Bug: DataSource cacheAcrossOperationIds attribute

[tgilbert]

Hi,

I wanted to switch the cacheAcrossOperationIds datasource attribute to false (and use the client-side caching facilities for 1 operation ID only). I've read the documentation and have set up the other attributes to the correct values.

I wanted to report that if I turn off this attribute by setting it to "false" in the .ds.xml, it does not work.

I checked the value in the client by calling getCacheAcrossOperationIds() on the datasource and got the following exception:

com.google.gwt.dev.shell.HostedModeException: invoke arguments: JS value of type string, expected boolean
	at com.google.gwt.dev.shell.JsValueGlue.get(JsValueGlue.java:100)

	at com.smartgwt.client.data.DataSource.getCacheAcrossOperationIds(DataSource.java:285)

On the other side, if "hardcode" this attribute in the client as well by calling:

ds.setAttribute("cacheAcrossOperationIds", false, true);

Then, getCacheAcrossOperationIds() does work and the whole cache mechanism works as I want.

Is it possible to fix this so that we can fine tune the caching features in the xml instead of in the code ?

Many thanks,

Thomas

We'll fix this, but a quick workaround is to be explicit about type in your XML:

<DataSource ...>
     <cacheAcrossOperationIds xsi:type="boolean">false</cacheAcrossOperationIds>

A fix has been committed, you will find it in the next nightly build.

Thanks,
