    <p>The problem is outside of your code snipplet. Besides i don't really know what you're trying to achieve with this code. It does absolutely nothing besides wasting time and calling <code>getCurrentLengthUnit()</code> if you are in one of the cases and throw an exception otherwise. All assignments write to LOCAL variables and do not have effects on any other variables.</p> <p>Your code has the same effect as the following implementation:</p> <pre><code>public static void getMinMaxValuesForNumberPicker(LengthType type, Integer min1, Integer max1, Integer min2, Integer max2) { switch (type) { case BODYSIZE: case CIRCUMFERENCE: case WRINKLE: case DISTANCE: getCurrentLengthUnit(); break; default: throw new RuntimeException("getMinMaxValuesForNumberPicker für " + type.name() + " nicht implementiert!"); } } </code></pre> <p>So either you call <code>getMinMaxValuesForNumberPicker</code> from <code>getCurrentLengthUnit</code> or you expect that your assignments have effect on the variables that are not local to your function. Writing to the parameters doesn't make the changes visible to the calling function:</p> <pre><code>Integer a=-1; Integer b=-1; Integer c=-1; Integer d=-1; getMinMaxValuesForNumberPicker(LengthType.BODYSIZE , a, b, c, d); // a, b, c, d are still -1 here although you never assigned -1 and "assigned" null to the parameters in getMinMaxValuesForNumberPicker // The parameters are just copies of the adresses of a, b, c and d and not aliases of a, b, c, and d </code></pre> <p>(I guess you didn't use the debugger to go through the code step by step. This may have caused some confusion.)</p> <h2>Note: Question has been edited since the code has been posted</h2>

    1. COthis does not have to do anything with the problem... I use a custom class with an internal int variable anyway now... didn't think of this at first... nevertheless, your statement is correct, but it does not have to do anything with the problem... Even if my code relating to integer would do nothing, that does not explain the weird behaviour.... PS: I do debug step by step, otherwise I could not have been able to add my comments 1) 2) 3)

    3. COAdd a breakpoint to the line `switch(type)`, I'm sure you visit this breakpoint before visiting 3).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
