Question

How do you fix a names mismatch problem, if the client-side names are keywords or reserved words in the server-side language you are using?

The DOJO JavaScript toolkit has a QueryReadStore class that you can subclass to submit REST patterned queries to the server. I’m using this in conjunction w/ the FilteringSelect Dijit.

I can subclass the QueryReadStore and specify the parameters and arguments getting passed to the server. But somewhere along the way, a ‘start’ and ‘count’ parameter are being passed from the client to the server. I went into the API and discovered that the QueryReadStore.js is sending those parameter names.

I’m using Fiddler to confirm what’s actually being sent and brought back. The server response is telling me I have a parameter names mismatch, because of the ‘start’ and ‘count’ parameters. The problem is, I can’t use ‘start’ and ‘count’ in PL/SQL.

Workaround or correct implementation advice would be appreciated…thx.

While it feels like the wrong thing to do, because I’m hacking at a well tested, nicely written JavaScript toolkit, this is how I fixed the problem:

I went into the DOJOX QueryReadStore.js and replaced the ‘start’ and ‘count’ references with acceptable (to the server-side language) parameter names.

I would have like to handled the issue via my PL/SQL (but I don’t know how to get around reserved words) or client-side code (subclassing did not do the trick)…without getting into the internals of the library. But it works, and I can move on.
