannot be prefilled.

Test1:
- Goto /orbeon/address/?street=a&street2=b
- Click on Next until you get to the summary page
- Click on Previous until you get back to the first page
> This works perfectly

Test2:
- Goto /orbeon/address/?street2=b
- Click on Next until you get to the summary page
- Click on Previous until you get back to the first page
> This crashes when going back to the first page

Test3:
- Goto /orbeon/address/?street=a
- Click on Next until you get to the summary page
- Click on Previous until you get back to the first page
> Strangely enough, this works perfectly

Thank you for the test case! I'll investigate this as soon as I get an chance and get back to you here (if someone doesn't respond to you before that).

Re: Re: Re: Malformed URL with setValue

Alex,

I managed to get prefilling to work by doing it in the view. On the xforms-model-construct-done event, I do xforms:setvalue's to do prefilling. However, I'm still interested in knowing why it won't work correctly in the pageflow.

Regards,
