Description David Edmundson 2011-05-20 14:20:43 UTC

Version:           git-latest (using KDE 4.6.3) 
OS:                Linux

The accountFilterModel contains a really ugly hack that invalidates the filter each time any row changes. This is not only slow, but a sign of something else being fundamentally broken.

This is needed as otherwise the filter doesn't seem to apply presence filtering when using the group model (or flat-proxy-model).

When using a groups model, the dataChanged() signal appears to emit the wrong indexes (?). When asking for presences it's returning invalided QVariants.

Reproducible: Didn't try

Found it.

In ProxyTreeNode a signal is emitted when data changes.
A treenode should send itself as a paremeter of the signal, this is used to build the index.

The buggy code:
    connect(sourceNode,
            SIGNAL(changed(TreeNode*)),
            SIGNAL(changed(TreeNode*)));

sent the id of the real ContactModelItem* in the accounts model, not the proxyModeItem in the groups model. This caused messed up indexes to be created which weren't sure which model they were from.

Will push fix to RB tomorrow.
