It appears that the DA sample client doesn’t request items on a branch unless the server sets the ‘OPC_BROWSE_HASCHILDREN’ bit of the dwFlagValue in the OPCBROWSEELEMENT structure when processing a OPC 3.0 Browse() request. Is this a bug or do I not understand the usage for ‘OPC_BROWSE_HASCHILDREN’.
The description says:
If the first bit is set (OPC_BROWSE_HASCHILDREN), then this indicates that the returned element has children and can be used for a subsequent browse.
When my server has a branch with items but no child branches, I have to set the OPC_BROWSE_HASCHILDREN bit or the sample client can’t show the items.
