    <p>This question is related with one I asked before <a href="https://stackoverflow.com/questions/13324582/working-with-multiple-layers-kineticjs/13336373#13336373">here</a>. I'm currently using KineticJS 4.0.5 and I'm using multiple layers to display some shapes with different properties. Since I need to change the layers contents frequently I'm using removeChildren to remove a layer content, but it seems that removeChildren also removes the events associated to childrens. I would like to remove the layer childrens without removing their events because I may have to add them to the layer again.</p> <p>I tried to set the layer.childrens attribute equal to an empty Array instead of using the removeChildren function. At first it seemed to work but on some cases, some weird things happen :/ Some shapes disappear and the only way to get them back is by setting their Z index. I think the main problem with this approach is related with some properties that must be reseted when contents are removed from the layer, but I don't know which are they.</p> <p>I also tried to set the events again on each shape before drawing them but it doesn't work... They remain static on the screen... I event tried to use the setDraggable(true) on all shapes before drawing them but no luck... Do I need to create the objects again and apply the events to them again each time I want to redraw a layer with shapes I used before? Or would it be a good approach to store layers for each screen on my application? (I can have a lot of different screens, which would result in a lot of layers and only one would be displayed at a time...)</p> <p>If you know a solution for this problem please tell me. I really need to solve this problem because it is very important for my project to be able to draw and redraw :/</p> <p>Thank you!</p>

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.
