Found out that this is not the only issue with sharing code from the data
package between Sencha Touch and ExtJS 4.
ProtocolProxy inherits from src/data/proxy/Server.js and in Ext JS 4 we have
something like:
operation.commitRecords(result.records);
operation.setCompleted();
operation.setSuccessful();
whereas in Sencha Touch this reads (so there is no commitRecords function etc.
on operation):
if (operation.process(action, resultSet, request, response) ===
false) {
this.fireEvent('exception', this, response, operation);
}
Should we try and make our data package work with both, or should we give up
altogether on sharing code?
Thoughts?
Best regards,
Bart
