accordion: expanded-panels not working

[kgeis]

I am using BootsFaces 1.1.3 with PrimeFaces 6.1. I create an accordion with panels, and I set the expanded-panels attribute on the accordion. The corresponding panel always loads collapsed.

Example:

<b:accordion expanded-panels="panel2">
    <b:panel id="panel2" title="Panel 2">
    </b:panel>
</b:accordion>

I have encountered this same issue in 1.2.0 Snapshot. I am not using PrimeFaces. I believe the issue only occurs when the accordion is wrapped inside an h:form. If the form is removed the expansion works properly.

@kgeis did you try what @kvj2020 suggested?

[kgeis]

@TheCoder4eu, no, I did not try @kvj2020's suggestion. That would probably make the accordion work, but it would make my form not work...

I think a valid scenario is to allow accordions inside a form. I was commenting on what was causing the issue rather than identifying a work around. I would like to use the accordion inside a form. For a b:panel with an id='panel1' inside a form, the clientId is similar to 'j_id_s_1:panel1'. When the accordion is not inside a panel the clientId is 'panel1'.

Although I do not know the framework well enough, here are two options

1. In both cases the id is 'panel1'. Change AccordionRender.encodingBegin(...) line 104
   from: if (null != expandedIds && expandedIds.contains(_childPane.getClientId()))
   to: if (null != expandedIds && expandedIds.contains(_childPane.getId()) ?

2. if clientId contains ':' split it and use the second item from the split for the above contains check

@kvj2020 thanks for the suggested code (option 2) I just applied it and committed.

This issue is still reproducible in v1.4.2 - apparently expandedPanels/expanded-panels must contain client ids
