This would be really good to know.. Did you figure this out?
I'm trying to adjust the "Export Data" picker (this uses the pagebrowser.aspx) to include blocks. Ideally I just need it to be more like the "Set Access Rights" page tree which now includes the block libraries.
Let me know if you or anyone have any tips :)
I need to create a plugin which allows WebAdmins to select a block / blocks.
This functionality will be exposed as an Administrator plugin, and so I'm looking to see if there is a out-of-the-box way to select a block. I'm thinking the CMS7 Block equivalent of the old pagebrowser.aspx. Is something like this available, or do I have to roll my own?
