PagingButtons can't find the pagingPane on XML loading

[Sorax5]

Hello, I recently wanted to test the XML feature of the plugin, but I think I found a problem with the loading of Paging.

For reference here is my XML:

<chestgui title="Dressing Room" rows="6">
    <patternpane x="0" y="0" length="9" height="6">
        <pattern>
            <row>100000001</row>
            <row>111111111</row>
            <row>100000001</row>
            <row>100000001</row>
            <row>100000001</row>
            <row>111111111</row>
        </pattern>
        <binding char="1">
            <item id="BLACK_STAINED_GLASS_PANE" field="backgroundItem" />
        </binding>
    </patternpane>

    <paginatedpane x="1" y="0" length="7" height="1" populate="populatePartEnum" id="partenum"/>
    <paginatedpane x="1" y="2" length="7" height="3" id="clothproduct" populate="populateClothProduct"/>

    <pagingbuttons x="0" y="0" length="9" pages="partenum" />
    <pagingbuttons x="0" y="3" length="9" pages="clothproduct" />

</chestgui>

As you can see, I did what the wiki asked me to do, i.e. to put an Identifier to the PagingPane and to put this reference in PagingButtons.
Except that I got this error on loading:
Paging buttons pages reference is invalid

Which, after reading the source code, comes from the fact that PagingButtons can't find the identifier of the associated PagingPane.

After a number of tests, I came to the conclusion that the problem was with “populate”. In fact, if I remove these attributes, I get no errors (and no items, since I can't hydrate my GUI).

I think that populate blocks the recording of the pane identifier (or does so after the buttons are loaded), which means that the buttons can't find the associated Paginated Pane.

Is the error mine or is it a problem with the library?
