Palette does not support getNodeDefaults

[endeffects]

I'm trying to create new nodes from palette, but all i get is a clone of the existing node in the palette. So i was looking into your docu and for other frameworks this is done by using getNodeDefaults and getConnectorDefaults. But this seems not to be fully supported in the current version.

Also i got an issue that when i try to add such a clone to my diagram that it does not deselect itself after dropping it. I'm not able to do anything in this state. The console shows the following error:

treemap.ts:2 Error: attribute width: A negative value is not valid. ("-1.7976931348623157e+308")

Btw: The node is an inherited DiagramNode Instance.

So i was looking into your docu and for other frameworks this is done by using getNodeDefaults and getConnectorDefaults. But this seems not to be fully supported in the current version.	Currently we don’t have getNodeDefaults and getConnectorDefaults support in Blazor. We have logged this as a feature request and it will be available in our Volume 3 release on October 2019. We will get back to you once our Volume 3 release is rolled out.   We have created simple sample to achieve drag and drop elements from palette to Diagram. Please refer to the sample as below.     Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/SymbolPaletteSample-2027363582

("-1.7976931348623157e+308")	We were unable to replicate an issue  with the dropped objects. Could you check the provided sample ? Please provide us the video or modified sample if this issue still exists.

Thanks for your help, i have uploaded a sample here:
https://1drv.ms/u/s!AvfU-VGBgXuLg-o1FobpHy9VVnqADg?e=QxFQEv

Please drag and drop multiple elements from palette to force the issue.
If the error does not occure you maybe have to restart the application.
Sometimes it works well, sometimes not.

Hi @endeffects ,

Thanks for sharing the sample to represent the issue.

The reported issue occurs due to a node and connector id starts with number. For an SVG element, an id should start with a letter, non-ASCII letters. Please refer to below link.

We have modified the sample based on the above guideline to resolve the issue. Please refer to the modified sample as below.

Sample Link: https://www.syncfusion.com/downloads/support/directtrac/240032/ze/Syncfusion-DragDrop-527797951

Sample changes: We have changed id of the node and connector in BasedNode.razor.cs and Connector.cs files.
