Hi Isomorphic,
please see this minimal testcase (based on builtInDS) showing a unnecessary fetch even though setAutoFetchData(false) is set.
The fetch results in a DS Console warning "13:05:05.810:XRP0:WARN:The ResultSet's cache was invalidated while the following request was outstanding".
Tested with v9.1p_2014-06-29 in FF26 DevMode.
BuiltInDS.java
Change to animals.ds.xml:
Interesting observation 1:
In RPC-Tab of the Dev Console, it is for the unnecessary fetch:
sortBy:[
"-commonName"
]
while it is
sortBy:[
"-scientificName"
]
for the queued fetch.
Interesting observation 2:
If you remove "setFields(scientificName);" (so no setFields() for that ListGrid), the bug is gone.
Interesting observation 3:
If you move "vL.draw();" above the RPC-Manager-block, the bug is gone.
Unfortunately I don't have these options in my app.
Best regards,
Blama
