Extjs: increase size of a JsonStore
<p>I'm working on a software called "Group-Office" which uses the extjs-framework.</p>

<p>I've run into an issue that the so called <a href="http://dev.sencha.com/playpen/docs/output/Ext.data.JsonStore.html" rel="nofollow">data.JsonStore-Object</a> has a limit of 30 items. 
I couldn't find any method to increase it in the documentation.</p>

<p>I'd need help from somone who uses this framework on a regular basis or knows it better than me.</p>
