• Switching getSymbol() to retrieve the symbol via PmadMilsymbolSelector bypasses the previous concatenation logic. Ensure that the selector instance is always initialized before this method is called to avoid unexpected results.

return PmadMilsymbolSelector.getInstance('sidc').getValue();

• Ensure that the new pmad-symbol-selector component fully replicates the functionality and interactions of the previous bootstrap-select setup, including proper initialization and event handling.

<pmad-symbol-selector id="sidc" name="" layout="Extended" />
