315647 - tree.view property turns up null

Status: RESOLVED WONTFIX

(Core :: XUL, defect)

Sometimes the "view" property of a XUL <tree> element **turns up null** after running the following code where ndTreCdt is a DOM node reference to a populated <tree>.

ndTreCdt.datasources = uriRequest;
ndTreCdt.builder.refresh();
ndTreCdt.builder.rebuild();

The is strange because I can see contents rendered in the tree based on my <template>

When I went to about:config and switched javascript.options.strict to "true", the problem went away and I haven't been able to reproduce this anomally since.

Nothing shows up in the JS console. This code exists in a try/catch block but no exceptions are thrown.

I don't think anyone is going to work on this given the plan to remove the XUL "tree" widget (bug 1446335).
